Purpose: We sought to characterize sex-stratified differences in bladder management and bladder symptoms and satisfaction after spinal cord injury. Materials and Methods: This study was a prospective, cross-sectional, observational study; eligibility included: age (18 years and acquired spinal cord injury. Bladder management was grouped as (1) clean intermittent catheterization, (2) indwelling catheter, (3) surgery, and (4) voiding. Primary outcome was Neurogenic Bladder Symptom Score. Secondary outcomes were subdomains of the Neurogenic Bladder Symptom Score and bladder-related satisfaction. Multivariable regression was used in sex-stratified models to establish associations between participant characteristics and outcomes. Results: A total of 1,479 participants enrolled in the study. Of the patients 843 (57%) were paraplegic and 585 (40%) were women. Median age and time from injury were 44.9 (IQR 34.3, 54.1) and 11 (IQR 5.1, 22.4) years. Women utilized clean intermittent catheterization at a lower rate (42.6% vs 56.5%) and surgery at a higher rate (22.6% vs 7.0%), especially catheterizable channel creation with or without augmentation cystoplasty (11.0% vs 1.9%). Women had worse measures of bladder symptoms and satisfaction across all outcomes. In adjusted analyses, women and men utilizing indwelling catheters had fewer associated overall symptoms (Neurogenic Bladder Symptom Score), less incontinence, and fewer storage and voiding symptoms. Surgery was associated with fewer bladder symptoms (Neurogenic Bladder Symptom Score) and less incontinence in women, and was also associated with better satisfaction in both sexes. Conclusions: There are significant sex-stratified differences in bladder management after spinal cord injury, which included a much higher use of surgery. Bladder symptoms and satisfaction are worse across all measurements in women. Women have a substantial associated benefit with surgery, while both sexes have fewer bladder symptoms with indwelling catheters compared to clean intermittent catheterization.

Purpose: We assessed the use of conservativemanagement for American Association for the Surgery of Trauma grade V renal trauma in the National Trauma Databank. Materials and Methods: We used data of grade V renal trauma patients in the 2017-2019 National Trauma Databank. Conservative management was defined by the absence of surgical or procedural intervention except for ureteral stent or percutaneous drain placement. We initially analyzed patients who survived to final hospital discharge and reported the percent utilization of conservative management. We then repeated our analysis in the overall grade V population and in all those who did not die in the emergency department. Results: Of 1,474 who survived to discharge, 557 (37.8%) patients were managed conservatively. In the adjusted analysis, penetrating trauma mechanism (OR 0.13, 95% CI 0.09-0.19, P < .001) and receiving transfusion (OR 0.22, 95% CI 0.17-0.29, P < .001) were associated with decreased odds of receiving conservative management. Overall, there were 1,919 patients with grade V injury, of whom 731 (38.1%) were managed conservatively. Mortality rate was 22.8% in those managed conservatively vs 23.8% in those who had intervention. After excluding 110 patients who died in the emergency department, there were 1,809 patients, of whom 625 (34.6%) were managed conservatively. Mortality rate was 22.6% in the operatively managed group and 10.9% in the conservatively managed group. Conclusions: A substantial portion of grade V renal trauma cases were managed successfully without intervention in the National Trauma Databank. Further research is needed to identify radiological phenotypes suitable for nonoperative management and to overcome possible renal trauma grade misclassification. [ABSTRACT FROM AUTHOR]

Purpose: We assessed venous thromboembolism (VTE) and associated risk factors following artificial urinary sphincter (AUS) and inflatable penile prosthesis (IPP) surgery. Materials and Methods: Using IBM® MarketScan, a commercial claims database, patients undergoing AUS and IPP surgery were identified using CPT® and ICD (International Classification of Diseases)-10 procedure codes between 2008 and 2017. ICD-9 and -10 codes were used to identify health care visits associated with lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE) within 90 days of surgery. Covariates were assessed using a multivariable model to determine association with outcome of DVT and/or PE. Results: A total of 21,413 men underwent AUS (4,870) or IPP (16,543) surgery between 2008 and 2017 with a median age of 62 years and 68 years, respectively. DVT and PE events following AUS and IPP surgery occurred in 1.54% and 1.04%, respectively. A history of varicose veins (HR 2.76; 95% CI 1.11e6.79), prior history of DVT (HR 13.65; 95% CI 7.4e25.19), or PE (HR 7.65; 95% CI 4.01e14.6) in those undergoing AUS surgery was highly associated with development of postoperative VTE. Likewise, prior history of DVT (HR 12.6; 95% CI 7.99e19.93) and PE (HR 8.9; 95% CI 5.6e14.13) was strongly associated with a VTE event following IPP surgery. Conclusions: In a large cohort of men undergoing AUS and IPP surgery, 1.54% and 1.04% of men experienced a VTE event within 90 days of surgery, respectively. Prior history of varicose veins, DVT, and PE was associated with an increased likelihood of developing a postoperative DVT or PE. [ABSTRACT FROM AUTHOR]

Purpose: Postoperative surveillance urethroscopy has been shown to be an effective tool to predict reoperation within 1 year after urethroplasty. We aimed to evaluate early surveillance urethroscopy findings and long-term outcomes among urethroplasty patients in order to define the value of surveillance urethroscopy to predict failure. Materials and Methods: We evaluated 304 patients with at least 4 years of followup after urethroplasty performed at 10 institutions across the United States and Canada. All patients were surveilled using a flexible 17Fr cystoscope and were categorized into 3 groups: 1) normal lumen, 2) large-caliber stricture ((17Fr) defined as the ability of the cystoscope to easily pass the narrowing and 3) small-caliber stricture (<17Fr) that the cystoscope could not be passed. Failure was stricture recurrence requiring a secondary intervention. Results: The median followup time was 64.4 months (range 55.3e80.6) and the time to initial surveillance urethroscopy was 3.7 months (range 3.1e4.8) following urethroplasty. Secondary interventions were performed in 29 of 194 (15%) with normal lumens, 11 of 60 (18.3%) with 17Fr strictures and 32 of 50 (64%) with <17Fr strictures (p <0.001). The 1-, 3- and 9-year cumulative probability of intervention was 0.01, 0.06 and 0.23 for normal, 0.05, 0.17 and 0.18 for (17Fr, and 0.32, 0.50 and 0.73 for <17Fr lumen groups, respectively. Patient-reported outcome measures performed poorly to differentiate the 3 groups. Conclusions: Early cystoscopic visualization of scar recurrence that narrows the lumen to <17Fr following urethroplasty is a significant long-term predictor for patients who will eventually undergo a secondary intervention.

Purpose: Patients with high-grade renal trauma (HGRT) undergoing nephrectomy may be at higher risk for mortality compared to those treated conservatively. However, no study has controlled for degree of hemorrhage as a measure of shock. We hypothesized that after controlling for blood transfusions and other factors, nephrectomy after HGRT would be associated with increased mortality and acute kidney injury (AKI). Materials and Methods: We identified adult patients with HGRT (American Association for the Surgery of Trauma grade IIIeV) in TQIP (2013e2017). Propensity scoring was used to adjust for the probability of nephrectomy. Conditional logistic regression was used to analyze the association between nephrectomy and mortality and AKI. We adjusted for patient characteristics, injury specifics, and physiological factors including blood transfusions. Results: There were 12,780 patients with HGRT, and 1,014 (7.9%) underwent nephrectomy. Mortality was 10.6% and 4.2% in the nephrectomy and nonnephrectomy groups, respectively (p <0.001). In nephrectomy patients, 8.6% experienced AKI vs 2.4% of nonnephrectomy patients (p <0.001). In the adjusted analysis, there was no association between nephrectomy and mortality (OR[0.367, 95% CI 0.09e1.497, p[0.162). There was also no association between nephrectomy and AKI. Increasing age, nonCaucasian race, increasing Injury Severity Score, decreasing Glasgow Coma Score and blood transfusions were associated with higher mortality. For AKI, independent predictors included increasing age, male sex, and blood transfusions. Conclusions: After adjusting for volume of blood transfused in the first 24 hours, nephrectomy after HGRT was not associated with increased mortality or AKI. As a clinical principle, trauma nephrectomy should be avoided when possible. [ABSTRACT FROM AUTHOR]

To validate if better upper extremity (UE) motor function predicts clean intermittent catheterization (CIC) adoption and adherence after spinal cord injury (SCI) using a validated instrument (as opposed to prior research using scales based on expert opinion). We examined data from the Neurogenic Bladder Research Group SCI registry, a multicenter, prospective, observational study assessing persons with neurogenic bladder following SCI. All participants who were unable to volitionally void and were >1 year post injury were included. Participants were dichotomized into those performing CIC vs those using other bladder management methods. In addition to demographic and clinical characteristics, UE motor function was examined using the SCI-Fine Motor Function Index using validated categorization levels: (1) no activities requiring hand function, (2) some activities involving gross hand movement, (3) some activities requiring dexterity or coordinated UE movement, or (4) most activities requiring dexterity and coordinated UE movement. Associations were examined using logistic regression. Multicenter study. Registry participants unable to volitionally void after SCI (N=1236). Not applicable. Upper extremity motor function association with CIC. A total of 1326 individuals met inclusion criteria (66% performing CIC, 60% male, and 82% white). On multivariate analysis, better UE motor function was associated with a statistically increased odds of performing CIC (odds ratio, 3.10 [Level 3] and odds ratio, 8.12 [Level 4] vs Levels 1 and 2 [ P <.001]). In persons with SCI who are unable to volitionally void, UE motor function is highly associated with CIC. These results validate prior findings and continue to suggest that following SCI, the degree of preserved UE motor function is associated with CIC more than any other factor. [ABSTRACT FROM AUTHOR]

Purpose Approximately 10% to 20% of patients will have a recurrence after urethroplasty. Initial management of these recurrences is often by urethral dilation or direct vision internal urethrotomy. In the current study we describe the outcomes of endoscopic management of stricture recurrence after bulbar urethroplasty. Materials and Methods We retrospectively reviewed bulbar urethroplasty data from 5 surgeons in the TURNS (Trauma and Urologic Reconstruction Network of Surgeons). Men who underwent urethral dilation or direct vision internal urethrotomy for urethroplasty recurrence were identified. Recurrence was defined as the inability to pass a 17Fr cystoscope through the area of reconstruction. The primary outcome was the success rate of recurrence management. Comparisons were made between urethral dilation and direct vision internal urethrotomy, and then between endoscopic management of recurrences after excision and primary anastomosis urethroplasty vs substitutional repairs using time to event statistics. Results In 53 men recurrence was initially managed endoscopically. Median time to urethral stricture recurrence after urethroplasty was 5 months. At a median followup of 5 months the overall success rate was 42%. Success after urethral dilation was significantly less than after direct vision internal urethrotomy (1 of 10 patients or 10% vs 21 of 43 or 49%, p <0.001) with a failure HR of 3.15 (p = 0.03). Direct vision internal urethrotomy was more effective after substitutional failure than after excision and primary anastomosis urethroplasty (53% vs 13%, p = 0.005). Conclusions Direct vision internal urethrotomy was more successful than urethral dilation in the management of stricture recurrence after bulbar urethroplasty. Direct vision internal urethrotomy was more successful in patients with recurrence after substitution urethroplasty compared to after excision and primary anastomosis urethroplasty. Perhaps this indicates a different mechanism of recurrence for excision and primary anastomosis urethroplasty (ischemic) vs substitution urethroplasty (nonischemic). [ABSTRACT FROM AUTHOR]

Purpose In this study we aimed to define the prevalence of preoperative and postoperative post-micturition incontinence or post-void dribbling after anterior urethroplasty for urethral stricture disease. We also sought to determine risk factors for its presence. Materials and Methods We retrospectively reviewed a prospectively maintained, multi-institutional urethral stricture database to evaluate post-micturition incontinence using a single question from a validated questionnaire, “How often have you had a slight wetting of your pants a few minutes after you had finished urinating and had dressed yourself?” Possible answers were never—0 to all the time—3. The presence of post-micturition incontinence was defined as any answer greater than 0. Comparisons were made to stricture type and location, repair type and patient medical comorbidities. Results Preoperative and postoperative post-micturition incontinence questionnaires were completed by 614 and 331 patients, respectively. Patients without complete data available were excluded from study. Preoperative post-micturition incontinence was present in 73% of patients, of whom 44% stated that this symptom was present most of the time. Overall postoperative post-micturition incontinence was present in 40% of patients and again it was not predicted by stricture location or urethroplasty type. Of the 331 patients with followup questionnaires 60% reported improvement, 32% reported no change and 8% reported worsening symptoms. The overall rate of de novo post-micturition incontinence was low at 6.3%. Conclusions The prevalence of preoperative post-micturition incontinence is high and likely under reported. In most patients post-micturition incontinence improves after urethroplasty and the prevalence of de novo post-micturition incontinence is low. The presence of post-micturition incontinence was not predicted by stricture length or location, or urethroplasty repair type. [ABSTRACT FROM AUTHOR]

Purpose To our knowledge anxiety and depression in patients with urethral stricture disease and the impact of urethroplasty on mental health has never been explored. We hypothesized that patients with urethral stricture disease would have higher than normal anxiety and depression levels, and urethroplasty would improve mental health. Materials and Methods We retrospectively reviewed the records of patients in a multi-institutional reconstructive urology database who underwent anterior urethroplasty. Preoperative and postoperative evaluation of anxiety and depression, and overall health was recorded using the validated EQ-5D™-3L Questionnaire. Sexual function was evaluated with the IIEF (International Index of Erectile Function) and the Men’s Sexual Health Questionnaire. Stricture recurrence was defined as the need for a subsequent procedure. Results Median followup in the 298 patients who met study inclusion criteria was 4.2 months. Preoperative anxiety and depression was reported by 86 patients (29%). Those with anxiety and depression reported higher rates of marijuana use, a worse preoperative IIEF score (17.5 vs 19.6, p = 0.01) and a lower image of overall health (66 vs 79, p ≤0.001). Improvement or resolution of anxiety and depression was experienced by 56% of patients treated with urethroplasty while de novo postoperative anxiety and depression were reported by 10%. These men reported a decreased flow rate (16 vs 25 ml per second, p = 0.01). Clinical failure in 8 patients (2.7%) had no effect on the development, improvement or resolution of anxiety and depression. Conclusions Of patients with preoperative anxiety and depression 56% reported improvement or resolution after urethroplasty. Although new onset anxiety and depression was rare, these patients had a significantly lower postoperative maximum flow rate, possibly representing a group with a perceived suboptimal surgical outcome. A urethral stricture disease specific questionnaire is needed to further elucidate the interplay of urethral stricture disease with anxiety and depression. [ABSTRACT FROM AUTHOR]

Purpose We evaluated the short and long-term surgical outcomes of urinary diversion done for urinary adverse events arising from prostate radiation therapy. We hypothesized that patient characteristics are associated with complications after urinary diversion. Materials and Methods We performed a retrospective cohort study of 100 men who underwent urinary diversion (urinary conduit or continent catheterizable pouch) due to urinary adverse events after prostate radiotherapy from 2007 to 2016 from 9 academic centers in the United States. Outcome measurements included predictors of short and long-term complications, and readmission after urinary diversion of patients who had prostate cancer treated with radiotherapy. The data were summarized using descriptive statistics and univariate associations with complications were identified with logistic regression controlling for center. Results Mean patient age was 71 years and median time from radiotherapy to urinary diversion was 8 years. Overall 81 (81%) patients had combined modality therapy (radical prostatectomy plus radiotherapy or various combinations of radiotherapy). Grade 3a or greater Clavien-Dindo complications occurred in 31 (35%) men, including 4 deaths (4.5%). Normal weight men had more short-term complications compared to overweight (OR 4.9, 95% CI 1.3–23.1, p=0.02) and obese men (OR 6.3, 95% CI 1.6–31.1, p=0.009). Hospital readmission within 6 weeks of surgery occurred for 35 (38%) men. Surgery was needed to treat long-term complications after urinary diversion in 19 (22%) patients with a median followup of 16.3 months. Conclusions Urinary diversion after prostate radiotherapy has a considerable short and long-term surgical complication rate. Urinary diversion most often cannot be avoided in these patients but appreciation of the risks allows for informed shared decision making between surgeons and patients. [ABSTRACT FROM AUTHOR]

Purpose Little published data exist on the impact of urethral stricture surgery on urinary urgency. We evaluated urinary urgency and urge incontinence before and after anterior urethroplasty. Materials and Methods Male patients who underwent 1-stage anterior urethroplasty were retrospectively identified at 8 centers. Patients with preoperative and 2-month or greater postoperative subjective urinary urgency assessments were included in study. Patients who received anticholinergic medications preoperatively were excluded. Univariate and multivariate analysis was done to analyze the association of patient characteristics with preoperative and postoperative symptoms as well as improvement or worsening of symptoms after surgery. Results Symptom and followup data on urgency and urge incontinence were available in in 439 and 305 patients, respectively. Preoperatively 58% of the men reported urgency and 31% reported urge incontinence. Postoperatively this decreased to 40% of men for urgency and 12% for urge incontinence (each p <0.01). Of the men 37% reported improvement in urgency and 74% experienced improvement in urge incontinence. Few of those without preoperative symptoms showed worse symptoms, including urgency in 9% and urge incontinence in 5%. New urgency was more likely to develop in men with a higher body mass index (OR 1.09, p = 0.02). Men with stricture recurrence were less likely to show improvement in urgency (OR 0.24, p = 0.03). Older men were more likely to have new urge incontinence (OR 1.06, p = 0.01) and less likely to notice improvement in urge symptoms (OR 0.92, p <0.01). Conclusions The prevalence of urgency and urge incontinence in male patients with anterior urethral stricture is high. The majority of men experience symptom stability or improvement in urinary urge symptoms following anterior urethroplasty. [ABSTRACT FROM AUTHOR]

Purpose Subjective measures of success after urethroplasty have become increasingly valuable in postoperative monitoring. We examined patient reported satisfaction following anterior urethroplasty using objective measures as a proxy for success. Materials and Methods Men 18 years old or older with urethral strictures undergoing urethroplasty were prospectively enrolled in a longitudinal, multi-institutional urethroplasty outcomes database. Preoperative and postoperative assessment included questionnaires to assess lower urinary tract symptoms, pain, satisfaction and sexual health. Analyses controlling for stricture recurrence (defined as the inability to traverse the reconstructed urethra with a flexible cystoscope) were performed to determine independent predictors of dissatisfaction. Results At a mean followup of 14 months we found a high 89.4% rate of overall postoperative satisfaction in 433 patients and a high 82.8% rate in those who would have chosen the operation again. Men with cystoscopic recurrence were more likely to report dissatisfaction (OR 4.96, 95% CI 2.07–11.90) and men reporting dissatisfaction had significantly worse uroflowmetry measures (each p <0.02). When controlling for recurrence, multivariate analysis revealed that urethra and bladder pain (OR 1.71, 95% CI 1.05–2.77 and OR 2.74, 95% CI 1.12–6.69, respectively), a postoperative decrease in sexual activity (OR 4.36, 95% CI 2.07–11.90) and persistent lower urinary tract symptoms (eg straining to urinate OR 3.23, 1.74-6.01) were independent predictors of dissatisfaction. Conclusions Overall satisfaction after anterior urethroplasty is high and traditional measures of surgical success strongly correlate with satisfaction. However, independently of the anatomical appearance of the reconstructed urethra, postoperative pain, sexual dysfunction and persistent lower urinary tract symptoms were predictors of patient dissatisfaction.

Purpose Lichen sclerosus is a chronic, inflammatory skin condition of the genitalia of unknown origin that accounts for nearly 10% of urethral stricture disease. In this study we determine systemic comorbidities associated with lichen sclerosus in men. Materials and Methods We analyzed data from 1,151 men who were enrolled in a multi-institutional prospective urethroplasty outcomes database. Individuals were grouped by stricture etiology, and baseline demographics, medical histories and patient reported outcome measures were retrospectively compared across groups. Results Of the 1,151 men in the database 81 (7.0%) were noted to have lichen sclerosus related urethral stricture disease. Average patient age was 46.06 ± 16.52 years, with those with lichen sclerosus being significantly older than those without lichen sclerosus (51.26 ± 13.84 vs 45.68 ± 16.64, p = 0.0011). Men with lichen sclerosus were more likely to have hypertension, hyperlipidemia and diabetes, and to use tobacco products. Controlling for age, men with lichen sclerosus related urethral stricture disease had a higher body mass index (aOR 1.089, 95% CI 1.050–1.130), and were more likely to have hypertension (aOR 2.028, 1.21–3.41) and be active tobacco users (aOR 2.0, 1.36–3.40). Mean preoperative patient reported outcome measures scores for urinary and sexual function were similar. Controlling for stricture length and location, the adjusted odds of surgical failure were higher for lichen sclerosus related urethral stricture disease (aOR 1.9, 95% CI 0.9–4.2). Conclusions Lichen sclerosus related urethral stricture disease is associated with chronic systemic diseases. This association may implicate a systemic inflammatory and/or autoimmune pathophysiology. A 2-hit mechanism implicating local and systemic factors for lichen sclerosus related urethral stricture disease development and progression is hypothesized. [ABSTRACT FROM AUTHOR]

Purpose Injection of mitomycin C may increase the success of transurethral incision of the bladder neck for the treatment of bladder neck contracture. We evaluated the efficacy of mitomycin C injection across multiple institutions. Materials and Methods Data on all patients who underwent transurethral incision of the bladder neck with mitomycin C from 2009 to 2014 were retrospectively reviewed from 6 centers in the TURNS. Patients with at least 3 months of cystoscopic followup were included in the analysis. Results A total of 66 patients underwent transurethral incision of the bladder neck with mitomycin C and 55 meeting the study inclusion criteria were analyzed. Mean ± SD patient age was 64 ± 7.6 years. Dilation or prior transurethral incision of the bladder neck failed in 80% (44 of 55) of patients. Overall 58% (32 of 55) of patients achieved resolution of bladder neck contracture after 1 transurethral incision of the bladder neck with mitomycin C at a median followup of 9.2 months (IQR 11.7). There were 23 patients who had recurrence at a median of 3.7 months (IQR 4.2), 15 who underwent repeat transurethral incision of the bladder neck with mitomycin C and 9 of 15 (60%) who were free of another recurrence at a median of 8.6 months (IQR 8.8), for an overall success rate of 75% (41 of 55). Incision with electrocautery (Collins knife) was predictive of success compared with cold knife incision (63% vs 50%, p=0.03). Four patients experienced serious adverse events related to mitomycin C and 3 needed or are planning cystectomy. Conclusions The efficacy of intralesional injection of mitomycin C at transurethral incision of the bladder neck was lower than previously reported and was associated with a 7% rate of serious adverse events.

Purpose Anterior urethral stricture disease most commonly presents as urinary obstruction. Lower urinary tract pain is not commonly reported as a presenting symptom. We prospectively characterized lower urinary tract pain in association with urethral stricture disease and assessed the effects of urethroplasty on this pain. Materials and Methods Men (18 years old or older) with anterior urethral stricture disease were prospectively enrolled in a longitudinal, multi-institutional, urethral reconstruction outcomes study from June 2010 to January 2013 as part of TURNS (Trauma and Urologic Reconstruction Network of Surgeons). Preoperative and postoperative lower urinary tract pain was assessed by the validated CLSS. Voiding and sexual function was assessed using validated patient-reported measures, including I-PSS. Results Preoperatively 118 of 167 men (71%) reported urethral pain and 68 (41%) reported bladder pain. Age was the only predictor of urethral pain with men 40 years or younger reporting more pain than those 60 years old or older (81% vs 58%, p = 0.0104). Lower urinary tract pain was associated with worse quality of life and overall voiding symptoms on CLSS and I-PSS (each p <0.01). Postoperatively lower urinary tract pain completely resolved in 64% of men with urethral pain and in 73.5% with bladder pain. There were no predictive factors for changes in lower urinary tract pain after urethral reconstruction. Conclusions Lower urinary tract pain is common in urethral stricture disease, especially in younger men. It is associated with worse quality of life and voiding function. In most men lower urinary tract pain resolves after urethral reconstruction. [ABSTRACT FROM AUTHOR]

Purpose We compared the outcomes of various adult continent catheterizable channels in a multi-institutional setting. Materials and Methods We retrospectively reviewed the records of all adults who underwent construction of a continent catheterizable channel at our 4 institutions from 2004 to 2013 and who had at least 6 months of followup. Patients were stratified by channel type, including continent cutaneous ileal cecocystoplasty or tunneled cutaneous channel, eg appendicovesicostomy, Monti channel, etc. The primary study outcome was the need for a secondary procedure to correct stomal leakage, catheterizable channel obstruction or stomal stenosis. Secondary outcomes were patient reported leakage and 30-day postoperative complications. We used Firth logistic regression to control for the heterogeneity induced by multiple institutions. Results A total of 61 patients were included in study, of whom 31 underwent continent cutaneous ileal cecocystoplasty. Mean age was 41.4 years (range 22 to 76). Median followup was 16 months. More patients with a tunneled channel required a secondary procedure than those with cecocystoplasty (15 of 30 or 50% vs 4 of 31 or 13%, OR 6.4, 95% CI 1.8-28). The total number of required secondary procedures was also greater for tunneled channels than for cecocystoplasty (27 vs 4). Of patients with cecocystoplasty 29% reported stomal leakage compared with 43% of those with a tunneled channel (p = 0.12). A high rate of postoperative complications was observed regardless of technique, including 40% for channels and 51.7% for cecocystoplasty. Conclusions Patients with continent cutaneous ileal cecocystoplasty undergo fewer interventions to maintain the catheterizable channel than patients with a tunneled continent catheterizable channel.

Purpose: Prostate cancer treatment results in several sexually related side effects beyond the well studied erectile dysfunction. Climacturia (leakage of urine during orgasm) has been reported after prostatectomy but studies have been limited by multiple factors. In this study we examine the prevalence, causes and impact on orgasm function of climacturia after definitive treatment of prostate cancer with surgery or radiation. Materials and Methods: A total of 906 anonymous surveys were sent to patients with prostate cancer treated with surgery and/or radiation. Respondents were asked about the presence of urinary leakage, climacturia and various elements related to sexual and orgasmic function. We estimated the prevalence of climacturia, evaluated the differences between those with and without climacturia, and assessed the impact of climacturia on orgasmic function. Results: Overall 412 surveys were returned and available for analysis, and of these respondents 75.2% were sexually active or experiencing orgasms. Climacturia was reported by 22.6% of these respondents, and by 28.3%, 5.2% and 28.6% of those treated with surgery, radiation, or both, respectively (p <0.001). The use of aides to obtain an erection (OR 2.24, 95% CI 1.08–4.93, p = 0.035) and the presence of urinary incontinence (OR 3.09, 95% CI 1.66–5.88, p <0.001) were also associated with climacturia in a multivariate logistic regression model. Climacturia had no significant impact on orgasmic function and satisfaction. Conclusions: Climacturia is experienced by a substantial proportion of men after undergoing definitive treatment of prostate cancer. We found a complex relationship between stress urinary incontinence and climacturia, and noted that the presence of climacturia does not necessarily negatively impact sexual satisfaction.

Purpose: Investigators from Parkland Hospital proposed substratification of the AAST (American Association for the Surgery of Trauma) grading scale based on 3 risk factors, including active vascular extravasation, a medial laceration and a perinephric hematoma of greater than 3.5 cm. We hypothesized that these characteristics would also be associated with intervention for renal hemorrhage in our large trauma series. Materials and Methods: From January 2005 to January 2011 we retrospectively reviewed the renal trauma records at adult level 1 trauma centers in Utah. AAST grade 3 and 4 injuries were characterized based on the mentioned 3 risk factors. Our primary outcome was intervention to control renal hemorrhage. Results: AAST grade 3 or greater injury was identified in 147 patients, including 115 who had grade 3 and 4 injuries as well as imaging available for review. There were 63 grade 3 (53%) and 52 grade 4 (43%) renal injuries. Eight patients (7%) underwent intervention for renal hemorrhage. Vascular extravasation (OR 16.4, 95% CI 2.6–179.8, p <0.001) and perinephric hematoma greater than 3.5 cm (OR 8.4, 95% CI 1.4–52.5, p = 0.0099) were associated with intervention, while a medial laceration was not (p = 0.454). Patients with 1 or fewer, 2 and 3 risk factors had an intervention rate of less than 2.9%, 18% and 50%, respectively (p <0.001). Conclusions: Vascular extravasation, a perinephric hematoma greater than 3.5 cm and the number of risk factors (0 to 3) were associated with intervention for renal hemorrhage. Our findings are similar to those at Parkland Hospital. These imaging features may serve as useful prognostic indicators for renal trauma. [ABSTRACT FROM AUTHOR]

Purpose: Male urethral stricture disease accounts for a significant number of hospital admissions and health care expenditures. Although much research has been completed on treatment for urethral strictures, fewer studies have addressed the treatment of strictures in men with recurrent stricture disease after failed prior urethroplasty. We examined outcome results for repeat urethroplasty. Materials and Methods: A prospectively collected, single surgeon urethroplasty database was queried from 1977 to 2011 for patients treated with repeat urethroplasty after failed prior urethral reconstruction. Stricture length and location, and repeat urethroplasty intervention and failure were evaluated with descriptive statistics, and univariate and multivariate logistic regression. Results: Of 1,156 cases 168 patients underwent repeat urethroplasty after at least 1 failed prior urethroplasty. Of these patients 130 had a followup of 6 months or more and were included in analysis. Median patient age was 44 years (range 11 to 75). Median followup was 55 months (range 6 months to 20.75 years). Overall, 102 of 130 patients (78%) were successfully treated. For patients with failure median time to failure was 17 months (range 7 months to 16.8 years). Two or more failed prior urethroplasties and comorbidities associated with urethral stricture disease were associated with an increased risk of repeat urethroplasty failure. Conclusions: Repeat urethroplasty is a successful treatment option. Patients in whom treatment failed had longer strictures and more complex repairs. [Copyright &y& Elsevier]

Purpose: Adults with complications from previous hypospadias surgery experience various problems, including urethral stricture, persistent hypospadias and urethrocutaneous fistula. Innate deficiencies of the corpus spongiosum and multiple failed operations makes further management challenging. Materials and Methods: We reviewed our prospective urethroplasty database of men who presented with complications of previous hypospadias surgery. Patients were included in study if they had greater than 6 months of followup. Our surgical management was defined as an initial success if there were no urethral complications. The overall success rate included men with the same result after additional treatment. Results: A total of 50 men had followup greater than 6 months (median 89) and were included in study. These 50 patients presented with urethral stricture (36), urethrocutaneous fistula (12), persistent hypospadias (7), hair in the urethra (6) and severe penile chordee (7). Patients underwent a total of 74 urethroplasties, including stage 1 urethroplasty in 19, a penile skin flap in 11, stage 2 urethroplasty in 11, urethrocutaneous fistula closure in 9, permanent perineal urethrostomy in 6, excision and primary anastomosis in 6, a 1-stage buccal mucosa onlay in 4, tubularized plate urethroplasty in 3, combined techniques in 3 and chordee correction in 1. In 25 men (50%) treatment was initially successfully. Of the 25 men in whom surgery failed 18 underwent additional procedures, including 13 who were ultimately treated successfully for an overall 76% success rate (38 of 50). Conclusions: Managing problems from previous hypospadias surgery is difficult with a high initial failure rate. Additional procedures are commonly needed. [Copyright &y& Elsevier]

Purpose: We studied the patient risk factors that promote urethroplasty failure. Materials and Methods: Records of patients who underwent urethroplasty at the University of California, San Francisco Medical Center between 1995 and 2004 were reviewed. Cox proportional hazards regression analysis was used to identify multivariate predictors of urethroplasty outcome. Results: Between 1995 and 2004, 443 patients of 495 who underwent urethroplasty had complete comorbidity data and were included in analysis. Median patient age was 41 years (range 18 to 90). Median followup was 5.8 years (range 1 month to 10 years). Stricture recurred in 93 patients (21%). Primary estimated stricture-free survival at 1, 3 and 5 years was 88%, 82% and 79%. After multivariate analysis smoking (HR 1.8, 95% CI 1.0–3.1, p = 0.05), prior direct vision internal urethrotomy (HR 1.7, 95% CI 1.0–3.0, p = 0.04) and prior urethroplasty (HR 1.8, 95% CI 1.1–3.1, p = 0.03) were predictive of treatment failure. On multivariate analysis diabetes mellitus showed a trend toward prediction of urethroplasty failure (HR 2.0, 95% CI 0.8–4.9, p = 0.14). Conclusions: Length of urethral stricture (greater than 4 cm), prior urethroplasty and failed endoscopic therapy are predictive of failure after urethroplasty. Smoking and diabetes mellitus also may predict failure potentially secondary to microvascular damage. [Copyright &y& Elsevier]

Purpose: We evaluated the effect of partial bladder outlet obstruction on bladder weight, protein synthesis, mitotic markers and the mitogen activated protein kinase pathway in a mouse model. Materials and Methods: Mice were divided into 3 groups, including control, sham treated and partially obstructed. Bladders were harvested from the mice in the partially obstructed group 12, 24, 48, 72 and 168 hours after surgical partial outlet obstruction, respectively. Partially obstructed bladders were compared to bladders in the control and sham treated groups by weight, protein content, and expression of proliferating cellular nuclear antigen, cyclin D3, HsP 70, c-jun and phosphorylated c-jun. Bladders were examined histologically for changes occurring with partial obstruction. Results: We tested 3 groups of mice, including control, sham treated and partially obstructed mice, to understand the pathophysiology of the bladder response to partial obstruction. We found no statistical difference in body weight among the groups. Furthermore, there was a significant increase in bladder weight and protein content in partially obstructed mice compared to those in controls and sham operated mice. There was up-regulation of proliferating cellular nuclear antigen, cyclin D3, HsP70, c-jun and phosphorylated c-jun with partial obstruction. Fibrosis was prominent at 168 hours compared to that in controls. Conclusions: Bladder weight and protein content increase with partial bladder outlet obstruction in mice. Cell cycle proteins and elements of the mitogen activated protein kinase pathway are up-regulated during this process. [Copyright &y& Elsevier]

Abstract: Purpose: The teratoid histologic variant of Wilms’ tumor is rare, with only 15 prior reported cases. We review these and report an additional case in which a cytogenetic abnormality was identified that has not previously been reported in a teratoid Wilms’ tumor. Materials and methods: A medline search revealed 15 previously reported cases of the teratoid variant of Wilms’ tumor. We summarized the characteristics of these cases with attention to radiologic appearance, stage, laterality, histology, response to chemotherapy and outcomes. Results: Characteristic radiologic features suggesting teratoid Wilms’ tumor were calcific densities and stippling, or areas of attenuation indicating adipose tissue. The majority of teratoid Wilms’ tumor patients had a high tumor stage at presentation (50% stage III or greater). The incidence of bilateral tumors was 38%. Chemotherapy was administered in nine cases and in only one (11%) was there a cytoreductive response. Four deaths (25%) occurred amongst these patients. Conclusions: Teratoid Wilms’ tumors appear to present with a high stage, increased incidence of bilaterality and have a high mortality rate. Treatment strategies should focus on total surgical extirpation, including metastatic sites when feasible, due to this entity''s limited response to chemotherapy. [Copyright &y& Elsevier]

Introduction It is generally accepted that there is a risk of hypertension after renal trauma, particularly in high-grade and devascularizing injuries. Hypertension following renal trauma is estimated to occur in five percent of adults, however, the incidence is unknown in the pediatric population. Materials and methods We performed a retrospective review of all pediatric trauma patients at Primary Children’s Hospital in Salt Lake City, Utah between 2002 and 2012. We included all children age ≤ 17 years old with American Association for Surgery of Trauma (AAST) grade 3–5 renal injury. Hypertension was defined as persistent hypertension that required anti-hypertensive medications. Our primary outcomes were incidence of hypertension during the acute trauma and in long-term follow. Results A total of 62 children were identified with AAST grade 3–5 renal injuries during our study period. Follow up blood pressures were recorded in 36 (58%) of these children with a median follow of 4.1 years (IQR 2.1–5.1 years) after trauma. Four children (6.5%) were identified to have some degree of hypertension while hospitalized after trauma and started on anti-hypertensive medication. Two out of these four children remained on hypertensive medication at follow up, while the remaining two children’s hypertension resolved. No children who were normotensive in the immediate post-trauma period, developed delayed hypertension during long-term follow up. Conclusions There is a low risk of developing hypertension following severe renal trauma in the pediatric population. Patients who develop long-term problems with hypertension after renal trauma manifest it during the initial hospitalization, rather than subsequently during the long-term. [ABSTRACT FROM AUTHOR]
