Simultaneous antegrade and retrograde endoscopic surgery for benign prostatic hyperplasia with vesical calculi – A single-centre experience Publication date: Available online 11 June 2018 Source:Arab Journal of Urology Author(s): Tarun Javali, Arvind Nayak K, S.M.L. Prakash Babu ObjectiveTo describe the effectiveness and safety of our novel technique of simultaneous percutaneous cystolithotripsy with transurethral resection of prostate (TURP) for patients with benign prostatic hyperplasia (BPH) complicated with large vesical calculi.Patients and methodsThis was a retrospective analysis of 25 patients who underwent simultaneous percutaneous cystolithotripsy with TURP between January 2012 and January 2016. Technique: A 28-F Amplatz sheath was inserted percutaneously into the bladder after sequential dilatation under cystoscopic guidance. Percutaneous cystolithotripsy using a nephroscope and pneumatic lithoclast was then performed simultaneously along with monopolar TURP. Preoperative parameters reviewed included: patient’s symptoms, International Prostate Symptom Score, uroflowmetry pattern, prostate volume, and stone burden on ultrasonography of the abdomen and pelvis. Postoperative parameters analysed included: duration of irrigation, time until catheter removal, length of hospital stay, and complications.ResultsThe mean age of the patients was 67.8 years. The mean prostate size was 62.28 mL and the mean stone burden was 3.18 cm. The mean operating time was 54.2 min. The mean time until catheter removal was 3.2 days.ConclusionSimultaneous percutaneous cystolithotripsy with TURP in patients with BPH with large bladder calculi is safe and feasible.
Selective embolisation for intractable bladder haemorrhages: A systematic review of the literature Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Diaa-Eldin Taha, Ahmed A. Shokeir, Omar A. Aboumarzouk ObjectiveTo establish the current evidence and assess the effectiveness and safety of selective transarterial embolisation (STE) to control intractable bladder haemorrhage (IBH).Materials and methodsWith a rise in the use of STE for the treatment of IBH, a systematic review was performed according to the Cochrane reviews guidelines and in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist.ResultsThe literature search yielded 38 studies, of which 11 were excluded because of irrelevance of data. All included studies were observational cohort studies, with no randomisation or control groups apart from in relation to the materials used for embolisation. The studies were published between 1978 and 2016. There were 295 patients with an age range between 51 and 95 years. The success rate ranged from 43% up to 100%. The most reported complication was post-embolisation syndrome, although other complications were described such as mild transient gluteal claudication, nausea, and vomiting.ConclusionSTE of the internal iliac artery is a safe and effective alternative technique to control severe IBH, and has been successfully applied over many years to treat bladder haemorrhage associated with terminal pelvic malignancy.
Preliminary study of prevalence for bladder cancer in Isfahan Province, Iran Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Hamid Mazdak, Zahra Tolou-Ghamari ObjectivesTo clarify period prevalence (PP), incidence rate (Ir), and reported mortality for patients with bladder cancer (BC) in Isfahan Province/Iran, as BC is the most common cancer of the urinary tract in Iran and other parts of the world.Patients and methodsData from 21 March 2011 to 3 March 2015 was obtained from the Isfahan Cancer Registry. BC was distinguished by the related established topography code (C67). Ir and PP were calculated and expressed per 100 000 persons.ResultsIn all, 279 females and 1376 males were identified. For the total population the PP was calculated as 33.2. This value corresponded to a PP of 54.4 for males and 11.4 for females (P < 0.001). Histologically, 63% of patients had invasive BC. Irs versus mortality rates were calculated for each year, i.e. 2011–2012, 2012–2013, 2013–2014, and 2014–2015, as 7.7 vs 0.56, 8.1 vs 0.74, 7.4 vs 0.98, and 9.9 vs 0.84, respectively. The mean (SD, range) age of the patients was 65.2 (13.9, 3–100) years. In relation to the age of the study population, BC occurred in 12% of patients aged <50 years and in 15% of those aged ≥80 years.ConclusionThe PP for BC in the male population was 4.8-times higher than females. There was a 28.6% increase in the Ir over the study period. Further study concerning environmental exposure, genetic factors, job-related exposure to various chemical carcinogens, and geographical distribution in Isfahan and its’ rural provinces would seem to be valuable.
Repair of panurethral stricture: Proximal ventral and distal dorsal onlay technique of buccal mucosal graft urethroplasty Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Subbarao Chodisetti, Yogesh Boddepalli, Malakondareddy Kota ObjectiveTo report the surgical details and results of our technique of buccal mucosal graft (BMG) urethroplasty for panurethral stricture, as many studies have reported repair of panurethral stricture by single-stage BMG urethroplasty by placing buccal mucosa ventrally, dorsally or dorsolaterally.Patients and methodsThis was an observational analysis of 38 patients with panurethral stricture treated by placing two BMGs, one as a ventral onlay in the proximal bulbar urethra and the other as a dorsal onlay in the distal bulbar and penile urethra. Success was defined as asymptomatic state with or without need for a postoperative single intervention such as dilatation or internal urethrotomy.ResultsThe 38 patients had a mean age of 44 years, with lichen sclerosus as the predominant cause of stricture. The ultimate success rate was 84.2% at the end of 3 months and 89.5% at the end of 1 year. Recurrent strictures appeared only in the failed cases during the follow-up period of 11 months. None of the patients needed redo urethroplasty during the follow-up period.ConclusionsA proximal ventral and distal dorsal onlay technique of BMG urethroplasty is an available alternative for repairing panurethral stricture. The technique described is simple and easily reproducible with encouraging results compared to other similar techniques.
Neo-glans reconstruction for penile cancer: Description of the primary technique using autologous testicular tunica vaginalis graft Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Peter Weibl, Christina Plank, Rudolf Hoelzel, Stefan Hacker, Mesut Remzi, Wilhelm Huebner Partial penectomy (glansectomy with/or without distal corporectomy) is an acceptable alternative for smaller distal pT3 penile carcinoma lesions in highly motivated and compliant patients. The authors describe a novel technique of neo-glans reconstruction using a tunica vaginalis (TV) testis allograft. However, due to an unclear resection margin on final histology, the patient underwent re-do surgery with a neo-glans revision using the well-established mesh split-thickness skin graft (STSG) technique. The penile length was preserved and the penile and bulbar part of the urethra was additionally mobilised in order to obtain a natural and aesthetic result for the meatus.Neo-glans reconstruction with TV coverage may be another promising alternative, which certainly requires further evaluation. We believe that the donor-site associated morbidity is minimal when compared to other harvesting sites. However, this is just an assumption, because direct comparison data on grafting techniques and neo-glans reconstruction are not available. Nevertheless, we think that for re-do procedures a standardised approach using a STSG technique should be the treatment method of choice.
Twin penile skin flap, is it the answer for repair of long anterior urethral strictures? Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Diaaeldin Mostafa, Hisham Elshawaf, M. Kotb, Abdelwahab Elkassaby ObjectiveTo present our twin ventral penile skin flap technique for the management of complex long anterior urethral strictures not caused by lichen sclerosis (LS), with evaluation of surgical outcome and complications.Patients and methodsWe retrospectively reviewed patients diagnosed with long complex anterior urethral strictures who were all referred to Ain Shams University hospital and operated on by three reconstructive surgeons. The surgical procedure was carried out as follows: exposure of the urethra through a ventral longitudinal penile skin incision and another perineal incision; two ventral longitudinal dartos-based penile skin flaps are used for urethral augmentation as onlay flaps. Clinical data were collected in a dedicated database. Preoperative, intraoperative, and postoperative follow-up data for each patient were recorded and analysed. A descriptive data analysis was performed.ResultsBetween January 2012 and February 2015, 47 patients diagnosed by urethrograms as having long anterior urethral strictures, with a mean (SD, range) length of 17.56 (2.09; 14–21) cm, were managed by twin penile skin flap repair. Four patients were lost to follow-up, thus 43 patients constituted the study cohort. The mean (range) follow-up period was 31 (22–36) months. The overall success rate was 95.35% (41/43). At 12-months postoperatively, the 41 successful cases had a mean (SD, range) peak urinary flow rate of 20.26 (3.06, 14–25) mL/s and American Urological Association Symptom Score of 5.6 (1.85, 3–8). Postoperative complications included urethrocutaneous fistula in three patients (6.97%), mild sacculation of the flap in seven patients (16.52%), post-micturition dribbling in 34 patients (79.07%), decreased penile girth in two patients (4.65%), and chordae of <15° with no need for repair in three patients (6.97%).ConclusionsIn the presence of a favourable urethral plate and ample non-hirsute penile skin, one-stage twin penile skin flap urethroplasty provides excellent results for non-LS related complex strictures, with minimal acceptable complications. It proved to be especially efficient in circumcised patients.
Clitoroplasty: A variant of the technique by Acimi Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Smail Acimi, Mohammed Ali Acimi, Lamia Debbous, Mimouna Bessahraoui, Ibtisseme Bouanani ObjectivesTo evaluate the mid-term results of clitoroplasty through the reduction of the length and diameter of the corpus cavernosum, as well as the volume of the glans.Patients and methodsFrom October 2003 to July 2015, we performed 29 clitoroplasties using the described procedure. The median (range) age of the patients was 18 (3–47) months. After surgery we evaluated the volume of the clitoris, the appearance of glans, and its sensitivity to light touch, pressure, and pain.ResultsThe length of the apparent part of the glans remained large (>10 mm) in four patients (14%), was an average size (between 5 and 10 mm) in 11 (39%), and small (<5 mm) in 13 (46%). The length of the corpus cavernosum was <20 mm and its diameter <5 mm in all cases. The sensitivity of the reduced clitoris to touch, pressure and pain seemed normal in all patients. In addition, we never found the circumflex arteries and nerves of the penis (on histological examination of excised pieces of corpus cavernosum) in all children operated on during the first 3 years of life. The circumflex arteries of the penis begin to develop, only after the fourth year. This anatomical finding is an argument for performing clitoroplasty at an early age to avoid any risk of intraoperative and postoperative bleeding.ConclusionsThe sensitivity of the clitoral glans appeared to be normal in all cases, with a good cosmetic appearance of the external genitalia in most patients.
Influence of postnatal hydroureter in determining the need for voiding cystourethrogram in children with high-grade hydronephrosis Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Amr Hodhod, John-Paul Capolicchio, Roman Jednak, Eid El-Sherif, Abd El-Alim El-Doray, Mohamed El-Sherbiny ObjectiveTo evaluate the utility of hydroureter (HU) to identify high-grade vesico-ureteric reflux (VUR) in patients with high-grade postnatal hydronephrosis (PH).Patients and methodsWe retrospectively reviewed patients’ charts that had antenatal hydronephrosis from 2008 to 2014. Patients were excluded if they presented with febrile urinary tract infection (fUTI), neurogenic bladder, posterior urethral valve, multi-cystic dysplastic kidney, and multiple congenital malformations. We reviewed postnatal ultrasonography images and patients with Society of Fetal Urology (SFU) Grades 3 and 4 hydronephrosis with a renal pelvic antero-posterior diameter of ≥10 mm were included. The ureter was assessed and considered dilated if the ureteric diameter was ≥4 mm. The voiding cystourethrogram (VCUG) studies, fUTI incidence, and surgical reports were reviewed.ResultsOf the 654 patients reviewed, we included 148 patients (164 renal units) of whom 113 (76.4%) were male and 35 (23.6%) female. SFU Grade 3 PH was identified in 49% of the renal units, with the remaining 51% being SFU Grade 4. HU was found in 50/164 renal units and was not detected in the remaining 114 units. VUR was diagnosed in four units (3.5%) without HU (low-grade VUR); whilst it was detected in 19 units (38%) with HU (72.7% were high-grade VUR) (P < 0.001). VUR was diagnosed on the contralateral side in four/105 patients with PH without HU and diagnosed in 10/43 patients with PH with HU (P < 0.001). During a median follow-up of 25.9 months, none of the renal units that had VUR without HU developed UTI or had surgeries.ConclusionLow-grade uncomplicated VUR was diagnosed in 3.5% of renal units without HU. Our results support limiting the use of VCUG to renal units with PH if associated with HU.
Comparing tamsulosin, silodosin versus silodosin plus tadalafil as medical expulsive therapy for lower ureteric stones: A randomised trial Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Md Jawaid Rahman, M. Shazib Faridi, Naloh Mibang, Rajendra Sinam Singh ObjectiveTo compare the efficacy of tamsulosin, silodosin, and silodosin plus tadalafil as medical expulsive therapy (MET) for distal ureteric calculi.MethodsIn all, 120 patients who met the inclusion criteria were randomised into one of three treatment arms: tamsulosin (Group A), silodosin (Group B), and silodosin plus tadalafil (Group C). The drugs were given for a maximum of 4 weeks. The primary endpoint was the stone expulsion rate and secondary endpoints were stone expulsion time, number of pain episodes, and side-effects associated with MET. The follow-up period was for 4 weeks, after which ureteroscopic lithotripsy was done to remove any stones that were not expelled.ResultsThere was a statistically significantly higher stone expulsion rate in Group C (90%) as compared to groups A (57.5%) and B (77.5%) with a shorter mean time to stone expulsion. Also, there were statistically fewer pain episodes in Group C as compared to groups A and B. There were no serious side-effects.ConclusionThe present study concludes that the combination of silodosin and tadalafil increases the ureteric stone expulsion rate and decreases the expulsion time significantly. This combination provided significantly better control of pain without any serious side-effects.
War-related penile injuries in Libya: Single-institution experience Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Abdalla M. Etabbal, Fathi F. Hussain, Mohamed O. Benkhadoura, Abdalla M. Banni ObjectiveTo report on our initial experience in the management of war-related penile injuries; proper diagnosis and immediate treatment of penile injuries is essential to gain satisfactory results. Besides treating primary wounds and restoring penile function, the cosmetic result is also an important issue for the surgeon.Patients and methodsThe study was conducted in the Department of Urology at Benghazi Medical Center and comprised all patients who presented with a shotgun, gunshot or explosive penile injury between February 2011 and August 2017. The patient’s age, cause of injury, site and severity of injuries, management, postoperative complications, and hospital stay, were recorded.ResultsIn all, 29 males with war-related penile injuries were enrolled in the study. The mean (SD) age of these patients was 31.3 (10.5) years. The glans, urethra, and corporal bodies were involved in four (13.7%), 10 (34.4%), and 20 (68.9%) of the patients, respectively. According to the American Association for the Surgery of Trauma Penis Injury Scale, Grade III penile injuries were the most common (11 patients, 37.9%). The most common post-intervention complications were urethral stricture with or without proximal urethrocutaneous fistula (eight patients, 27.5%), followed by permanent erectile dysfunction (five patients, 17.2%).ConclusionIn patients who sustain war-related penile injuries the surgeon’s efforts should not only be directed to restoring normal voiding and erectile function but also on the cosmetic appearance of the penis.
Uretero-arterial fistula due to a hypogastric aneurysm Publication date: June 2018 Source:Arab Journal of Urology, Volume 16, Issue 2 Author(s): Augustin Pirvu Uretero-arterial fistula is a rare condition that can result in life-threatening haematuria, which should be diagnosed and treated immediately. We report a case of uretero-arterial fistula due to a hypogastric aneurysm. The patient underwent an endovascular treatment of the hypogastric aneurysm associated with a percutaneous nephrostomy. Most fistulae are not identified on computed tomography (CT) and a high degree of suspicion is needed. Presence of unexplained haematuria with CT diagnosis of hypogastric aneurysm should raise suspicions of uretero-arterial fistula as a possible cause.
Successful management of ureteric endometriosis by laparoscopic ureterolysis – A review and report of three further cases Publication date: Available online 31 May 2018 Source:Arab Journal of Urology Author(s): Deepa Talreja, Vivek Salunke, Shinjini Pande, Chirag Gupta ObjectiveTo review articles highlighting the effectiveness of conservative laparoscopic ureterolysis as a primary treatment option in patients with ureteric endometriosis and to report on a further three cases.Patients and methodsPubMed, EMBASE, Cochrane database were searched to identify articles reporting cases of laparoscopic management of ureteric endometriosis and, in particular management by ureterolysis. We further described three new cases of ureteric endometriosis managed at our institute.ResultsThe present study illustrates the significance of laparoscopic ureterolysis in the management of patients with ureteric endometriosis. In our cases, a systematic surgical approach was followed in order to perform complete but careful excision of the all visible endometriotic implants. During follow-up successful treatment was established by relief of hydroureteronephrosis by ultrasonographic evaluation.ConclusionConsidering the risk of loss of renal function and due to the nonspecific symptoms, a prompt clinical suspicion and thorough preoperative assessment can potentially help in the diagnosis. We conclude that laparoscopic ureterolysis is a minimally invasive technique with low complication and recurrence rates. It is a suitable option as a primary approach for selected patients with ureteric endometriosis, if done in a systematic step-by-step approach.
Different approaches to the prostate: The upcoming role of a purpose-built single-port robotic system Publication date: Available online 24 May 2018 Source:Arab Journal of Urology Author(s): Jihad Kaouk, Juan Garisto, Riccardo Bertolo With the aim of minimising the patient’s postoperative pain, expediting recovery and improving cosmesis, the idea of performing a laparoscopic procedure through a single abdominal incision was introduced. In the present report, we describe five different access routes to the prostate that may be at the surgeon’s disposal with the potential of decreasing patient’s perioperative morbidity. Robotic radical prostatectomy has been refined and became a standard of care in surgery for localised prostate cancer. The advent of single-port robotic surgery has prompted the re-discovery of different access routes to the prostate and ideally all of them are feasible. The potential for avoiding the abdominal cavity will decrease the surgical morbidity and minimise the surgical dissection. In the near future, each of the described approaches could be chosen on the basis of the patient’s preoperative comorbidities, body habitus, anatomy, and disease characteristics and location.
Bilateral same-session flexible ureterorenoscopy for renal and/or ureteric stone disease treatment Publication date: Available online 18 May 2018 Source:Arab Journal of Urology Author(s): Ersan Arda, Basri Cakiroglu ObjectiveTo evaluate the effectiveness and safety of bilateral same-session flexible ureterorenoscopy (f-URS) in the treatment of bilateral renal and/or ureteric stone disease.Patients and methodsFrom October 2007 to December 2015, 62 patients who had undergone bilateral, same-session f-URS were included in the study. The procedures were performed under general anaesthesia, in lithotomy, and initiated on the side in which the patient was clinically symptomatic or on the side in which the stone was smaller. Plain abdominal radiography, intravenous urography, renal ultrasonography and/or non-contrast computed tomography scans were conducted in all patients. The success rate was defined as, patients who were stone-free or only had residual fragments of <3 mm.ResultsA total of 62 patients (43 male, 19 female), with a mean (SD) age of 39 (15.1) years, were included. The mean (SD) stone size was 23.2 (6.11) mm with a mean (SD) operative time of 58.8 (16.24) min. The stone-free rates were 90.3% and 100% after the first and second procedures, respectively. The mean (SD) hospital stay was 1.58 (0.72) days. There were minor complications (Clavien–Dindo grade I–II) in 10 (16%) patients and major complications (Clavien–Dindo III–IV), e.g. distal ureter laceration and laser injury of the ureter, in two patients.ConclusionSame session bilateral f-URS is a successful and safe method for bilateral renal and/or ureteric stones.
Robot-assisted radical cystectomy with intracorporeal urinary diversion – The new ‘gold standard’? Evidence from a systematic review Publication date: Available online 11 April 2018 Source:Arab Journal of Urology Author(s): Niyati Lobo, Ramesh Thurairaja, Rajesh Nair, Prokar Dasgupta, Muhammad Shamim Khan ObjectiveTo investigate whether a totally intracorporeally radical cystectomy (RC) can be considered the new ‘gold standard’ in bladder cancer, as open RC (ORC) is the current ‘gold standard’ for surgical treatment of muscle-invasive and high-grade non-muscle-invasive bladder cancer. However, robot-assisted radical cystectomy (RARC) is becoming the preferred surgical approach in many centres as it seems to maintain the oncological control of open surgery whilst offering improved perioperative benefits.Materials and methodsA review of the literature was conducted using the Pubmed/MEDLINE, ISI Web of Knowledge and Cochrane Databases to identify studies that included both ORC and RARC with intracorporeal and extracorporeal urinary diversion (UD) published up to July 2017.ResultsEvidence from four single-centre randomised controlled trials and now the multicentre Randomized Trial of Open versus Robotic Cystectomy (RAZOR) trial demonstrate the oncological equivalence of RARC to ORC. The only convincing evidence for the superiority of RARC is in the area of blood loss and transfusion rates. However, the UD procedure in these trials was performed extracorporeally and, to realise the full benefits of RARC, a totally intracorporeal approach is needed. Intracorporeal UDs (ICUDs) have been shown to be technically feasible by a few expert centres and have demonstrated some improved short-term perioperative outcomes compared to extracorporeal UDs.ConclusionsAlthough initial outcomes appear promising, RARC with ICUD is far from gaining ‘gold standard’ status. Further studies are needed to confirm that outcomes are reproducible widely. Furthermore, the benefits of a totally intracorporeal approach must be confirmed in randomised controlled trials.
Laparoscopic renal surgery is here to stay Publication date: Available online 6 March 2018 Source:Arab Journal of Urology Author(s): Angus Chin On Luk, Rajadoss Muthu Krishna Pandian, Rakesh Heer ObjectivesTo review the current literature comparing the outcomes of renal surgery via open, laparoscopic and robotic approaches.Materials and methodsA comprehensive literature search was performed on PubMed, MEDLINE and Ovid, to look for studies comparing outcomes of renal surgery via open, laparoscopic, and robotic approaches.ResultsLimited good-quality evidence suggests that all three approaches result in largely comparable functional and oncological outcomes. Both laparoscopic and robotic approaches result in less blood loss, analgesia requirement, with a shorter hospital stay and recovery time, with similar complication rates when compared with the open approach. Robotic renal surgeries have not shown any significant clinical benefit over a laparoscopic approach, whilst the associated cost is significantly higher.ConclusionWith the high cost and lack of overt clinical benefit of the robotic approach, laparoscopic renal surgery will likely continue to remain relevant in treating various urological pathologies.

Geographical differences in semen characteristics of 13 892 infertile men Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Haitham Elbardisi, Ahmad Majzoub, Sami Al Said, Khalid Al Rumaihi, Walid El Ansari, Alia Alattar, Mohamed Arafa ObjectiveTo assess the relationship between geographical differences and all semen parameters, across 13,892 infertile men of 84 diverse nationalities, recruited at a specialised tertiary hospital that represents the main healthcare provider in Qatar. Male infertility is an important and global public health problem. Despite this, there is a significant scarcity of epidemiological male infertility and semen analysis research in the Middle East and North Africa (MENA) region, as well as geographical comparisons with other parts of the world.Patients and methodsRetrospective study of semen findings of 13 892 infertile men assessed at the Male Infertility Unit at Hamad Medical Corporation, in Qatar between January 2012 and August 2015. Based on country of origin, patients were categorised into those from the MENA region (n = 8799) and non-MENA patients (n = 5093). The two groups were compared across demographic features and semen characteristics: age, sperm volume, sperm total motility, sperm progressive motility (PMot), abnormal sperm forms (ABF), and sperm DNA fragmentation (SDF).ResultsThe whole sample’s mean (SD) age was 35.7 (0.7) years, sperm concentration was 32.3 (0.25) × 106 sperm/mL, total motility was 45.4 (0.2)%, sperm PMot was 25.1 (0.2)%, and ABF was 79.9 (0.2)%. Overall, 841 patients had azoospermia (6.05%), 3231 had oligospermia (23.3%), 4239 had asthenospermia (30.5%) and 6772 had teratospermia (48.7%). SDF (1050 patients) was abnormal in 333 patients (31.7%). MENA patients were significantly younger than their non-MENA counterparts and had a greater semen volume. Non-MENA patients had significantly higher sperm counts, total motility and PMot, and lower ABF. SDF showed no statistical difference between the two groups. MENA patients had significantly higher prevalence of oligospermia, asthenospermia, and teratospermia; and lower prevalence of normal sperm concentration, normal motility, and normal morphology. Throughout the 4 years of the study, MENA patients constantly had significantly lower sperm counts; generally lower sperm total motility percentage and generally lower quality sperm morphology. We compared patients by age (≤40 and >40 years): in the patients aged ≤40 years, the same results as for the overall study were reproduced; in the >40-years group, the same results were reproduced with the exception of morphology, which was not significantly different between the MENA and non-MENA patients.ConclusionSemen quality is generally lower in male infertility patients from the MENA region compared to non-MENA regions.
Lifestyle causes of male infertility Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Damayanthi Durairajanayagam ObjectiveTo examine the potential effects of lifestyle factors on male reproductive health. Evidence of a global decline in human sperm quality over recent decades has been accumulating. Environmental, occupational, and modifiable lifestyle factors may contribute to this decline. This review focuses on key lifestyle factors that are associated with male infertility such as smoking cigarettes, alcohol intake, use of illicit drugs, obesity, psychological stress, advanced paternal age, dietary practices, and coffee consumption. Other factors such as testicular heat stress, intense cycling training, lack of sleep and exposure to electromagnetic radiation from mobile phone use are briefly discussed.Materials and methodA comprehensive literature search was performed to identify and synthesise all relevant information, mainly from within the last decade, on the major lifestyle factors associated with male infertility and semen quality. Database searches were limited to reports published in English only. A manual search of bibliographies of the reports retrieved was conducted to identify additional relevant articles.ResultsIn all, 1012 articles were identified from the database search and after reviewing the titles and abstract of the reports, 104 articles met the inclusion criteria. Of these, 30 reports were excluded as the full-text could not be retrieved and the abstract did not have relevant data. The remaining 74 reports were reviewed for data on association between a particular lifestyle factor and male infertility and were included in the present review.ConclusionThe major lifestyle factors discussed in the present review are amongst the multiple potential risk factors that could impair male fertility. However, their negative impact may well be mostly overcome by behaviour modification and better lifestyle choices. Greater awareness and recognition of the possible impact of these lifestyle factors are important amongst couples seeking conception.
Role of sperm DNA fragmentation in male factor infertility: A systematic review Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Chak-Lam Cho, Ashok Agarwal ObjectiveTo summarise the latest evidence on the role of sperm DNA fragmentation (SDF) in male factor infertility, as SDF has been emerging as a valuable tool for male infertility evaluation.MethodsA search of PubMed was conducted using the keywords ‘sperm DNA fragmentation’ and ‘male infertility’. Studies in languages other than English were excluded. All identified studies were screened and clinical studies in humans were included.ResultsIn all, 150 articles were included for analysis. Current evidence supports the association between high SDF and poor reproductive outcomes for natural conception and intrauterine insemination. Although the relationship between high SDF and in vitro fertilisation and intracytoplasmic sperm injection is less clear, the negative implication of high SDF on pregnancy loss is evident. Various treatment strategies have been attempted with varying success. The predictive value of SDF testing on outcomes of natural pregnancy and assisted reproduction illustrates its value in clinical practice.ConclusionThe significant role of SDF in male factor infertility is supported by current evidence. The beneficial role of SDF testing in selection of varicocelectomy candidates, evaluation of patients with unexplained infertility and recurrent pregnancy loss, selection of the most appropriate assisted reproductive technique with highest success rate for infertile couples, and assessment of infertile men with modifiable lifestyle factors or gonadotoxin exposure has been recently proposed.
Role of reactive oxygen species in male infertility: An updated review of literature Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Hillary Wagner, Julie W. Cheng, Edmund Y. Ko ObjectivesTo review the literature and provide an updated summary on the role of reactive oxygen species (ROS) in male infertility.MethodsA review of PubMed, Cochrane review, and Web of Science databases for full-text English-language articles published between 1943 and 2017 was performed, focusing on the aetiology of ROS, physiological role of ROS on spermatic function, pathological role of ROS in infertility, evaluation of ROS, and role of antioxidants in oxidative stress.ResultsROS play a role in spermatic function and fertilisation. The literature describes both a physiological and a pathological role of ROS in fertility. A delicate balance between ROS necessary for physiological activity and antioxidants to protect from cellular oxidative injury is essential for fertility.ConclusionAlthough elevated levels of ROS are implicated as a cause of infertility, there is no consensus on selecting patients to test for ROS, which test to perform, or if treatment for ROS can have a positive impact on infertility rates and pregnancy.
Hyperprolactinaemia in male infertility: Clinical case scenarios Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Zeinab Dabbous, Stephen L Atkin ObjectiveTo explore the evaluation, treatment and impact of hyperprolactinaemia on male infertility and testicular function, as hyperprolactinaemia is commonly detected during the evaluation of infertile men.MethodsA literature search was performed using MEDLINE/PubMed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify all studies exploring hyperprolactinaemia in male infertility.ResultsElevated levels of serum prolactin have a detrimental effect on male reproduction through inhibition of the pulsatile release of gonadotrophins from the anterior pituitary gland, and a direct effect on spermatogenesis. Treatment of confirmed hyperprolactinaemia with dopamine agonists leads to significant improvements in both semen parameters and hormone levels.ConclusionHyperprolactinaemia, both directly and indirectly, has a negative effect on sperm production, and its detection and management in men seeking fertility is mandatory.
A systematic review on the genetics of male infertility in the era of next-generation sequencing Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Amal Robay, Saleha Abbasi, Ammira Akil, Haitham El-Bardisi, Mohamed Arafa, Ronald G. Crystal, Khalid A. Fakhro ObjectivesTo identify the role of next-generation sequencing (NGS) in male infertility, as advances in NGS technologies have contributed to the identification of novel genes responsible for a wide variety of human conditions and recently has been applied to male infertility, allowing new genetic factors to be discovered.Materials and methodsPubMed was searched for combinations of the following terms: ‘exome’, ‘genome’, ‘panel’, ‘sequencing’, ‘whole-exome sequencing’, ‘whole-genome sequencing’, ‘next-generation sequencing’, ‘azoospermia’, ‘oligospermia’, ‘asthenospermia’, ‘teratospermia’, ‘spermatogenesis’, and ‘male infertility’, to identify studies in which NGS technologies were used to discover variants causing male infertility.ResultsAltogether, 23 studies were found in which the primary mode of variant discovery was an NGS-based technology. These studies were mostly focused on patients with quantitative sperm abnormalities (non-obstructive azoospermia and oligospermia), followed by morphological and motility defects. Combined, these studies uncover variants in 28 genes causing male infertility discovered by NGS methods.ConclusionsMale infertility is a condition that is genetically heterogeneous, and therefore remarkably amenable to study by NGS. Although some headway has been made, given the high incidence of this condition despite its detrimental effect on reproductive fitness, there is significant potential for further discoveries.
A systematic review on sperm DNA fragmentation in male factor infertility: Laboratory assessment Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Manesh Kumar Panner Selvam, Ashok Agarwal ObjectiveTo review sperm DNA fragmentation (SDF) testing as an important sperm function test in addition to conventional semen analysis. High SDF is negatively associated with semen quality, the fertilisation process, embryo quality, and pregnancy outcome. Over recent decades, different SDF assays have been developed and reviewed extensively to assess their applicability and accuracy as advanced sperm function tests. Amongst them, the standardisation of the terminal deoxynucleotidyl transferased UTP nick-end labelling (TUNEL) assay with a bench top flow cytometer in clinical practice deserves special mention with a threshold value of 16.8% to differentiate infertile men with DNA damage from fertile men.Materials and methodsA systematic literature search was performed through the PubMed, Medline, and ScienceDirect databases using the keywords ‘sperm DNA fragmentation’ and ‘laboratory assessment’. Non-English articles were excluded and studies related to humans were only included.ResultsOf the 618 identified, 87 studies (original research and reviews) and in addition eight book chapters meeting the selection criteria were included in this review. In all, 366 articles were rejected in the preliminary screening and a further 165 articles related to non-human subjects were excluded.ConclusionThere are pros and cons to all the available SDF assays. TUNEL is a reliable technique with greater accuracy and as an additional diagnostic test in Andrology laboratories along with basic semen analysis can predict fertility outcome, and thus direct the choice of an assisted reproductive technology procedure for infertile couples. Also, the TUNEL assay can be used as a prognostic test and results are beneficial in deciding personalised treatment for infertile men.
Laboratory assessment of oxidative stress in semen Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Ashok Agarwal, Emily Qiu, Rakesh Sharma ObjectivesTo evaluate different laboratory assessments of oxidative stress (OS) in semen and identify a cost-efficient and highly sensitive instrument capable of providing a comprehensive measure of OS in a clinical setting, as early intervention and an accurate diagnostic test are important because they help maintain a balance of free radicals and antioxidants; otherwise, excessive OS could lead to sperm damage and result in male infertility.Materials and methodsA systematic literature search was performed through a MedLine database search using the keywords ‘semen’ AND ‘oxygen reduction potential’. We also reviewed the references of retrieved articles to search for other potentially relevant research articles and additional book chapters discussing laboratory assessments for OS, ranging from 1994 to 2017. A total of 29 articles and book chapters involving OS-related laboratory assays were included. We excluded animal studies and articles written in languages other than English.ResultsDirect laboratory techniques include: chemiluminescence, nitro blue tetrazolium, cytochrome C reduction test, fluorescein probe, electron spin resonance and oxidation–reduction potential (ORP). Indirect laboratory techniques include: measurement of Endtz test, lipid peroxidation, chemokines, antioxidants/micronutrients/vitamins, ascorbate, total antioxidant capacity, or DNA damage. Each of these laboratory techniques has its advantages and disadvantages.ConclusionTraditional OS laboratory assessments have their limitations. Amongst the prevalent laboratory techniques, ORP is novel and better option as it can be easily used in a clinical setting to provide a comprehensive review of OS. However, more studies are needed to evaluate its reproducibility across various laboratory centres.
Oxidation–reduction potential and sperm DNA fragmentation, and their associations with sperm morphological anomalies amongst fertile and infertile men Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Ahmad Majzoub, Mohamad Arafa, Mohamed Mahdi, Ashok Agarwal, Sami Al Said, Ibrahim Al-Emadi, Walid El Ansari, Alia Alattar, Khalid Al Rumaihi, Haitham Elbardisi ObjectiveTo assess seminal oxidation–reduction potential (ORP) and sperm DNA fragmentation (SDF) in male infertility and their relationships with sperm morphology in fertile and infertile men.Patients and methodsProspective case-control study comparing the findings of infertile men (n = 1168) to those of men with confirmed fertility (n = 100) regarding demographics and semen characteristics (conventional and advanced semen tests). Spearman rank correlation assessed the correlation between ORP, SDF, and different morphological indices. Means of ORP and SDF were assessed in variable levels of normal sperm morphology amongst all participants.ResultsInfertile patients had a significantly lower mean sperm count (32.7 vs 58.7 × 106 sperm/mL), total motility (50.1% vs 60.4%), and normal morphology (5.7% vs 9.9%). Conversely, infertile patients had significantly higher mean head defects (54% vs 48%), and higher ORP and SDF values than fertile controls. ORP and SDF showed significant positive correlations and significant negative correlations with sperm head defects and normal morphology in infertile patients, respectively. ORP and SDF were significantly inversely associated with the level of normal sperm morphology. Using receiver operating characteristic curve analysis, ORP and SDF threshold values of 1.73 mV/106 sperm/mL and 25.5%, respectively, were associated with 76% and 56% sensitivity and 72% and 72.2% specificity, respectively, in differentiating <4% from ≥4% normal morphology.ConclusionA direct inverse relationship exists between seminal ORP and SDF with various levels of normal sperm morphology. Using ORP and SDF measures in conjunction with standard semen morphology analysis could validate the result of the fertility status of patients.
Prediction of male infertility by the World Health Organization laboratory manual for assessment of semen analysis: A systematic review Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Amir S. Patel, Joon Yau Leong, Ranjith Ramasamy ObjectiveTo discuss the role, reliability and limitations of the semen analysis in the evaluation of fertility with reference to the World Health Organization (WHO) fifth edition guidelines, with semen analysis reference values published in 2010. We also discuss the limitations of using a single threshold value to distinguish ‘abnormal’ and ‘normal’ parameters.MethodsThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to search the MEDLINE, EMBASE, and the Cochrane electronic database for articles discussing the effectiveness of semen analysis.ResultsLimitations affecting the reliability of semen analysis as a predictor of fertility were found. These include: the lack of consideration of the female factor, the vaguely defined threshold values, and the intra-individual variation in semen parameters.ConclusionsImpaired semen parameters alone cannot be used to predict fertility as these men still have a chance of being fertile, except when a man has azoospermia, necrospermia or globozoospermia.
Update on the proteomics of male infertility: A systematic review Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Manesh Kumar Panner Selvam, Ashok Agarwal ObjectiveTo assess the role of differentially expressed proteins as a resource for potential biomarker identification of infertility, as male infertility is of rising concern in reproductive medicine and evidence pertaining to its aetiology at a molecular level particularly proteomic as spermatozoa lack transcription and translation. Proteomics is considered as a major field in molecular biology to validate the target proteins in a pathophysiological state. Differential expression analysis of sperm proteins in infertile men and bioinformatics analysis offer information about their involvement in biological pathways.Materials and methodsLiterature search was performed on PubMed, Medline, and Science Direct databases using the keywords ‘sperm proteomics’ and ‘male infertility’. We also reviewed the relevant cross references of retrieved articles and included them in the review process. Articles written in any language other than English were excluded.ResultsOf 575 articles identified, preliminary screening for relevant studies eliminated 293 articles. At the next level of selection, from 282 studies only 80 articles related to male infertility condition met the selection criteria and were included in this review.ConclusionIn this molecular era, sperm proteomics has created a platform for enhanced understanding of male reproductive physiology as a potential tool for identification of novel protein biomarkers related to sperm function in infertile men. Therefore, it is believed that proteomic biomarkers can overcome the gaps in information from conventional semen analysis that are of limited clinical utility.
Systematic review of antioxidant types and doses in male infertility: Benefits on semen parameters, advanced sperm function, assisted reproduction and live-birth rate Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Ahmad Majzoub, Ashok Agarwal ObjectiveTo explore the current evidence concerning the effect of oral antioxidant supplementation on various male fertility outcomes, as antioxidants are widely available compounds that are commonly used for the treatment of male infertility.Materials and methodsPubMed, Medline and Cochrane electronic databases were searched according to a modified Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) guidelines looking for studies investigating the effect of antioxidant therapy on infertile men. The studies were explored looking for antioxidants: (i) types and doses; (ii) mechanism of action and rationale for use; and (iii) effect on the different outcome measures reported.ResultsIn all, 26 studies reported a significant positive effect of antioxidant therapy on basic semen parameters, advanced sperm function, outcomes of assisted reproductive therapy, and live-birth rate. Vitamin E, vitamin C, carnitines, N-acetyl cysteine, co-enzyme Q10, zinc, selenium, folic acid and lycopene were most commonly used. The vitamins’ mechanism of action and reported doses is presented in Tables 1 and 2.ConclusionAntioxidants generally have a favourable effect on male fertility. Further studies are needed to identify the optimal antioxidant regimen that can be used safely and efficiently in clinical practice.
Advances in sperm retrieval techniques in azoospermic men: A systematic review Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Rupin Shah, Chirag Gupta ObjectiveTo evaluate various methods of operative sperm retrieval in men with non-obstructive azoospermia (NOA) and to determine the optimal surgical approach in terms of effectiveness, morbidity, and complications.Materials and methodsPubMed and Cochrane databases were searched to identify five recent reviews and meta-analyses evaluating outcomes for sperm retrieval in men with NOA.Results and ConclusionMicro-TESE is the most efficient method for retrieving sperm but requires special expertise and can be traumatic for the testes. Conventional biopsies are twice more likely to retrieve sperm than fine-needle aspiration. Testicular aspiration performed by multiple passes into the testis is traumatic and is not efficient for sperm retrieval. Needle-aspiration biopsy and open real-time testicular mapping by the single seminiferous tubule technique can offer less traumatic methods for sperm retrieval, which can be tried before proceeding to micro-TESE. The first attempt at sperm retrieval is the best chance the patient has and should combine various techniques sequentially to give the highest chance of success with the least morbidity.
Chromosomal abnormalities in infertile men with azoospermia and severe oligozoospermia in Qatar and their association with sperm retrieval intracytoplasmic sperm injection outcomes Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Mohamed M. Arafa, Ahmad Majzoub, Sami S. AlSaid, Walid El Ansari, Abdulla Al Ansari, Yara Elbardisi, Haitham T. Elbardisi ObjectiveTo study the types and incidence of chromosomal abnormalities in infertile men with azoospermia and severe oligozoospermia in Qatar, and to compare the hormonal changes, testicular sperm retrieval rate, and intracytoplasmic sperm injection (ICSI) outcome between patients with chromosomal abnormalities and patients with idiopathic infertility.Patients and methodsThis study involved the retrospective chart review of 625 infertile male patients attending an academic tertiary medical centre in Qatar. Retrieved information included data on medical history, family history, clinical examination, semen analysis, initial hormonal profiles, and genetic studies, ICSI, and sperm retrieval results.ResultsThe incidence of chromosomal abnormalities was 9.59% (10.6% amongst Qatari patients, 9.04% amongst non-Qataris). About 63.6% of the sample had azoospermia, of whom 10.8% had chromosomal abnormalities. Roughly 36.4% of the sample had oligozoospermia, of whom 7.5% had chromosomal abnormalities. There were no differences between patients with chromosomal abnormalities and those with idiopathic infertility for demographic and infertility features; but for the hormonal profiles, patients with idiopathic infertility had significantly lower luteinising hormone and follicle-stimulating hormone values. For ICSI outcomes, patients with chromosomal abnormalities had a significantly lower total sperm retrieval rate (47.4% vs 65.8%), surgical sperm retrieval rate (41.2% vs 58.1%), and lower clinical pregnancy rate (16.7% vs 26.6%) when compared to the idiopathic infertility group.ConclusionThe incidence of chromosomal abnormalities in Qatar as a cause of severe male infertility is within a similar range as their prevalence internationally.
Systematic review of hormone replacement therapy in the infertile man Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Amr El Meliegy, Ahmad Motawi, Mohamed Ahmed Abd El Salam ObjectivesTo highlight alternative treatment options other than exogenous testosterone administration for hypogonadal men with concomitant infertility or who wish to preserve their fertility potential, as testosterone replacement therapy (TRT) inhibits spermatogenesis, representing a problem for hypogonadal men of reproductive age.Materials and methodsWe performed a comprehensive literature review for the years 1978–2017 via PubMed. Also abstracts from major urological/surgical conferences were reviewed. Review was consistent with the Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) criteria. We used Medical Subject Heading terms for the search including ‘testosterone replacement therapy’ or ‘TRT’ and ‘male infertility’.ResultsIn all, 91 manuscripts were screened and the final number used for the review was 56. All studies included were performed in adults, were written in English and had an abstract available.ConclusionsExogenous testosterone inhibits spermatogenesis. Hypogonadal men wanting to preserve their fertility and at the same time benefiting from TRT effects can be prescribed selective oestrogen receptor modulators or testosterone plus low-dose human chorionic gonadotrophin (hCG). Patients treated for infertility with hypogonadotrophic hypogonadism can be prescribed hCG alone at first followed by or in combination from the start with follicle-stimulating hormone preparations.
Review of the role of robotic surgery in male infertility Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Mohamed Etafy, Ahmet Gudeloglu, Jamin V. Brahmbhatt, Sijo J. Parekattil ObjectivesTo present the current state of the art in various robot-assisted microsurgical procedures in male infertility and review the latest literature, as the technology in infertility procedures has substantially developed since the incorporation of the Vinci® robotic platform (Intuitive Surgical, Inc., Sunnyvale, CA, USA).Materials and methodsThe search strategy in this review was conducted in accordance with Cochrane guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A search strategy was conducted in MEDLINE, PubMed and the Cochrane electronic databases (from 2000 to present) to identify studies that included both robotic and male infertility.ResultsIn all, 23 studies were found, 12 of which met our inclusion criteria. Articles were excluded if the study did not include both male infertility and robotics.ConclusionsRobotic assistance for microsurgical procedures in male infertility appears to be safe and feasible. It has several advantages including elimination of tremor, multi-view magnification, additional instrument arms, and enhanced dexterity with articulating instrument arms. It also has a short learning curve with a small skin incision. However, larger, prospective studies are needed to establish the clinical benefits over standard microsurgery.
Varicocele management for infertility and pain: A systematic review Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Scott D. Lundy, Edmund S. Sabanegh Despite being first described two thousand years ago, the varicocele remains a controversial multifaceted disease process with numerous biological consequences including infertility, hypogonadism, and chronic orchidalgia. The underlying mechanisms remain poorly understood and likely include hypoxia, oxidative stress, hyperthermia, anatomical aberrations, and genetics as primary components. Despite a high prevalence amongst asymptomatic fertile men, varicoceles paradoxically also represent the most common correctable cause for male infertility. In this systematic review we discuss the rich historical aspects of the varicocele and the contemporary data regarding its clinical manifestations. We performed a systematic literature review with the goal of comparing outcomes and complication rates of each of the major surgical approaches as they relate to infertility and pain. We performed a Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-compliant systematic literature review for manuscripts focused on varicocele and its biological consequences. We identified 112 studies suitable for qualitative analysis and included 56 of these for quantitative analysis, with an emphasis on infertility and chronic pain outcomes. Taken together, the clinical work to date suggests that the highest fertility rates and the lowest complication rates are associated with the microsurgical subinguinal surgical approach to varicocelectomy. In all, 26–40% of patients undergoing varicocelectomy will successfully achieve short-term spontaneous pregnancy, and up to 90% of all patients undergoing varicocelectomy for pain will have improvement and/or resolution of their symptoms. Taken together, the data support an ongoing role for varicocelectomy in both of these clinical arenas.
Spermatogonial stem cell transplantation and male infertility: Current status and future directions Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Connor M. Forbes, Ryan Flannigan, Peter N. Schlegel ObjectiveTo summarise the current state of research into spermatogonial stem cell (SSC) therapies with a focus on future directions, as SSCs show promise as a source for preserving or initiating fertility in otherwise infertile men.Materials and methodsWe performed a search for publications addressing spermatogonial stem cell transplantation in the treatment of male infertility. The search engines PubMed and Google Scholar were used from 1990 to 2017. Search terms were relevant for spermatogonial stem cell therapies. Titles of publications were screened for relevance; abstracts were read, if related and full papers were reviewed for directly pertinent original research.ResultsIn all, 58 papers were found to be relevant to this review, and were included in appropriate subheadings. This review discusses the various techniques that SSCs are being investigated to treat forms of male infertility.ConclusionsEvidence does not yet support clinical application of SSCs in humans. However, significant progress in the in vitro and in vivo development of SSCs, including differentiation into functional germ cells, gives reason for cautious optimism for future research.
Microscopic subinguinal varicocelectomy in 100 consecutive cases: Spermatic cord vascular anatomy, recurrence and hydrocele outcome analysis Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Ahmed M. Al-Kandari, Abdulnasser Khudair, Abdelghaffar Arafa, Fouad Zanaty, Ahmed Ezz, Mohamed El-Shazly ObjectiveTo evaluate the detailed vascular anatomy of the spermatic cord during subinguinal microscopic varicocelectomy and to assess the outcome of the cases with regard to varicocele recurrence and hydrocele formation.Patients and methodsIn all, 100 varicocele cases including 74 left-sided and 26 bilateral, comprising 126 spermatic cord units with clinically palpable varicoceles underwent microscopic subinguinal varicocelectomy. Detailed description of vascular anatomy of the spermatic cords was reported. The number of spermatic, cremasteric, and inguinal veins was recorded. A record of testicular arteries and lymphatics was noted. Testicular delivery was done in all the cases and assessment of the gubernacular veins was reported. The patients underwent clinical evaluation, as well as scrotal Doppler ultrasonography, to detect varicocele recurrence and hydrocele formation. The mean (range) postoperative evaluation period was 6 (3–12) months.ResultsThe mean number of spermatic veins was 14 on both sides. The mean number of spermatic arteries on both sides was 1.3. For lymphatics, the mean number was around three on both sides. The gubernacular veins were noted in 75% of the cases on the left side (mean number of 1.2) and in 85% on the right-side, (mean number of 1). The mean number of cremasteric veins on the left and right sides was 1.4 and 1.2, respectively. Finally, inguinal floor vessels were noted in 9% on the left-side and were not seen in the right-side cases. The incidence of varicocele recurrence was 2% and for hydrocele that was not clinically significant was 0.07%.ConclusionMicroscopic subinguinal varicocelectomy accurately evaluated the detailed vascular anatomy of the spermatic cord, achieving excellent surgical outcome with minimal varicocele recurrence and hydrocele formation. Microscopic subinguinal varicocelectomy should be the ‘gold standard’ for varicocelectomy.
Role of varicocele treatment in assisted reproductive technologies Publication date: March 2018 Source:Arab Journal of Urology, Volume 16, Issue 1 Author(s): Mehmet G. Sönmez, Ahmet H. Haliloğlu ObjectiveIn this review, we investigate the advantage of varicocele repair prior to assisted reproductive technologies (ART) for infertile couples and provide cost analysis information.Materials and methodsWe searched the following electronic databases: PubMed, Medline, Excerpta Medica Database (Embase), Cumulative Index to Nursing and Allied Health Literature (CINAHL). The following search strategy was modified for the various databases and search engines: ‘varicocele’, ‘varicocelectomy’, ‘varicocele repair’, ‘ART’, ‘in vitro fertilisation (IVF)’, ‘intracytoplasmic sperm injection (ICSI)’.ResultsA total of 49 articles, including six meta-analyses, 32 systematic reviews, and 11 original articles, were included in the analysis. Bypassing potentially reversible male subfertility factors using ART is currently common practice. However, varicocele may be present in 35% of men with primary infertility and 80% of men with secondary infertility. Varicocele repair has been shown to be an effective treatment for infertile men with clinical varicocele, thus should play an important role in the treatment of such patients due to the foetal/genetic risks and high costs that are associated with increased ART use.ConclusionVaricocele repair is a cost-effective treatment method that can improve semen parameters, pregnancy rates, and live-birth rates in most infertile men with clinical varicocele. By improving semen parameters and sperm structure, varicocele repair can decrease or even eliminate ART requirement.
Complications in robotic urological surgeries and how to avoid them: A systematic review Publication date: Available online 14 December 2017 Source:Arab Journal of Urology Author(s): Rafael Rocha Tourinho-Barbosa, Marcos Tobias-Machado, Adalberto Castro-Alfaro, Gabriel Ogaya-Pinies, Xavier Cathelineau, Rafael Sanchez-Salas ObjectivesTo review the main complications related to the robot-assisted laparoscopic (RAL) approach in urology and to suggest measures to avoid such issues.MethodsA systematic search for articles of the contemporary literature was performed in PubMed database for complications in RAL urological procedures focused on positioning, access, and operative technique considerations. Each complication topic is followed by recommendations about how to avoid it.ResultsIn all, 40 of 253 articles were included in this analysis. Several complications in RAL procedures can be avoided if the surgical team follows some key steps. Adequate patient positioning must avoid skin, peripheral nerve, and muscles injuries, and ocular and cognitive complications mainly related to steep Trendelenburg positioning in pelvic procedures. Port-site access and closure should not be neglected during minimally invasive procedures as these complications although rare can be troublesome. Technique-related complications depend on surgeon experience and the early learning curve should be monitored.ConclusionsAdequate patient selection, surgical positioning, mentorship training, and avoiding long-lasting procedures are essential to prevent RAL-related complications. The robotic surgical team must be careful and work together to avoid possible complications. This review offers several steps in surgical planning to reach this goal.
Critical appraisal of literature comparing minimally invasive extraperitoneal and transperitoneal radical prostatectomy: A systematic review and meta-analysis Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Panagiotis Kallidonis, Bhavan Prasad Rai, Hasan Qazi, Roman Ganzer, Minh Do, Anja Dietel, Evangelos Liatsikos, Nabi Ghulam, Iason Kyriazis, Jens-Uwe Stolzenburg ObjectivesTo systematically review studies comparing extraperitoneal (E-RP) and transperitoneal minimally invasive radical prostatectomy (T-RP).MethodsThe systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in September 2015. Several databases were searched including Medline and Scopus. Only studies comparing E-RP and T-RP (either laparoscopic or robot-assisted approach) were evaluated. The follow-up of the included patients had to be ≥6months.ResultsIn all, 1256 records were identified after the initial database search. Of these 20 studies (2580 patients) met the inclusion criteria. The hospital stay was significantly lower in the E-RP cohort, with a mean difference of −0.30days (95% confidence interval [CI] −0.35, −0.24) for the laparoscopic group and 1.09days (95% CI −1.47, −0.70) for the robotic group (P<0.001). Early continence rates favoured the E-RP group, although this was statistically significant only in the laparoscopic group (odds ratio [OR] 2.52, 95% CI 1.72, 3.70; P<0.001). There was no statistically significant difference between the E-RP and T-RP cohorts for 12-month continence rates for both the laparoscopic (OR 1.55, 95% CI 0.89, 2.69; P=0.12) and robotic groups (OR 3.03, 95% CI 0.54, 16.85; P=0.21). The overall complication and ileus rates were significantly lower in the E-RP cohort for both the laparoscopic and robotic groups. The symptomatic lymphocele rate favoured the T-RP cohort, although this was statistically significant only in the laparoscopic group (OR 8.69, 95% CI 1.60, 47.17; P=0.01).ConclusionThis review suggests that the extraperitoneal approach is associated with a shorter hospital stay, lower overall complication rate, and earlier return to continence when compared to the transperitoneal approach. The transperitoneal approach has a lower lymphocele rate.
The effectiveness of ureteric metal stents in malignant ureteric obstructions: A systematic review Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Panagiotis Kallidonis, Dimitrios Kotsiris, Francesco Sanguedolce, Panteleimon Ntasiotis, Evangelos Liatsikos, Athanasios Papatsoris ObjectiveTo review the literature on the effectiveness, safety and long-term patency of ureteric metal mesh stents (MSs), as a variety of MSs have been used for managing malignant ureteric obstruction over the last three decades.Materials and methodsA systematic review using the search string; Ureter∗ AND (stent OR endoprosthesis) AND metal∗ was conducted on PubMed, Scopus, Web of science and Cochrane Library online databases in May 2016. Prospective, retrospective, and comparative studies including MSs were included. The primary endpoint was the patency rate and the secondary endpoint was complications.ResultsIn all, 324 publications were screened and 31 articles were included in the systematic review; 21 prospective and 10 retrospective studies. These studies reported the effectiveness of specific MSs in population studies, in comparative studies among different MSs, as well as among MSs and JJ stents. It should be noted that all comparative studies were retrospective.ConclusionThe experiences with vascular MSs, such as the Wallstent™ (Boston Scientific/Microvasive, Natick, MA, USA), were related to high occlusion rates, due to endoluminal hyperplasia, and long-term disappointing patency. The use of covered MSs designed for the vascular system was also unfavourable. The Memokath 051™ (PNN Medical A/S, Kvistgaard, Denmark) had better patency rates, but also higher migration rates. The long-term results were acceptable and rendered the Memokath 051 as a viable option for the management of malignant ureteric obstruction. The Uventa™ (Taewoong Medical, Seoul, Korea) and Allium™ (Allium Medical Solutions Ltd, Caesarea, Israel) MSs, specifically designed for ureteric placement, provided promising results. Nevertheless, the wide acceptance of these MSs would require well-designed clinical studies and long-term follow-up.
A prospective randomised double-blind placebo-controlled trial to assess the effect of diuretics on shockwave lithotripsy of calculi Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Sagar Sabharwal, L. Jeyaseelan, Arabind Panda, Lionel Gnanaraj, Nitin S. Kekre, Antony Devasia ObjectiveTo assess the effect of diuretics with shockwave lithotripsy (SWL) on the treatment of renal and upper ureteric calculi.Patients and methodsAdult patients with a solitary non-obstructive radio-opaque renal or upper ureteric calculus with normal renal function were included. They were prospectively randomised to receive either SWL with placebo or SWL with diuretics (40mg parenteral furosemide) in a double-blind manner with a sample size of 48 patients in each arm. The primary outcomes were the SWL success and failure rates. The secondary outcomes were the number of shocks and sessions.ResultsComplete fragmentation was achieved in 89.6% of the patients in the furosemide arm as compared to 81.3% in the placebo arm. Clearance was achieved in 77.1% of the patients in the furosemide arm as compared to 70.8% in the placebo arm. The number of shocks and the number of sessions were higher in the placebo arm. These differences were not statistically significant.ConclusionThe use of diuretics along with SWL treatment of renal and upper ureteric calculi does not show a statistically significant improvement in fragmentation or clearance.
Ultra-mini-percutaneous nephrolithotomy (PCNL) versus standard PCNL: A randomised clinical trial Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Ramin Haghighi, Hossein Zeraati, Maryam Ghorban Zade ObjectiveTo assess the effectiveness and advantages of ultra-mini-percutaneous nephrolithotomy (UM-PCNL) versus standard PCNL (S-PCNL), as one of the most important differences between the various PCNL techniques is the size of the renal access, which contributes to the broad spectrum of complications and outcomes.Patients and methodsThis clinical randomised trial was conducted in 2016. In all, 70 patients with renal or upper ureteric stones of 10–20 mm in diameter, who were candidates for PCNL, were divided equally into two groups. Group A, underwent UM-PCNL using a 9.8-F ureteroscope through a 16-F sheath; and Group B, underwent S-PCNL using a 24-F nephroscope through a 30-F sheath. The stones were fragmented by pneumatic lithotripsy. Any perioperative complications and need for analgesia were recorded, and postoperative pain was assessed in both groups using a visual analogue scale (VAS).ResultsThere were statistically significant differences in postoperative haemoglobin values, haemoglobin drop, transfusion rate, duration of hospitalisation and postoperative VAS pain score between the groups (P < 0.05). There were no significant differences in operation time, need for auxiliary procedures or stone-free rate.ConclusionA minimally invasive UM-PCNL using a 9.8-F ureteroscope can play an important role in the treatment of symptomatic renal and upper ureteric stones of <20 mm in diameter with lesser blood loss, duration of hospitalisation, need of transfusion, and postoperative pain compared with S-PCNL.
Bilateral same-session ureterorenoscopy: A feasible approach to treat pan-urinary stone disease Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Bora Özveren, Murat Tugrul Eren, Hakan Özveri, Uğur Altuğ, Ahmet Şahin ObjectivesTo assess treatment effectiveness and safety of bilateral same-session ureterorenoscopy (BSSU) for the management of stone disease involving the entire urinary system.Patients and methodsWe reviewed the records of 64 patients who underwent BSSU for the treatment of bilateral ureteric and/or kidney stones. Size, number, location per side, and the total burden of stones were recorded. Data on stenting, lithotripsy, and stone retrieval, and details of hospital stay and operation times were investigated. Treatment results were assessed using intraoperative findings and postoperative imaging. The outcome was considered successful in patients who were completely stone-free or who had only residual fragments of ≤2 mm.ResultsThe outcome was successful in 82.8% of the patients who received BSSU (54.7% stone-free and 28.1% insignificant residual fragments). The success rate per renal unit was 89.8%. There were no adverse events in 73.4% of the patients. The most common intraoperative complication was mucosal injury (36%). The complications were Clavien–Dindo Grade I in 9.4% and Grade II in 7.8%. Grade IIIa and IIIb (9.4%) complications required re-treatments. Statistical evaluation showed no association between complication grades and stone, patient, or operation features. Stone burden had no negative impact on BSSU results. The presence of impacted proximal ureteric stones was significantly related to unsuccessful outcomes.ConclusionBSSU is safe and effective for the management of bilateral urolithiasis. BSSU can prevent recurrent surgeries, reduce overall hospital stay, and achieve a stone-free status and complication rates that are comparable to those of unilateral or staged bilateral procedures.
Trends of intervention for paediatric stone disease over the last two decades (2000–2015): A systematic review of literature Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Amelia Pietropaolo, Silvia Proietti, Patrick Jones, Karan Rangarajan, Omar Aboumarzouk, Guido Giusti, Bhaskar K. Somani ObjectiveTo ascertain the publication trends of interventions for paediatric kidney stone disease (KSD) we conducted a systematic review of literature over the last 16 years.Patients and methodsWith a rise of paediatric KSD and related interventions, a systematic review using PubMed was done over the last 16 years for all published papers on ‘Paediatric stone disease intervention – ureteroscopy (URS), shockwave lithotripsy (SWL), percutaneous nephrolithotomy (PCNL), open stone surgery, and laparoscopic stone surgery’. The search was limited to English language articles with a published abstract, whilst case reports, animal and laboratory studies, were excluded. We also analysed the data in two time periods, period-1 (2000–2007) and period-2 (2008–2015).ResultsDuring the last 16-years, 339 papers were published on paediatric stone disease intervention on PubMed. This included papers on URS (95), PCNL (97), SWL (102), open stone surgery (34) and laparoscopic stone surgery (11). During period-1 and period-2 there were 30 and 65 papers on URS, 16 and 81 papers on PCNL, 33 and 60 papers on SWL, nine and 25 papers on open surgery, respectively. When comparing the two periods, there were 92 published papers for all interventions in period-1 and this had risen almost threefold to 247 papers in period-2.ConclusionsOur systematic review shows that intervention for KSD in the paediatric age group has risen over the last 8 years. Whilst URS, SWL, open surgery and laparoscopic surgery have all doubled, PCNL has risen fivefold reflecting an increase in the new minimally invasive PCNL techniques.
Comparison of interrupted- and continuous-suture urethroplasty in tubularised incised-plate hypospadias repair: A prospective study Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Archika Gupta, Rajesh Gupta, Punit Srivastav, Ankush Gupta ObjectiveTo compare the effect of interrupted- and continuous-suture urethroplasty on complication rates in Snodgrass tubularised incised-plate (TIP) hypospadias repair.Patients and methodsThis was a prospective randomised study comprising 100 boys (age range 1–5 years) with primary subcoronal, distal- and mid-penile hypospadias who underwent repair from October 2010 to March 2015 in a tertiary care hospital. Boys with glanular, recurrent, and proximal hypospadias were excluded from the study. The boys were prospectively randomised into two groups: Group A, comprised 50 boys who underwent interrupted subcuticular suture Snodgrass TIP urethroplasty; and Group B, comprised 50 boys who underwent continuous subcuticular suture Snodgrass TIP urethroplasty. Outcomes were assessed in terms of complication rates and aesthetic appearance during follow-up.ResultsThere was no significant difference in the occurrence of complications between the groups. There were 21 complications, with 10 occurring in Group A and 11 in Group-B. Urethrocutaneous fistula was the most common complication in both groups (six in Group A and seven in Group B), the fistulae were <2 mm in nine patients and 3–5 mm in the remaining four. Partial glans dehiscence occurred in one patient in each group. One patient from each group also had superficial wound infection, meatal stenosis and urethral stricture respectively, all of which were managed conservatively. The resultant urinary stream was single and good in all patients of both groups.ConclusionsThe type of suture technique had no significant effect on complication rates after Snodgrass hypospadias repair and thus the choice of technique depends on surgeon preference.
Is transurethral incision better than upper pole partial nephrectomy for management of duplex system ureterocoele diagnosed in the first year of life? Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Amr Hodhod, Yasser A. Noureldin, Mohamed El-Sherbiny ObjectiveTo compare the outcomes of transurethral incision (TUI) and upper pole partial nephrectomy (PN) in patients with duplex system ureterocoele (DSU).Patients and methodsWe retrospectively reviewed the medical charts of patients who presented with DSU in the first-year of life and were managed with either TUI or PN. Patients’ demographics, ultrasonography examinations, voiding cystourethrogram studies, and dimercaptosuccinic acid scans were reviewed. Also, the postoperative vesico-ureteric reflux status and febrile urinary tract infection occurrences, and subsequent surgical interventions were identified. The outcomes for the DSU location (intravesical vs extravesical) were compared.ResultsBetween January 1995 and September 2015, 44 patients underwent TUI (31 patients) or PN (13). The TUI patients presented at a median age of 1.1months and were followed-up for a median of 47.4months, whilst those who underwent PN presented at a median age of 1.06months and were followed-up for a median of 44.23months. Postoperatively, in the TUI group, four of 15 units had improved renal function and 11 units had stable function. In the PN group, five of nine units had stable renal function and the remaining four had worsened function (P=0.019). Furthermore, 15 of the 31 patients (48%) in the TUI group required second interventions compared with one of 13 patients in the PN group (P=0.01). There was no significant difference between the outcomes of intravesical and extravesical DSUs after TUI and PN.ConclusionThis study shows significant renal function preservation with TUI compared to PN. However, secondary surgical interventions were higher with TUI.
Role of urethral plate and fossa navicularis biopsies in the detection of balanitis xerotica obliterans in boys undergoing redo hypospadias repair Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Mohamed Sultan, Mohamed El-Shazly, Eid Elsherif, Sheren Younes, Mohamed Selim ObjectivesTo evaluate the presence of balanitis xerotica obliterans (BXO), clinically and pathologically, in the urethra of boys with failed previous hypospadias repair and where surgical management was planned.Patients and methodsBetween February 2010 and March 2015, boys with failed distal penile hypospadias repair who were planned for surgical management were evaluated for the presence of clinical and pathological evidence of BXO. Samples were obtained from the urethral plate and fossa navicularis, after obtaining informed consent and ethical approval. The samples were fixed, sectioned, and haematoxylin and eosin stained for light microscopic examination.ResultsIn all, 157 boys were enrolled in our study, with a mean (SD) age of 6.4 (2.8)years. All the boys had a history of failed hypospadias repair surgeries (once or more). The presentation was fistula in 34 boys (21.7%), meatal stenosis in 45 (28.7%), urethral stricture in 28 (17.8%), and total dehiscence in 50 (31.8%). BXO was detected clinically in 46 boys (29.3%). The total number of biopsies taken was 314, of which 124 (39.5%) were pathologically BXO-positive samples. Of the 157 boys, BXO-positive cases were clinically associated with fistula in seven boys (4.5%), meatal stenosis in 18 (10.8%), urethral stricture in seven (4.5%), and total dehiscence in 15 (9.6%). Of the 314 pathological samples, pathologically BXO-positive samples were associated with fistula in 20 samples (6.4%), meatal stenosis in 40 (12.7%), urethral stricture in 22 (7%), and total dehiscence in 42 (13.4%).ConclusionsIn failed hypospadias cases BXO should be considered, especially for cases with multiple failures, meatal stenosis, and total dehiscence. Urethral plate and fossa navicularis biopsies are important in planning a proper approach for subsequent repair.
Day care bipolar transurethral resection vs photoselective vaporisation under sedoanalgesia: A prospective, randomised study of the management of benign prostatic hyperplasia Publication date: December 2017 Source:Arab Journal of Urology, Volume 15, Issue 4 Author(s): Rajeev Sood, T. Manasa, Hemant Goel, Ritesh Kumar Singh, Rajpal Singh, Nikhil Khattar, Praveen Pandey ObjectiveTo conduct a prospective randomised study comparing the safety, effectiveness and treatment outcomes in patients undergoing bipolar transurethral resection of the prostate (bTURP) and photoselective vaporisation of the prostate (PVP) under sedoanalgesia, as sedoanalgesia is a safe and effective technique suitable for minimally invasive endourological procedures and although studies have confirmed that both TURP and PVP are feasible under sedoanalgesia there are none comparing the two.Patients and methodsBetween November 2014 and April 2016, all patients satisfying the eligibility criteria underwent either bTURP or PVP under sedoanalgesia after randomisation. The groups were compared for functional outcomes, visual analogue scale (VAS) pain scores (range 0–10), perioperative variables and complications, with a follow-up of 3months.ResultsIn all, 42 and 36 patients underwent bTURP and PVP under sedoanalgesia, respectively. The mean VAS pain score was <2 at any time during the procedure, with no conversions to general anaesthesia. PVP patients had a shorter operating time [mean (SD) 55.64 (12.8) vs 61.79 (14.2) min, P=0.035], shorter duration of hospitalisation [mean (SD) 14.58 (2.81) vs 19.21 (2.82) h, P<0.001] and a higher dysuria rate when compared to bTURP patients. However, the catheterisation time was similar and both intraoperative and postoperative complications were minimal and comparable. Improvements in the International Prostate Symptom Score, quality of life, prostate volume, maximum urinary flow rate and post-void residual urine volume at 3months were similar in both groups. None of our patients required re-admission or re-operation.ConclusionBoth PVP and bTURP can be carried out safely under sedoanalgesia with excellent treatment outcomes.
