RESUMO

OBJECTIVE: To characterize the bulbospongiosus muscle (BSM) in patients with bulbar urethral strictures. MATERIALS AND METHODS: We studied 21 patients divided into 2 groups: Stricture Group (n = 14; mean age = 62.00 years) with bulbar stricture submitted to open urethroplasty; and Control Group (n = 7; mean age = 60.14 years) with penile strictures (hypospadias cripples, penile cancer and/or penile infection) who were submitted to perineal urethrostomy. Samples of the BSM were dissected and histologic sections were stained by histochemical and immunohistochemical techniques. Histomorphometric analyzes were performed on photomicrographs. Means were statistically compared using the unpaired Student t test and the Mann-Whitney test (P <.05). RESULTS: The etiology of bulbar urethral stricture was idiopathic in 2 cases (14.29%), post-TURP in 6 (42.86%), post open radical prostatectomy in 5 (35.71%) and post open prostatectomy in 1 case (7.14%). The average length of the stricture was 2.08 cm. The only parameter analyzed with significant difference between the groups was the vessels (significant difference between the control group: 5.11 ± 1.98% and stricture group: 3.57 ± 1.32%, P = .0460). The quantitative analysis of collagen (Control Group: 10.63 ± 5.37% and Stricture Group: 10.83 ± 4.55%, P = .9296); diameter of BSM muscle fibers (Control Group: 41.71 ± 14.63 µm and Stricture Group: 40.11 ± 8.59 µm, P = .76 and elastic system fibers (Control Group; 3.83 ± 1.54% and Stricture Group: 5.43 ± 2.90%, P = .2601) showed no significant difference. CONCLUSIONS: Histologic analysis showed a significant decrease of the BSM vessels in urethral stricture, without changes in elastic fibers, collagen, nerves, and muscle fiber diameter. These findings show that the bulbar urethral stricture causes minimal alterations in the structure of the BSM.

RESUMO

OBJECTIVES: To investigate the correlation between the characteristics of urethral stricture and incision scars in patients with urethral stricture and median sternotomy incision. Methods: We identified 368 patients who had undergone internal urethrotomy between January 2014 and December 2017. A total of 49 male patients with a median sternotomy scar and diagnosed with  urethral stricture were retrospectively evaluated. The median sternotomy incision scars were assessed using the Vancouver Scar Scale (VSS) and the patients were divided into 2 groups. Group I consisted of patients with a VSS score of less than 4 points, and those with ≥4 points constituted group II. The groups were compared in terms of age, smoking habit, body mass index, diabetes mellitus, hypertension, urethral stricture etiology, length and localization, and stricture relapse after intervention. RESULTS: The mean total VSS score was 2.0 points in group I and 7.46 points in group II. There was a significant correlation between the VSS total score and the urethral stricture length among the whole study population (correlation coefficient value=0.481; p less than 0.001). The urethral stricture was longer as the VSS score increased. Conclusion: A poorly healed median sternotomy incision scar can predict a poor wound healing in the urethra tissue. Further large scale, multi-center and prospective studies are needed to clarify this relationship.

RESUMO

OBJECTIVE: To determine the frequency of complications related to urethral stricture and identify clinical factors associated with them. METHODS: Of 1851 patients with a suspected diagnosis of urethral stricture referred to a single urologist from 2005 to 2016 were retrospectively reviewed. Clinical variables included complications directly related to urethral stricture at the time of patient presentation, associated signs/symptoms, patient age, stricture length, location, and etiology. Complications considered significant were acute urinary retention or difficult catheterization requiring emergent urologic intervention or renal failure, urosepsis, or urethral abscess directly related to stricture. Patients without complete data were excluded from study. The occurrence of complications was compared in relation to patient age, symptoms, stricture length, location, and etiology using binary logistic regression. RESULTS: Of 1023 patients meeting inclusion criteria, mean age was 48.0 years and mean stricture length was 5.0 cm (1-18). Of 40.6% (415) of patients experienced at least one complication directly related to urethral stricture including acute urinary retention (32.6%), difficult catheterization (16.0%), urethral abscess/urosepsis (5.0%), or renal failure (3.1%). On multivariate analysis, stricture length (cm) (odds ratio [OR] 1.1; 95% confidence interval [CI] 1.1-1.2, P = .01), lack of reported lower urinary tract symptoms (OR 3.8, 95%CI 1.9-7.3, P <.0001), posterior stenosis (OR 3.0, 95%CI 1.3-6.8, P = .01), and trauma-related strictures (OR 1.6, 95% CI 1.1-2.4, P = .02) were associated with complications. Lastly, 7.0% of patients experienced complications deemed to be life-threatening. CONCLUSION: Urethral stricture is frequently a morbid condition. Patients with longer strictures, posterior stenoses, absence of preceding lower urinary tract symptoms and traumatic strictures are at highest risk for complications related to urethral stricture and should likely be directed toward more definitive treatment.

RESUMO

Introduction: Incidence of urethral stricture recurrence ranges between 2% to 36.4% with 75% occurring within the first 6 months of surgery. Hence, they need to identify the predictors of recurrence following urethroplasty. Methods: This is a retrospective study involving patients that had urethroplasty from January 2008 to December 2017. Patients' records were reviewed. Analyzed data were for patients with a minimum follow up of one year from the time of urethroplasty and included aetiology of urethral stricture, presence of suprapubic cystostomy, prior urethral dilatation, urine M/C/S, site of urethral stricture, length of urethral stricture, type of urethroplasty, level of training of the surgeon, type of urethral stent used and duration of stenting. Analysis was done using SPSS version 23. P-value of < 0.05 was considered significant. Results: Eighty seven urethroplasties were done, from January 2008 to December 2017. However, only records of 44 patients were accessible. Twenty patients completed duration of follow up ≥ one year. Urethral stricture recurrence was defined as resurgence of Lower Urinary Tract Symptoms (LUTS) within one year. Median age of the patients was 39.5 (± 19) years. Urethral stricture recurrence rate was 25% with mean time to recurrence from urethroplasty of 5.3 (±3) months. The use of preoperative suprapubic catheter (SPC) for urinary diversion as well as urethroplasties performed by the consultants had a lower incidence of recurrence. Conclusion: This study found urethral stricture recurrence of 25%. The level of training of surgeon vis-à-vis the expertise and experience seems to be an important factor, though not statistically significant in determining the outcome of urethroplasty.

RESUMO

OBJECTIVE: To evaluate the presenting complications of patients to reconstructive urologists after masculinizing gender affirming genital reconstructive surgery (GRS) performed elsewhere. METHODS: We identified patients who underwent revision surgery by one of the co-authors for sequelae of masculinizing GRS. We reviewed patient demographics, medical history, details of prior GRS, and complications from GRS. Specific attention was paid to the presence of the following: suprapubic tube dependence, vaginal remnant, urethrocutaneous fistula (UCF) within the fixed urethra (pars fixa), UCF in the phallic urethra, phallic urethral stricture, meatal stenosis, and anastomotic urethral stricture. Statistical analysis was performed using the Fisher's exact test to determine differences in presenting symptoms by GRS. RESULTS: Fifty-five patients who had reconstructive surgery for complications from masculinizing GRS from September 2004 to September 2017 were identified. The median age at surgical correction was 33 years. Fifteen (27%) patients had prior metoidioplasty and 40 (73%) had prior phalloplasty. The median time from date of GRS to presentation to a reconstructive urologist was 4 months. Urethral strictures (n = 47, 86%) were the most common indication for subsequent surgery, followed by urethrocutaneous fistulae (n = 31, 56%) and vaginal remnant (n = 26, 47%). The majority of patients presented with 2 or more simultaneous complications (n = 40, 73%). CONCLUSION: There are several common presenting urologic complications after masculinizing GRS. Patients may present to reconstructive urologists early after GRS performed elsewhere. The long-term outcomes of GRS deserve further study.

RESUMO

Background: Excision and primary anastomotic (EPA) urethroplasty remains the gold standard definitive treatment for short urethral stricture disease. For patients, postoperative erectile function and quality of life are the main goals of the surgery. Patient-reported outcome measures (PROMs) are therefore of major importance. Objective: The objective of this study was to prospectively analyse functional outcomes and patient satisfaction. Design Settings and Participants: We prospectively evaluated 47 patients before and after EPA from August 2009 until February 2017. The first follow-up visit occurred after a median of 2.2 months (n = 47/47), with the second and third follow-ups occurring at a median of 8.5 months (n = 38/47) and 20.2 months (n = 31/47). Before surgery and at each follow-up visit, the patients received five questionnaires: the International Prostate Symptom Score (IPSS), the International Prostate Symptom Score with the Quality of Life (IPSS-QOL) score, the Urogenital Distress Inventory Short Form (UDI-6) score, the International Index of Erectile Function-5 (IIEF-5) score, and the ICIQ-Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTS-QOL) score. Surgical Procedure: Surgery was performed in all cases using the same standardized EPA technique. Outcome Measurements and Statistical Analysis: Voiding symptoms, erectile dysfunction, and quality of life were analysed using paired sample t-tests, with a multiple-testing Bonferroni correction. Any requirement for instrumentation after surgery was considered treatment failure. Results and Limitations: Patients with mild or no baseline erectile dysfunction showed significant decline in erectile function at first follow-up (mean IIEF-5 of 23.27 [standard deviation; SD: 2.60] vs. 13.91 [SD: 7.50]; p=0.002), but this had recovered completely at the third follow-up (IIEF-5: 23.25 [SD: 1.91]; p=0.659). Clinically significant improvements were noted in IPSS, IPSS-QOL-score, UDI-6-score, and ICIQ-LUTS-QOL-score at the first follow-up (p<0.0001). These improvements remained significant at the second and third follow-ups (p<0.0001) for all PROMs. Three of the patients experienced stricture recurrence. The main limitations of this study were incomplete questionnaires, loss to follow-up, and low number of patients. Conclusions: EPA results in an initial decline in erectile function, but full recovery occurred at a median of 20 months. Voiding improved significantly, and a major improvement in quality of life was noted, which persisted for up to 20 months after surgery. Patient Summary: This study showed the importance of patient-reported outcome measures in indicating the actual outcome of urethral stricture disease surgery.

RESUMO

PURPOSE: Evaluate the main etiologies and clinical characteristics of male urethral stricture disease (USD) in Brazil. METHODS: This multicentric study was performed using retrospective data collected from six Brazilian referral centers of urethral reconstruction. The database comprised data from 899 patients with USD who had undergone surgical treatment from 2008 to 2018. Age, stricture site and primary stricture etiology were identified for each patient. RESULTS: The mean age was 52.13 ± 16.9 years. The most common etiology was iatrogenic (43.4%), followed by idiopathic (21.7%), trauma (21.5%) and inflammatory (13.7%). Of the iatrogenic causes, 59% were secondary to urethral instrumentation (60% by urethral catheterization and 40% by transurethral procedures), 24.8% by other procedures (prostatectomy, radiotherapy, postectomy) and 16.2% by failed hypospadia repairs. Pelvic fracture urethral distraction injuries were responsible for most of the trauma-related strictures (62.7%). When stratified by age, the most common stricture etiology was trauma in the 0-39 years old group (42.8%), idiopathic in the 40-59 years old group (32.4%) and iatrogenic in patients over 60 years old (68%). In regard to the stricture site, 80% presented with an anterior urethral stricture and 20% with a posterior stenosis. In the anterior stenosis group, the most common stricture site was bulbar (39.5%). CONCLUSION: In Brazil, as in many developed countries, the most common cause of urethral stricture diseases is iatrogenic, especially urethral catheterization. These findings emphasize the need of a careful urethral manipulation and a better training of healthcare professionals. Trauma is still responsible for a great proportion of strictures and inflammatory etiologies are now less frequently observed.

RESUMO

OBJECTIVE: The aim of the present study was to investigate genetic effects in the formation of congenital lower urinary tract obstruction (LUTO) comprising posterior urethral valves (PUV), urethral atresia, and urethras with variable degrees of stenosis. METHODS: A classic twin study was performed by assessing LUTO twin pairs from the literature. Furthermore, data regarding 3 previously unreported twin pairs with PUV from University of Bonn, Essen and Wroclaws own in-house databases were added. Both pair- and probandwise concordance rates were calculated and compared for monozygotic (MZ) and dizygotic (DZ) twin pairs. RESULTS: The pairwise concordance rates for all LUTO were 53% (95% confidence interval [CI] 32%-73%) and 17% (95% CI 3%-56%) for MZ and DZ twin pairs, respectively (P = .180). The probandwise concordance rates were 69% (95% CI 51%-83%) and 29% (CI 95% 8%-64%) for MZ and DZ twin pairs respectively (P = .084). The MZ/DZ ratios of the pair- and probandwise concordance rates were 3.1 and 2.4, respectively. CONCLUSION: The present study did not show significant differences in comparisons of concordance rates of MZ and DZ twin pairs, probably due to the small number of twin pairs reported. However, the more than 2-fold higher pair- and probandwise concordance rates for MZ versus DZ twin pairs are very suggestive of a contribution of genetic factors to the development of LUTO.

RESUMO

PURPOSE: To examine the functional survival of the artificial urinary sphincter (AUS) AMS800 in a changing patient population. Because of increasing experience and dexterity of the operating team, we hypothesize that patients with known risk factors nowadays have a better survival of their prosthesis. However, due to a change to a more complex case mix, overall results appear to be worse. MATERIALS AND METHODS: All men who underwent implantation of an AUS between 2001 and 2016 because of urethral sphincter deficiency were retrospectively analyzed. Patients were divided in groups based on date of surgery and number of patients: 2001-2009 (G1), 2010-2013 (G2), 2014-2016 (G3). Baseline characteristics and additional therapies prior to implantation were analyzed in all groups. Risk factors for failure only in G1 and G2. Revision or explantation of the AUS was used as endpoint. Kaplan-Meier analysis was used to calculate survival of the device. RESULTS: A total of 129 patients (mean age 72 ± 9 years) underwent 129 primary implants, and 11 secondary implants. Median follow-up was 5.74 years in G1, 3.26 years G2 and 1.54 years G3. Approximately 25% of the patients in G1 had received adjuvant therapy for prostate cancer and 14% underwent previous surgery for incontinence. In G2, 51 and 55% underwent adjuvant therapy for prostate cancer and previous surgery for incontinence, respectively, G3 was comparable. The overall 50% survival improved in patients with radiotherapy and previous incontinence surgery in G2 as compared to G1. CONCLUSIONS: Despite the more complex patient population, the survival of the AUS did not decrease. In some patient categories, the AUS functional survival is even still improving over the past few years.

RESUMO

PURPOSE: To analyze and compare preoperative patient characteristics and postoperative results in men with stress urinary incontinence (SUI) selected for an adjustable male sling system or an artificial urinary sphincter (AUS) in a large, contemporary, multi-institutional patient cohort. METHODS: 658 male patients who underwent implantation between 2010 and 2012 in 13 participating institutions were included in this study (n = 176 adjustable male sling; n = 482 AUS). Preoperative patient characteristics and postoperative outcomes were analyzed. For statistical analysis, the independent T test and Mann-Whitney U test were used. RESULTS: Patients undergoing adjustable male sling implantation were less likely to have a neurological disease (4.5% vs. 8.9%, p = 0.021), a history of urethral stricture (21.6% vs. 33.8%, p = 0.024) or a radiation therapy (22.7% vs. 29.9%, p = 0.020) compared to patients that underwent AUS implantation. Mean pad usage per day (6.87 vs. 5.82; p < 0.00) and the ratio of patients with a prior incontinence surgery were higher in patients selected for an AUS implantation (36.7% vs. 22.7%; p < 0.001). At maximum follow-up, patients that underwent an AUS implantation had a significantly lower mean pad usage during daytime (p < 0.001) and nighttime (p = 0.018). Furthermore, the patients' perception of their continence status was better with a subjective complete dry rate of 57.3% vs. 22.0% (p < 0.001). CONCLUSIONS: Patients selected for an AUS implantation showed a more complex prior history and pathogenesis of urinary incontinence as well as a more severe grade of SUI. Postoperative results reflect a better continence status after AUS implantation, favoring the AUS despite the more complicated patient cohort.

RESUMO

Mechanical and chemical trauma are a widely accepted theories to explain the pathogenesis of meatalstenosis after newborn circumcision. The aim of the present study was to explore the theory that an exposed glans is prone to meatal stenosis. This was done by a novel investigation of boys who were born with "hooded prepuce", a condition in which the glans is completely exposed. Physical examination, lower urinary tract symptoms, urethral meatus configuration, and surgical procedures of 18 children admitted for routine circumcision, who had congenital hooded prepuce with normally located urethral meatus, were analyzed. The study period was 2013 and 2018. All the cases have been seen because of neonatal circumcision request, but was postponed due to hooded prepuce. The only presenting complaint in children was a cosmetically unattractive appearance. There were no symptoms associated with meatal stenosis, they circumcised in an average of 6 years and non of them required any additional procedure.Conclusion: Meatal stenosis did not occur in cases whose glans penis are naked with hooded prepuce. These findings do not support the default chemical and mechanical trauma theories. Hooded prepuce without any penile anomalies is only a cosmetically unattractive appearance and circumcision can correct this. What is known: • The common theory of meatal stenosis etiology is that the meatus undergoes irritation with chemical/mechanical trauma in the absence of a prepuce after newborn circumcision. • Circumcision is usually postponed in newborns with hooded prepuce. What is new: • We did not notice meatal stenosis in cases whose urethral meatus were not covered with a prepuce congenitally. Ammoniacal dermatitis or mechanical trauma theories may not explain the cause of meatal stenosis. • Hooded prepuce is not a handicap to newborn circumcision. It is just a cosmetic problem and circumcision can solve it.

RESUMO

PURPOSE: The necessity to cease anticoagulation before photoselective vaporization (PVP) surgery remains nonconsensual. We aimed at assessing the efficacy and safety of PVP among high-risk benign prostate hyperplasia (BPH) patients on or off anticoagulation. METHODS: We systematically searched Pubmed, Embase, and Cochrane Library Central Register of Controlled Trials (CENTRAL). 2299 patients from 11 studies were eventually included. Newcastle-Ottawa Scale (NOS) was employed to assess the quality and risk of bias of each study. All statistical analyses were conducted with Review Manager v.5.3 software. RESULTS: Ten parameters (operation time, laser time, blood transfusion, urethral stricture, urinary tract infection, reoperation, dysuria, capsule perforation, catheterization time, and re-catheterization) from patients on or off anticoagulant therapy were collected. The patients without anticoagulants performed better at catheterization time [MD - 0.54, 95% CI (- 0.82, - 0.26), P = 0.96, I2 = 0] with a reduction of 0.54 day than those on anticoagulants. Significant statistical difference was not observed from other parameters. Subgroup analysis, grouped by the power output of PVP systems (80 W, 120 W and 180 W), consistently showed no statistical significant difference except at catheterization time in the 180-W PVP subgroup. CONCLUSION: PVP, a safe and effective option for high-risk BPH patients, work comparably regardless of anticoagulant therapy, despite non-anticoagulant patients have shorter catheterization time. It is implied that the use of anticoagulants might be unnecessary to stop for high-risk BPH patients undergoing PVP for the sake of safety, which certainly requires further investigations to confirm.

RESUMO

PURPOSE: To describe the prevalence and surgical management of coexistent adult acquired buried penis (AABP) and urethral stricture disease. AABP patients often have urinary dribbling with resultant chronic local moisture, infection, and inflammation that combine to cause urethral stricture disease. To date, no screening or surgical management algorithms have been described. METHODS: A multi-institutional retrospective study was conducted of the surgical management strategies for patients with concurrent AABP and urethral stricture disease from 2010 to 2017. AABP patient demographics, physical exam findings, and comorbidities were compared between those with and without stricture disease to suggest those that would selectively benefit from screening for stricture disease. RESULTS: Of the 42 patients surgically managed for AABP, 13 had urethral stricture disease (31.0%). Stricture location was universal in the anterior urethra. Sixty-one percent (n = 8) of strictures were 6 cm or longer and managed prior to AABP repair with Kulkarni urethroplasty. Patients with urethral stricture disease were significantly more likely to have clinically diagnosed lichen sclerosus (p = 0.00019). There was no significant difference in BMI, age, or comorbidities between patients with and without urethral stricture disease. CONCLUSIONS: Extensive anterior urethral stricture is common in patients with AABP. Clinical characteristics cannot predict stricture presence except possibly the presence of lichen sclerosus. Definitive stricture surgical options include extensive Johanson Urethroplasty or Kulkarni Urethroplasty. Kulkarni Urethroplasty prior to AABP repair has the benefits of a single-stage repair, good cosmetic outcome with meatal voiding, and dorsal graft placement to allow safe degloving of the penis in the subsequent AABP repair.

RESUMO

OBJECTIVE:: To identify risk factors for urethral stricture and/or bladder neck contracture after transurethral resection of benign prostatic hyperplasia. MATERIALS AND METHODS:: We performed a retrospective analysis of 402 patients, which underwent a monopolar transurethral resection of the prostate in the urology clinic of Sechenov First Moscow State Medical University for prostatic hyperplasia during the period 2011-2014. Urethral stricture and (or) bladder neck contracture in the postoperative period were diagnosed in 61 (15.27%) patients; 34 patients (8.6%) had urethral stricture, 20 (4.97%) bladder neck contracture, and 7 (1.7%) had a combination of urethral stricture and bladder neck contracture. In 341 of cases (84.73%), no late postoperative complications were observed. A total of 106 of the 341 patients met the inclusion criteria, hence, containing all the information necessary for analysis such as the volume of the prostate, the duration of the surgery, the size of the endoscope, data on concomitant diseases, analysis prostatic secretion, and so on. Thus, two groups were formed. Group 1 (106 patients) is the control group in which urethral strictures and/or bladder neck contractures did not occur in the long-term postoperative period and group 2 (61 patients), in which was observed the formation of these complications. To calculate the statistical significance of the differences for categorical data, Fisher criterion was used. For quantitative variables, in the case of normal data distribution, an unpaired t-test or one-way analysis of variance was used; for data having a distribution different from normal, a Mann-Whitney rank test was used. RESULTS:: Regression analysis established the significance of the influence of four factors on the development of scar-sclerotic changes of urethra and bladder neck: the tool diameter 27 Fr ( p < 0.0001), presence of prostatitis in past medical history ( p < 0.0001), prostate volume ( p = 0.003), and redraining of the bladder ( p = 0.0162). CONCLUSION:: The relationship between the diameter of the instrument, presence of chronic prostatitis in anamnesis, increased volume of the prostate, and repeated drainage of the bladder using the urethral catheter with the risk of developing scar-sclerotic changes in the urethra and/or bladder neck are statistically reliable and confirmed as a result of regression analysis.

RESUMO

We investigated long-term functional changes in the kidney and bladder of patients with posterior urethral valve (PUV) who underwent fetal intervention or postnatal surgery.We retrospectively reviewed the medical records of 28 consecutive patients treated for PUV at our institution. Detailed data on medical and surgical histories, particularly on pre- and postnatal treatment modality, including fetal vesicoamniotic shunt, endoscopic valve ablation, and vesicostomy, were collected and analyzed. Long-term renal function was evaluated based on serum levels of creatinine (sCr), estimated glomerular filtration rate (eGFR), and renal scans. Voiding function was evaluated in urodynamic tests.Vesicoamniotic shunting was performed in 12 (42.8%) patients. Although the mean initial sCr was significantly higher in patients in whom a fetal shunt was placed than in others (2.04 vs 1.17 mg/L, P = .038), the sCr at long-term follow-up was not significantly different between them (0.64 vs 0.40 mg/L, P = .186). The mean maximum detrusor pressure was significantly lower in patients with a fetal shunt than in others (37.7 vs 73.0 cm H2O, P = .019). Postnatal vesicostomy was performed in 14 patients, and primary valve ablation was performed in 13 patients. The mean initial sCr was higher in patients in the vesicostomy group than in the primary valve ablation group (2.08 vs 0.86 mg/L, P = .014). However, no significant differences were found in sCr (0.9 vs 0.3 mg/L, P = .252) or GFR (59.1 vs 68.5 mL/min/1.73 m, P = .338) at long-term follow-up. Bladder capacity was greater and residual urine volume was less in the vesicostomy group than in the primary valve ablation group, but without statistical significance.Vesicostomy is more beneficial in the recovery of renal function and is not inferior in terms of bladder function, even in patients with severe PUV disorder. It is a reliable surgical option that can spare renal function and guarantee adequate bladder function in the long term.

RESUMO

BACKGROUND: The incidence of posterior urethral valve (PUV) is estimated at 1:5000-1:8000 males. It is the most common paediatric urologic urgency and the most common cause of male obstructive uropathy and chronic renal failure in children. The study aimed to describe the experience of Yaoundé gynaeco-obstetrics and paediatric hospital in the management of PUV. METHODS: Retrospectively, medical records were retrieved over a ten year period and all data recorded and analyzed for study objectives. Patients were called and evaluated for outcomes regarding morbidity and mortality. RESULTS: A total of 18 patients all males were managed over the ten year period, given prevalence of 13 cases/100,000 admissions and an admission rate of 2 per annum. The median age at presentation was 22 months and 13 (72.2%) participants presented late. Voiding urethrocystogram was done in all the participants where it showed dilated and elongated posterior urethral valves in 16 (88.9%) of the cases. Endoscopic valve ablation resulted in the relief of obstruction in all but 3 (16.7%) participants that had residual valves and 2 (11.2%) participants that had urethral stenosis. Type I valves were most common in 14 (78.0%) participants. The mean duration of follow up was 34.56 ± 21.47 months. Complications at final follow up were: 10 (55.6%) chronic renal failure, 2 (11.2%) end-stage renal failure. The case fatality rate was 5.6%. CONCLUSION: Many patients present late in our setting with already established complications. There is the need to counsel parents/guardians on the importance of long-term follow up after relief of obstruction.

RESUMO

OBJECTIVE: To assess the association of hypoandrogenism (HA) with urethral stricture disease in a series of patients undergoing urethroplasty at 2 institutions. HA has recently been associated with increased urethral atrophy in artificial sphincter failures and decreased androgen receptors and periurethral vascularity. HA might be an etiologic factor in urethral stricture disease. METHODS: We reviewed the charts in 202 men with anterior urethral strictures between 2011 and 2017. We excluded patients with radiation-induced stricture, previous prostatectomy, previous urethroplasty, pelvic fracture-related strictures, or those on testosterone replacement. We defined HA by a total testosterone of less than 300 ng/dL. We used as age-matched cohort from a national database (National Health and Nutrition Examination Survey), as a reference. Stricture characteristics, such as length, location, and etiology were compared in HA and eugonadal groups. RESULTS: Of 202 men with anterior urethral strictures, we excluded 45. Of the remaining 157 patients, 115 (73%) had preoperative testosterone measurements. Overall, hypoandrogenism (HA) was found in 65 of 115 (57%) men in the urethral stricture group compared with 28% of age-matched men in the national database. Mean stricture length in HA and eugonadal men was 7.2 cm and 4.8 cm, respectively (P = .02). CONCLUSION: HA may be more prevalent and associated with increased disease severity in men with anterior urethral strictures. The relationship between HA and stricture formation and its potential impact on therapeutic outcomes merit further prospective investigation.

RESUMO

PURPOSE: We explored the relation of cycling to urinary and sexual function in a large multinational sample of men. MATERIALS AND METHODS: Cyclists were recruited to complete a survey through Facebook® advertisements and outreach to sporting clubs. Swimmers and runners were recruited as a comparison group. Cyclists were categorized into low and high intensity cyclists. Participants were queried using validated questionnaires, including SHIM (Sexual Health Inventory for Men), I-PSS (International Prostate Symptom Score) and NIH-CPSI (National Institutes of Health Chronic Prostatitis Symptom Index), in addition to questions about urinary tract infections, urethral stricture, genital numbness and saddle sores. RESULTS: Of 5,488 complete survey responses 3,932 (72%) were included in our analysis. On multivariate analysis swimmers/runners had a lower mean SHIM score than low and high intensity cyclists (19.5 vs 19.9 and 20.7, p = 0.02 and <0.001, respectively). No significant differences were found in I-PSS or NIH-CPSI scores, or urinary tract infection history. Cyclists had statistically higher odds of urethral stricture compared to swimmers/runners (OR 2.5, p = 0.042). Standing more than 20% of the time while cycling significantly reduced the odds of genital numbness (OR 0.4, p = 0.006). Adjusting the handlebar higher or even with the saddle had lower odds of genital numbness and saddle sores (OR 0.8, p = 0.005 and 0.6, p <0.001, respectively). CONCLUSIONS: Cyclists had no worse sexual or urinary functions than swimmers or runners but cyclists were more prone to urethral stricture. Increased time standing while cycling and a higher handlebar height were associated with lower odds of genital sores and numbness.

RESUMO

BACKGROUND: Phalloplasty with urethral lengthening is the procedure of choice for female-to-male transgender patients who desire an aesthetic phallus and standing micturition, but is associated with complications, including urethral stricture and fistula formation. Horizontal urethra construction can be accomplished with labia minora flaps covered with additional vascularized layers of vestibular tissue when vaginectomy is performed concomitantly with phalloplasty. However, vaginectomy is not a requisite step in phalloplasty, and some individuals may choose to retain their vagina. In these cases, extra layers of vascularized vestibular tissue are not used for horizontal urethra coverage. This study examined the effects of vaginectomy and the addition of extra layers of vascularized vestibular tissue on phalloplasty complication rates. METHODS: A single-center retrospective study of 224 patients who underwent phalloplasty with urethral lengthening was performed. Patients were sorted into vaginectomy and vaginal preservation cohorts and complication rates were assessed. RESULTS: Of 224 total phalloplasty patients, 215 underwent vaginectomy and nine underwent vaginal preservation. Urethral complications occurred in 27 percent of patients with vaginectomy and in 67 percent of patients with vaginal preservation (OR, 0.18; p = 0.02). Vaginectomy was associated with decreased urethral stricture (OR, 0.25; p = 0.047) and urethral fistula formation (OR, 0.13; p = 0.004). Non-urethra-related complications occurred in 15 percent of vaginectomy patients but were not statistically significant (OR, 3.37; p = 0.41). CONCLUSION: Vaginectomy is associated with a significant decrease in urethral stricture and fistula formation, most likely because vaginectomy affords additional horizontal urethroplasty suture line coverage of labia minora flaps with vascularized vestibular tissue. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

BACKGROUND: To illustrate the 10-year risks of urinary adverse events (UAEs) among men diagnosed with prostate cancer and treated with different types of therapy, accounting for the competing risk of death. METHODS: Prostate cancer is the second most common malignancy among adult males in the United States. Few studies have reported the long-term post-treatment risk of UAEs and those that have, have not appropriately accounted for competing deaths. This paper conducts an inverse probability of treatment (IPT) weighted competing risks analysis to estimate the effects of different prostate cancer treatments on the risk of UAE, using a matched-cohort of prostate cancer/non-cancer control patients from the Surveillance, Epidemiology and End Results (SEER) Medicare database. RESULTS: Study dataset included men age 66 years or older that are 83% white and had a median follow-up time of 4.14 years. Patients that underwent combination radical prostatectomy and external beam radiotherapy experienced the highest risk of UAE (IPT-weighted competing risks: HR 3.65 with 95% CI (3.28, 4.07); 10-yr. cumulative incidence = 36.5%). CONCLUSIONS: Findings suggest that IPT-weighted competing risks analysis provides an accurate estimator of the cumulative incidence of UAE taking into account the competing deaths as well as measured confounding bias.
