Renal Transplantation Enhances the Sildenafil Citrate Effectiveness in Patients with Erectile Dysfunction. A Single-Center Perspective.

OBJECTIVE: To assess the efficacy and safety of Sildenafil citrate in the treatment of ED in (HD) compared to post-RT patients. PATIENTS AND METHODS: A concurrent cohort prospective study to evaluate the efficacy of Sildenafil in the treatment of ED in 24 HD patients (Group A) and 13 patients with persistent ED one-year post-RT (Group B). The initial dose of Sildenafil was 25 mg, increased to 50 mg if there is an adequate response. An Arabic-translated International Index of Erectile Function (IIEF) questionnaire was completed one week before and after Sildenafil treatment. An IIEF erectile function score of 26 or an improvement of at least 10 points for the total IIEF score was considered a favorable response to Sildenafil. RESULTS: Group A included 22 patients with a mean age of 47.32 ± 7.013 years, whereas Group B included 13 patients with a mean age of 56.87 ± 9.612 years. The overall efficacy rate of Sildenafil was 40.9% and 76.9% in groups A and B, respectively. The post-treatment IIEF5-15 score increased from 11.1 ± 5.99 to 12.5 ± 6.41 (p = .458) and from 11.82 ± 7.534 to 21.91 ± 5.700 (p = .002) in groups A and B, respectively. In both groups, the duration of HD had no impact on ED improvement except in the post-RT non-responder subgroup. Hypertension, gastrointestinal symptoms, and flushing were both groups' most common side effects. CONCLUSION: RT could enhance the response to sildenafil in treating patients with ED. The outcome is better in younger post-RT patients with moderate and severe erectile dysfunction and shorter dialysis duration.

Laparo-Endoscopic Single-Site Left Donor Nephrectomy In Patients With Uncommon Renal Vascular Anatomy: Does the Technique Make a Difference?

BACKGROUND: To compare donor and recipient outcomes in patients with renal artery and ante-aortic renal vein vs unusual renal vascular anatomy undergoing laparoendoscopic single-site donor nephrectomy (LESSDN). METHODS: A retrospective chart review of the comparative study of donor and recipient outcomes of LESSDN in donors with venous abnormality (n = 28, group A), arterial abnormality (n = 74, group B), and standard donors (n = 248, group C). RESULTS: From September 2016 to August 2022, 350 left LESSDN were performed. The most common anomalies in group A were the retro-aortic and 2 renal veins in 12 patients each. In group B, 72 and 2 patients had 2 and 3 renal arteries, respectively. Operative and warm ischemia times were significantly longer in donors with vascular anomalies. Moreover, patient creatinine on discharge was significantly higher in arterial anomalies; it was 1.61 ± 0.22 compared with 1.26 ± 0.43 and 1.25 ± 0.32 mg/dL for patients with no anomalies and venous anomalies, respectively (P < .001). However, serum creatinine levels recovered after 1 month and were comparable between the study groups. Recipients, operative time, and vascular anastomosis time were significantly longer in recipients with vascular anomaly. Slow graft function was higher in group B (6.9%) than in the other groups. One-year graft survival rates were 96.4%, 94.6%, and 97.1% (P = .496). CONCLUSION: With increased experience, LESSDN in multiple renal arteries and uncommon venous anatomy cases is feasible and safe. Moreover, it does not influence donor or recipient outcomes.

Erectile function after different techniques of bulbar urethroplasty: does urethral transection make a difference?

PURPOSE: We aimed to compare the impact of urethral transection after different techniques of bulbar urethroplasty on erectile function outcome. MATERIALS AND METHODS: We retrospectively reviewed the records for 245 patients who underwent different urethroplasty techniques for bulbar urethral stricture between February 2013 and January 2021. The comparison between the transecting and non-transecting cohorts included patients' demographics, clinicopathological features of the urethral stricture, post-urethroplasty erectile function, and success of urethroplasty. Outcomes were erectile function status verified by IIEF5-15 score at preoperative, three months, and 12 months post-surgery. We defined Post-urethroplasty ED as a decrease of 5 points or more. RESULTS: The urethroplasty success rate of the entire cohort was 86.9% after a mean follow-up of 45.59 ± 21 months. Out of 245 patients, 18 (7.3%) experienced 90-day complications. Transecting bulbar urethroplasty techniques were performed in 74 patients (30.2%), while non-transecting techniques were performed in 171 patients (69.8%). there were no differences between the cohorts regarding urethroplasty success (87.8% Vs. 86.5%, Mantel-Cox test p = 0.93) or postoperative complications (8.1% Vs. 7%, p = 0.73). Transient ED was evident in the transecting cohort as reported in 8.1% compared to 2.9% for the non-transecting (p = 0.07).Still, but de novo permanent ED was comparable (4.1% Vs. 2.9%, p = 0.65), for transecting and non-transecting, respectively. CONCLUSIONS: Unfortunately, some patients who undergo transecting techniques of bulbar urethroplasty experience transient erectile dysfunction that can improve within the first post- urethroplasty year; however, de novo permanent erectile dysfunction is uncommon after different techniques of bulbar urethroplasty and is not predisposed by urethral transection.

Evaluation of ultrathin semirigid ureteroscopy in terms of efficiency and cost compared to flexible ureteroscopy in treating proximal ureteric stones: a prospective randomized multicenter study.

PURPOSE: To investigate the outcome and cost-effectiveness of ultrathin 6-7.5-Fr semirigid ureteroscopy in treating proximal ureteric stones compared to flexible ureteroscopy. METHODS: Two hundred and twenty patients with a solitary proximal ureteric stone were eligible for ureteroscopy (stone size = 1-2 cm). Patients were randomly subdivided into two groups: Group I included 105 patients who underwent ultrathin semirigid ureteroscopy and group II included 115 patients who underwent flexible ureteroscopy. Both groups were compared regarding successful stone access, operation time, reoperation rates, the financial cost to stone-free, complications, and stone clearance at 4 and 8 weeks. RESULTS: Groups I and II had no significant differences regarding patient demographics, stone criteria, and hospitalization time. In contrast, the mean operative time was significantly longer in group II (p < 0.001). The overall scope-to-stone access rate was 89.5%. It was 87.6% compared to 91.3% (p = 0.32), while the stone-free rate was 81.9% versus 87.8% (p = 0.22) for groups I and II, respectively. Intraoperative and postoperative complications were statistically insignificant between the study groups. The cost/person in Egyptian pounds was 8619 ± 350 in group I, compared to 17,620 ± 280 in group II (p < 0.001); similarly, the cost to attain the stone-free rate was 8950 ± 720 in group I compared to 17,950 ± 500 in group II. CONCLUSION: Ultrathin semirigid ureteroscopy is safe, durable, and considered a cost-effective method for treating upper ureteric calculi compared to the flexible ureteroscopy and could be considered a first treatment option in developing countries.

Long-term effect of sleeve gastrectomy surgery on Hormonal Profile, Semen Parameters and sexual functions of obese infertile men; a prospective observational study.

BACKGROUND: The effect of bariatric surgery on impaired semen parameters, hormonal profile and sexual function remains controversial to some extent. THE CONTEXT AND PURPOSE OF THE STUDY: To look at the long-term effects of sleeve gastrectomy on hormonal profiles, sperm parameters, and sexual function in infertile men with severe obesity. This prospective study included fifty-four obese patients with primary or secondary infertility who were scheduled for sleeve gastrectomy between February 2018 and March 2021. All participants were given a sperm analysis and a serum hormone profile before, 12, and 18 months after surgery. We used the International Index of Erectile Function questionnaire to assess sexual function. RESULTS: There was a significant correlation between weight loss after sleeve gastrectomy and improvement in lipid profile (p < 0.05). No significant detectable effect of post-gastrectomy weight loss on patients with diabetes mellitus, hypertension, or obstructive sleep apnea. As regards the hormonal profile, sex hormone binding globulin, total and free testosterone improved significantly after 12- and 18-months following sleeve gastrectomy. There was a significant increase in sperm count and total sperm number during the follow-up after sleeve gastrectomy (p < 0.05), however, there were no significant changes in other semen parameters. Concerning sexual function, sexual desire, erectile function, and satisfaction improved significantly at 12 and 18 months after surgery. CONCLUSION: Weight loss through sleeve gastrectomy surgery significantly improves testosterone deficiency, sexual performance, and Sperm count in obese infertile men.

RéSUMé: CONTEXTE: L'effet de la chirurgie bariatrique sur l'altération des paramètres du sperme, du profil hormonal et de la fonction sexuelle, reste controversé dans une certaine mesure. Le contexte et le but de l'étude : examiner les effets à long terme de la gastrectomie longitudinale sur les profils hormonaux, les paramètres du sperme et la fonction sexuelle chez les hommes infertiles souffrant d'obésité sévère. Cette étude prospective comprenait 54 patients obèses, atteints d'infertilité primaire ou secondaire, qui devaient subir une gastrectomie longitudinale entre février 2018 et mars 2021. Tous les participants ont eu une analyse de sperme et un profil hormonal sérique avant, puis 12 et 18 mois après la chirurgie. La fonction sexuelle a été évaluée au moyen du questionnaire de l'indice international de la fonction érectile. RéSULTATS: Une corrélation significative était présente entre la perte de poids après la gastrectomie longitudinale et l'amélioration du profil lipidique (p < 0,05). Aucun effet significatif détectable de la perte de poids post-gastrectomie n'a été retrouvé chez les patients atteints de diabète, d'hypertension ou d'apnée obstructive du sommeil. En ce qui concerne le profil hormonal, la globuline liant les hormones sexuelles, la testostérone totale et la testostérone libre se sont significativement améliorées à 12 et 18 mois après la gastrectomie longitudinale. Il y eut une augmentation significative de la numération de spermatozoïdes et du nombre total de spermatozoïdes au cours du suivi après la gastrectomie longitudinale (p < 0,05) ; sans, toutefois, de changements significatifs pour les autres paramètres du sperme. En ce qui a concerné la fonction sexuelle, le désir sexuel, la fonction érectile et la satisfaction se sont considérablement améliorés 12 et 18 mois après la chirurgie. CONCLUSION: La perte de poids due à la chirurgie par gastrectomie longitudinale améliore significativement le taux de testostérone, la performance sexuelle et le nombre de spermatozoïdes chez les hommes infertiles obèses.

Successful Completion of Left Laparoendoscopic Single-Site Donor Nephrectomy in a Patient with Duplicated Inferior Vena Cava: Case Report and Review of Literature.

Duplication of the inferior vena cava is a rare vascular anomaly that increases the complexity of living donor nephrectomy and subsequent transplant. We present the case of a successful left-side laparoendoscopic single-site donor nephrectomy performed in a donor with a duplicated inferior vena cava. The length of the left renal vein was adequate for anastomosis in the recipient, with no late surgical complications at 9 months for both donor and recipient. Duplicated inferior vena cava is not a contraindication for left kidney transplant. Preoperative assessment and planning with computed tomography angiography are essential. Laparoendoscopic single-site donor nephrectomy can be performed safely in patients with duplicated inferior vena cava.

Evaluation of urodynamic pattern in short and long-standing diabetic patients.

PURPOSE: To address the pattern of urodynamic findings in diabetic patients with lower urinary tract symptoms (LUTS), comparing short-standing and long-standing type 2 diabetes mellitus (T2DM). METHODS: A prospective study was conducted on 50 patients presenting with LUTS and a concurrent diagnosis of T2DM, between February 2016 and May 2018. Patients were classified and evaluated according to the duration of diabetes into two groups: short-standing DM (< 15 years, n = 31), and long-standing DM (≥ 15 years, n = 19) groups. The impact of LUTS and quality of life were assessed in female patients using ICIQ-FLUTS and male patients using ICIQ-MLUTS. RESULTS: A total of 50 patients were included in the study. The mean duration of T2DM was 10 ± 0.7 years. The mean age was 56.3 ± 1.2 years, and the mean HbA1c was 7.5 ± 1.2%. Urodynamic evaluation detected significantly higher detrusor overactivity (DO) and increased bladder sensation with the short-standing DM group (35.5 vs. 15.8%, p = 0.01 and 32.3 vs. 5.3%, p = 0.01, respectively). Comparatively, weak, or absent detrusor contractility were more frequent in patients with long-standing DM (52% and 26% respectively p = 0.01). As expected, overflow incontinence and straining during voiding were significantly higher in the long-standing DM group (p = 0.04 and p = 0.03, respectively). Surprisingly, there was no significant correlation between patients presenting with urgency in their voiding diary (subjective) and urodynamic detection of DO (p = 0.07). CONCLUSIONS: There are different patterns in urodynamic characterizations of T2DM. Patients with short-standing DM present more commonly with storage symptoms and detrusor overactivity on urodynamics. Contrastingly, patients with long-standing DM present more frequently with voiding symptoms and detrusor underactivity on urodynamics. Thus, screening for an underactive bladder is advisable in patients with long-standing T2DM.

Value of preoperative ureteral wall thickness in prediction of impaction of ureteric stones stratified by size in laser ureteroscopic lithotripsy.

OBJECTIVES: To evaluate the role of preoperative UWT in the prediction of impaction of ureteral stones stratified according to stone size in ureteroscopic laser lithotripsy. PATIENT AND METHODS: This study included 154 patients submitted to URSL for ureteral stones. Radiological data comprised the presence of hydronephrosis, anteroposterior pelvic diameter (PAPD), proximal ureteric diameter (PUD), and maximum UWT at the stone site. Collected stone characteristics were stone size, side, number, site, and density. RESULTS: The study included 154 patients subjected to URSL. They comprised 74 patients (48.1%) with impacted stones and 80 (51.9%) with non-impacted stones. Patients were stratified into those with stone size ≤ 10 mm and others with stone size > 10 mm. In the former group, we found that stone impaction was significantly associated with higher PAPD, PUD, and UWT. In patients with stone size > 10 mm, stone impaction was related to higher UWT, more stone number, and higher frequency of stones located in the lower ureter. ROC curve analysis revealed good power of UWT in discrimination of stone impaction in all patients [AUC (95% CI) 0.65 (0.55-0.74)] at a cut-off of 3.8 mm, in patients with stone size ≤ 10 mm [AUC (95% CI) 0.76 (0.61-0.91)] at a cut-off of 4.1 mm and in patients with stone size > 10 mm [AUC (95% CI) 0.72 (0.62-0.83)] at a cut-off of 3.0 mm. CONCLUSIONS: Stratifying ureteric stones according to size would render UWT a more practical and clinically-oriented approach for the preoperative prediction of stone impaction.

A Primary Epithelioid Angiosarcoma Arising in a Bilharzial Urinary Bladder: A Reappraisal and Case Report.

BACKGROUND: Angiosarcoma (AS) of the urinary bladder is a very rare and aggressive malignancy with a dismal outcome. CASE REPORT: Here, we report a primary epithelioid angiosarcoma (EAS) of the urinary bladder in a forty-nine-year-old male patient who presented with severe hematuria. Cystoscopic examination revealed hemorrhagic ulcerated bladder mucosa but no definite mass lesions. Intractable hematuria raised the initial clinical impression of idiopathic hemorrhagic cystitis. Analysis of the cystoscopic biopsy revealed features of old bilharzial cystitis, markedly atypical epithelioid endothelial cells arranged as primitive anastomosing vascular structures and expressing vascular markers. The diagnosis of EAS was established. The patient developed intractable severe hematuria, and a radical cystoprostatectomy was performed. The patient was started on chemotherapy but suddenly developed widespread distant metastasis (liver, lung, suprarenal glands, and lymph nodes) and succumbed to death two months after the surgery. CONCLUSION: To the best of these authors' knowledge, we presented the first report of primary EAS arising in a bilharzial bladder. The relevant studies were discussed.

The Outcome of COVID-19 Infection on Kidney Transplantation Recipients in Southern Saudi Arabia: Single-Center Experience.

BACKGROUND: To report the incidence, risk factors, and outcome of severe COVID-19 disease in kidney transplant recipients attending a Saudi hospital at a single center in the Kingdom of Saudi Arabia. METHODS: A retrospective chart-based cohort study involving all kidney transplant recipients tested for COVID-19 in the Armed Forces Hospital Southern Region, KSA. RESULTS: Of 532 kidney transplant recipients who reported to the center, from March 2020 to June 2022, 180 were tested for COVID-19. Of these recipients, 31 (17%) tested positive. Among the 31 positive recipients, 11 were treated at home, 15 were admitted to the noncritical isolation ward, and 5 were admitted to the intensive care unit (ICU). Older age (P = .0001), higher body mass index (P = .0001), and history of hypertension (P = .0023) were more frequent in the COVID-19-positive recipients. Admission to the ICU was more frequent in older recipients (P = .0322) with a history of ischemic heart disease (P = .06) and higher creatinine baseline (P = .08) presenting with dyspnea (P = .0174), and acute allograft dysfunction (P = .002). In the ICU group, 4 (80%) patients required hemodialysis, and 4 (80%) died. CONCLUSIONS: Kidney transplant recipients with COVID-19 could have a higher risk for developing acute kidney injury, dialysis, and mortality than the general population. ICU admission and renal replacement therapy were more evident in older recipients with a history of ischemic heart disease, presenting with shortness of breath (P = .017) and a higher serum creatinine baseline. Acute allograft dysfunction was the independent predictor of mortality among patients admitted to the ICU.

Erectile and voiding function outcomes after buccal mucosa graft urethroplasty for long-segment bulbar urethral stricture: ventral versus dorsal onlay technique.

PURPOSE: To compare the impact of dorsal versus ventral onlay buccal mucosa graft bulbar urethroplasty on postoperative erectile function status. MATERIALS AND METHODS: We retrospectively reviewed the records for 232 patients who underwent dorsal and ventral onlay buccal mucosa graft bulbar urethroplasty from March 2012 to April 2021. Outcomes were urinary and erectile function status as assessed by IIEF5-15 score at preoperative, three months, and 12 months post-urethroplasty. We compared the dorsal and ventral only techniques at the different follow-up visits using difference-in-differences analysis. RESULTS: 165 patients met our inclusion criteria; the overall success rate was 87.9% after a mean follow-up of 52.3 ± 18.5 months. Of the patients, 17.6% experienced a 90-day complication. When comparing dorsal and ventral only techniques, there were no significant differences in terms of success rate (88.3% vs. 87.1%, Mantel-Cox test p = 0.68) or postoperative complications (15.5% Vs. 19.4%, p = 0.3). Likewise, there was no significant difference between both techniques regarding postoperative erectile function as assessed by IIEF5-15 score after three months (26.28 ± 2.53 Vs. 26.37 ± 2.41; p = 0.836) and twelve months (26.88 ± 2.45 Vs. 26.48 ± 1.98; p = 0.532). We detected a post-urethroplasty transient ED in (3.9% vs. 1.6%; p = 0.41), and permanent ED in (1.9% vs. 3.2%; p = 0.6) for dorsal and ventral onlay, respectively. CONCLUSIONS: Onlay Buccal mucosa graft urethroplasty is a highly effective surgery in treating long-segment bulbar urethral stricture. The dorsal and ventral only techniques were comparable regarding urinary and erectile function outcomes. Additionally, both techniques have no significant negative impact on post-urethroplasty erectile function status.

Recurrent Urinary Tract Infection in Living Donor Renal Transplant Recipients and the Role of Behavioral Education Program in Management: A Single-Center Experience.

BACKGROUND: Urinary tract infections (UTIs) are the most prevalent type of kidney transplant (KT) recipients. We aimed to investigate the incidence, causes, and clinical impact of early recurrent UTI post-living donor KT and to examine the role of behavioral education program in management. METHODS: This retrospective cohort chart-review study included all KT recipients with recurrent UTI necessitating hospital admission between September 2017 and August 2021. All patients with recurrent UTI were subjected to behavioral education for a month. RESULTS: UTI was found in 14 of 145 patients (9.6%), with recurrent UTI in 11 (7.6%). A total of 93% of UTIs occurred during the first 6 months post-transplant and represented 52% of KT readmissions during the same period. A total of 64.3% of patients were older than 50 years. The mean (SD) length of hospital stay was 5 (2.5) days, with an equal incidence in both sexes. The most common bacterial isolates in early recurrent UTI were Escherichia coli in 80.9%. Both Extended-spectrum beta-lactamases and multidrug-resistant organisms (resistance in ≥3 drugs) were seen in 82.4% of isolates. Furthermore, the most effective antibiotic was meropenem, with 86.7% effectiveness. A total of 65% of UTIs were managed with a single antibacterial course. A total of 64.3% of patients were older than 50 years. In patients who developed UTI, the mean (SD) serum creatinine was 1.31 (0.52) mg/dL, with a mean increase in serum creatinine of 0.19 mg/dL on having the episodes; at 1 year post-transplant, serum creatinine declined to 1.23 (0.43) mg/dL. Four patients (36%) had no recurrence of UTI after behavioral education. CONCLUSIONS: The multidrug-resistant bacterial isolates account for 82.4% of the UTIs. Therefore, antibiotic prescription should follow the antimicrobial stewardship guidelines. Behavioral education significantly reduced the incidence of recurrent UTI.

Urinary Bladder Traversed by Peritoneal Dialysis Catheter and Discovered Accidently During Living Donor Kidney Transplant: A Case Report and Review of the Literature.

Peritoneal dialysis is a well-established renal replacement therapy for end-stage renal disease. Insertion of a peritoneal dialysis catheter has inherent complication risks. We present a case of a triple-cuff peritoneal dialysis catheter that traversed the urinary bladder on its way to its final destination and was discovered 3 months later during living donor kidney transplant. We observed a 22-year-old male patient on peritoneal dialysis who was admitted for living related kidney transplant. Intraoperatively, we discovered that the well-functioning peritoneal dialysis catheter was inserted through the urinary bladder. Diagnostic intraoperative cystogram and cystoscopy were conducted. Open removal of the peritoneal dialysis catheter and repair of entry and exit sites were performed. The postoperative course was uneventful, and the patient was discharged 11 days postoperatively with a functioning graft. Bladder catheterization before peritoneal dialysis catheter insertion, even in low-risk patients, is mandatory, to avoid bladder perforation. In addition to the case report, we reviewed the pertinent literature.

Endoscopic combined intrarenal surgery in the prone split-leg position versus Galdakao-modified supine Valdivia position for the management of partial staghorn calculi.

OBJECTIVE: To evaluate and compare the outcome of ECIRS in the treatment of partial staghorn renal calculi in both prone split-leg positions versus GMSV positions with regard to; technical aspects, success rate, operative time, complications, safety, and effectiveness of both approaches. PATIENTS AND METHODS: Between October 2018 and August 2021, 66 patients with partial staghorn calculi were enrolled in this prospective comparative study. Patients were randomly divided according to a 1:1 ratio into two groups. Group A included 33 patients who were treated by (ECIRS) in the prone split-leg position, and group B included 33 patients who were treated by (ECIRS) in the Galdakao-modified supine Valdivia (GMSV) position. RESULTS: No significant statistical difference between both groups regarding the mean age (p = 0.448), mean body mass index (BMI) (p = 0.137), mean stone burden (p = 0.435), mean operative time (p = 0.541) and the number of calyces located in branched stones (p = 0.628). The mean hospital stay was 6.71 ± 1.12 days for group A and 6.66 ± 1.10 days for group B patients (p = 0.724). The final SFR was achieved in (29)87.87% and (30)90.9% of group A & B patients, respectively (p = 0.694). No significant difference was detected between both groups in perioperative complication rates. CONCLUSION: ECIRS is safe and effective in treating partial staghorn calculi either in the prone split-leg position or in the Galdakao-modified supine Valdivia position, with comparable outcomes and no statistically significant difference between both positions.

Does Kidney Transplantation Help Young Patients on Dialysis With Erectile Dysfunction? A Single-center Study.

OBJECTIVE: to investigate the effects of a successful KT on EF in male patients with ESRD. MATERIALS AND METHODS: A single-center cross-sectional prospective study to assess the erectile dysfunction in male patients one month before and one year after KT. We adopted a validated, self-administered translated International Index of Erectile Function (IIEF-15) questionnaire. A sub-analysis was performed by categorizing the cohort into 2 age groups: <50 and ≥50 yr. RESULTS: Between September 2017 and February 2021, 68 ESRD patients underwent kidney transplantation (KT), with a mean age of 48.9 ± 12.9 years. Thirty-one patients were below 50 years (Group I). The median hemodialysis duration was 12 months. Sixty-three patients (92.6%) had ED. The mean total IIEF-15 score before and after was 46.8/75 ±12.7 and 55.5 ±13, respectively (P <.001). Forty-six patients (67.6%) reported improved erectile function, 22 (32.4%) did not demonstrate any change, and no patient reported deterioration. Moreover, after KT, sexual desire, orgasm, and overall patient satisfaction improved significantly. Before KT, 83.8% and 100% of groups I and II patients had ED, which dropped to 22.6% and 86.5%, respectively, after KT. IIEF-15 scores improved in both groups. However, the improvement in ED was observed significantly in young patients with mild ED. CONCLUSION: KT positively impacts sexual function and improves erectile dysfunction, especially among young patients. The duration of dialysis before kidney transplantation had no impact on ED improvement after transplantation. The positive effect of transplantation on ED could encourage ESRD patients to undergo KT.

Factors predicting successful sperm retrieval in men with nonobstructive Azoospermia: A single center perspective.

Predicting successful sperm retrieval is essential in counseling infertile men with Azoospermia. Objectives: To assess the predictors of successful sperm extraction in men with nonobstructive Azoospermia. Patients and Methods: A retrospective study included all patients with nonobstructive Azoospermia from January 2018 to May 2019. Subdivided into two groups, group I (negative sperm retrieval) and group II (positive sperm retrieval). Results: A total of 108 patients with a mean age of 36.8 ± 10 years were included. The rate of successful sperm retrieval was 47.2%. Group I included 57 patients (52.8%) with a mean age of 33.98 ± 6.18, and group II included 51 patients (47.2%) with a mean age of 40.04 ± 12.22 (p = 0.008). Follicular stimulating hormone (FSH) levels were significantly higher in group I (18.55 ± 13 vs. 7.97 ± 7.11; p < 0.004). Similarly, in group I, luteinizing hormone was significantly higher (11.4 ± 7.45 vs. 5.9 ± 4.4; p < 0.001). Age and FSH were the independent predictors of successful micro-TESE. Additionally, successful pregnancies were 13.7% of patients, 28.6% of which gave rise to living birth. Conclusion: Patients' age and serum FSH are independent predictors of successful sperm retrieval for infertile men with nonobstructive Azoospermia; young patients with high FSH levels could have little chance of sperm retrieval.

Post-Laparoendoscopic Single-Site Donor Nephrectomy Ipsilateral Testicular Pain, Does Operative Technique Matter? A Single Center Experience and Review of Literature.

Aim: To assess incidence and characteristics of post-laparoendoscopic single-site donor nephrectomy (LESS DN) testicular pain. Materials and Methods: A prospective comparative study of all male donors post-left LESS DN (group A) vs. postopen nephrectomies (group B) was performed at our center. Patients' demographics, perioperative data, and postoperative consultation reports were reviewed. Testicular pain, swelling, numbness, urinary symptoms, and sexual dysfunction were evaluated. Patients with a history of scrotal pathology or surgical procedure were excluded. Pain and tenderness were scored on a standard 10-point scale. Results: From September 2017 to December 2020, 85 and 35 male patients of groups A and B met the evaluation criteria. Ipsilateral testicular pain developed in 11 patients (15.3%) and 2 patients (9.5%) in groups A and B, respectively. In most instances, the pain was mild to moderate in severity, started after 6 ± 2.1 and 4 ± 1.1 days postoperatively in groups A and B, respectively. Six patients in group A were evaluated with transscrotal ultrasonography that showed no abnormalities. All patients in both groups responded well to medical treatment. Conclusions: Post-LESS DN ipsilateral testicular pain is usually mild and self-limited. Preoperative patient education and discussion of the possibility of development of testicular pain and its management should be an integral component of laparoscopic donor nephrectomy informed consent.

Factors Predicting Urethral Stricture Recurrence after Dorsal Onlay Augmented, Buccal Mucosal Graft Urethroplasty.

INTRODUCTION: This study was carried out to identify the predictors of urethral stricture recurrence after dorsal onlay buccal mucosal graft (BMG) urethroplasty. MATERIALS AND METHODS: The medical records of patients with anterior urethral stricture who underwent dorsal onlay BMG urethroplasty at a single tertiary medical center during the period from March 2010 to January 2018 were reviewed. Only patients with ≥2-year follow-up were included. Data regarding patient demographics, clinical characteristics, stricture characteristics, postoperative course, and adverse events were recorded. Kaplan-Meier analysis was used to assess the recurrence-free survival and likelihood of stricture recurrence. Cox regression analysis was used to identify potential independent predictors of stricture recurrence. RESULTS: This study included 266 patients with a mean age of 37.71 years and a mean follow-up period of 49.77 months. From the overall study cohort, 34 (12.8%) reported stricture recurrence and 232 (87.2%) were not. The mean recurrence-free time was 79.93 months and mean time to recurrence was 21.59 months. On multivariate analysis, obesity (hazard ratio (HR): 6.02; 95% conference interval (CI): 1.91, 19.03: p = 0.002), inflammatory aetiology (HR: 9.13; 95% CI: 3.50, 23.81; p < 0.001), prior urethroplasty (HR: 8.81; 95% CI: 3.26, 23.86; p < 0.001), penile stricture location (HR: 3.09; 95% CI: 1.10, 8.71; p = 0.033), and stricture length >4.5 cm (HR: 6.83; 95% CI: 1.69, 27.62; p = 0.007) were the significant independent predictors of stricture recurrence. CONCLUSIONS: Dorsal onlay BMG urethroplasty has a reasonable recurrence-free rate with acceptable postoperative complications. Obesity, inflammatory etiology, prior urethroplasty, penile stricture location, and longer stricture were the factors associated with urethral stricture recurrence.
