Erosion rates of 3.5-cm artificial urinary sphincter cuffs are similar to larger cuffs.

OBJECTIVE: To compare long-term outcomes and erosion rates of 3.5-cm artificial urinary sphincter (AUS) cuffs vs larger cuffs amongst men with stress urinary incontinence (SUI), with and without a history of pelvic radiotherapy (RT). PATIENTS AND METHODS: We reviewed the records of all men who underwent AUS placement by a single surgeon between September 2009 and June 2017 at our tertiary urban medical centre. A uniform perineal approach was used to ensure cuff placement around the most proximal corpus spongiosum after precise spongiosal measurement. Patients were stratified by cuff size and RT status, and patient demographics and surgical outcomes were analysed. Cases of AUS revision in which a new cuff was not placed were excluded. Success was defined as patient-reported pad use of ≤1 pad/day. RESULTS: Amongst 410 cases included in the analysis, the 3.5-cm cuff was used in 166 (40.5%), whilst 244 (59.5%) received larger cuffs (≥4.0 cm). Over a median follow-up of 50 months, there was AUS cuff erosion in 44 patients at a rate nearly identical in the 3.5-cm cuff (10.8%, 18/166) and the ≥4-cm cuff groups (10.7%, 26/244, P = 0.7). On multivariate logistic regression, clinical factors associated with AUS cuff erosion included a history of pelvic RT, prior AUS cuff erosion, prior urethroplasty, and a history of inflatable penile prosthesis (IPP) placement. Patient demographics were similar between the cuff-size groups; including age, body mass index, comorbidities, smoking history, RT history, prior AUS, and prior IPP placement. Continence rates were high amongst all AUS patients, with similar success in both groups (82% for 3.5-cm cuff, 90% for ≥4-cm cuff, P = 0.1). CONCLUSIONS: After 8 years of experience and extended follow-up, the outcomes of the 3.5-cm AUS cuff appear to be similar to ≥4-cm cuffs for effectiveness and rates of urethral erosion. RT patients have a higher risk of cuff erosion regardless of cuff size.

Delayed Reconstruction of Bulbar Urethral Strictures is Associated with Multiple Interventions, Longer Strictures and More Complex Repairs.

PURPOSE: Prior to urethral reconstruction many patients with stricture undergo a variable period during which endoscopic treatments are performed for recurrent obstructive symptoms. We evaluated the association among urethroplasty delay, endoscopic treatments and subsequent reconstructive outcomes. MATERIALS AND METHODS: We reviewed the records of men who underwent primary bulbar urethroplasty from 2007 to 2014. Those with prior urethroplasty, penile and/or membranous strictures and incomplete data were excluded from analysis. Men were stratified by a urethroplasty delay of less than 5, 5 to 10 or greater than 10 years from diagnosis. RESULTS: A total of 278 primary bulbar urethroplasty cases with complete data were evaluated. Median time between stricture diagnosis and reconstruction was 5 years (IQR 2-10). Patients underwent an average ± SD of 0.9 ± 2.4 endoscopic procedures per year of delay. Relative to less than 5 and 5 to 10 years a delay of greater than 10 years was associated with more endoscopic treatments (median 1 vs 2 vs 5), repeat self-dilations (13% vs 14% vs 34%), strictures longer than 2 cm (40% vs 39% vs 56%) and complex reconstructive techniques (17% vs 17% vs 34%). An increasing number of endoscopic treatments was independently associated with strictures longer than 2 cm (OR 1.06, p = 0.003), which had worse 24-month stricture-free survival than shorter strictures (83% vs 96%, p = 0.0003). Each consecutive direct vision internal urethrotomy was independently associated with the risk of urethroplasty failure (HR 1.19, p = 0.02). CONCLUSIONS: Urethroplasty delay is common and often associated with symptomatic events managed by repeat urethral manipulations. Endoscopic treatments appear to lengthen strictures and increase the complexity of repair.

Penoscrotal Decompression-Promising New Treatment Paradigm for Refractory Ischemic Priapism.

BACKGROUND: For prolonged ischemic priapism, outcomes after distal shunt are poor, with only 30% success for priapic episodes lasting longer than 48 hours. AIM: To present a novel, glans-sparing approach of corporal decompression through a penoscrotal approach for cases of refractory ischemic priapism (RIP) after failed distal shunt procedures. METHODS: We describe the technique and present our initial experience with penoscrotal decompression (PSD) for treatment of RIP after failed distal shunt. We compared outcomes of patients with RIP undergoing surgical management using PSD or malleable penile prosthesis (MPP) placement after failed distal penile shunt procedures (2008-2017). OUTCOMES: Our initial experience showed favorable outcomes with PSD compared with early MPP placement in patients with RIP whose distal shunt failed. RESULTS: Of 14 patients with RIP undergoing surgical management after failed distal penile shunt procedures, all patients presented after a prolonged duration of priapism (median = 61 hours) after which the priapism was refractory to multiple prior treatments (median = 3, range = 1-75) including at least 1 distal shunt. MPP was inserted in 8 patients (57.1%), whereas the most recent 6 patients (42.9%) underwent PSD. All patients with PSD (6 of 6, 100%) were successfully treated with corporal decompression without additional intervention and noted immediate relief of pain postoperatively. In contrast, 37.5% of patients (3 of 8) undergoing MPP after failed distal shunt procedures required a total of 8 revision surgeries during a median follow-up of 41.5 months. The most common indications for revision surgery after MPP placement included distal (4 of 8, 50%) and impending lateral (2 of 8, 25%) extrusion. CLINICAL IMPLICATIONS: PSD is a simple, effective technique in the management of RIP after failed distal shunt procedures with fewer complications than MPP placement. STRENGTHS AND LIMITATIONS: Although PSD is effective in the management of RIP after failed distal shunt procedures, long-term assessment of erectile function and ease of future penile prosthetic implantation is needed. CONCLUSION: Corporal decompression resolves RIP through a glans-sparing approach and avoids the high complication rate of prosthetic insertion after failed distal shunt procedures.

Refined nomogram incorporating standing cough test improves prediction of male transobturator sling success.

AIMS: To develop a decision aid in predicting sling success, incorporating the Male Stress Incontinence Grading Scale (MSIGS) into existing treatment algorithms. METHODS: We reviewed men undergoing first-time transobturator sling for stress urinary incontinence (SUI) from 2007 to 2016 at our institution. Patient demographics, reported pads per day (PPD), and Standing Cough Test (SCT) results graded 0-4, according to MSIGS, were assessed. Treatment failure was defined as subsequent need for >1 PPD or further procedures. Parameters associated with failure were included in multivariable logistic models, compared by area under the receiver-operating characteristic curves. A nomogram was generated from the model with greatest AUC and internally validated. RESULTS: Overall 203 men (median age 67 years, IQR 63-72) were evaluated with median follow-up of 45 months (IQR 11-75 months). A total of 185 men (91%) were status-post radical prostatectomy and 29 (14%) had pelvic radiation history. Median PPD and SCT grade were both two. Eighty men (39%) failed treatment (use of ≥1 PPD or subsequent anti-incontinence procedures) at a median of 9 months. History of radiation (P = 0.03), increasing MSIGS (P < 0.0001) and increasing preoperative PPD (P < 0.0001) were associated with failure on univariate analysis. In a multivariable model with AUC 0.81, MSIGS, and PPD remained associated (P = 0.002 and <0.0001 respectively, and radiation history P = 0.06), and was superior to models incorporating PPD and radiation alone (AUC 0.77, P = 0.02), PPD alone (AUC 0.76, P = 0.02), and a cutpoint of >2 PPD alone (AUC 0.71, P = 0.0001). CONCLUSIONS: MSIGS adds prognostic value to PPD in assessing success of transobturator sling for treatment of SUI.

Synchronous Ipsilateral High Submuscular Placement of Prosthetic Balloons and Reservoirs.

INTRODUCTION: Synchronous ipsilateral high submuscular placement of artificial urinary sphincter (AUS) pressure-regulating balloons (PRBs) and inflatable penile prosthesis (IPP) reservoirs in a single submuscular tunnel is a novel strategy that could be advantageous for patients who have had major pelvic surgery. AIM: To report our initial experience with synchronous ipsilateral vs bilateral placement of AUS PRBs and IPP reservoirs in men undergoing implant surgery. METHODS: We retrospectively reviewed all patients undergoing synchronous AUS and IPP placement from 2007 through 2015 by a single surgeon at our tertiary center. Patients were stratified according to ipsilateral vs bilateral placement of the AUS PRB and IPP reservoir. MAIN OUTCOME MEASURES: Reoperation rates because of infectious or erosive complications and mechanical failure were assessed. RESULTS: Of the 968 implant surgeries during the study period, 47 men had synchronous device placement, of whom 17 (36%) underwent ipsilateral placement of the PRB and reservoir. During a median follow-up of 19 months (range = 1-84 months), reoperations were necessary in 12 of 47 (26%) and were similar between groups (ipsilateral, 5 of 17, 29%; bilateral, 7 of 30, 23%; P = .73). Most reoperations were due to AUS-related complications (10 of 12, 83%) and nearly all patients with reoperation (10 of 12, 83%) had compromised urethras (ie, prior urethral surgery, radiation, or prior AUS implantation). The most common indication for reintervention was cuff erosion (4 of 47, 9%), with no difference between groups (ipsilateral, 3 of 17, 18%; bilateral, 1 of 30, 3%; P = .13). CONCLUSION: Synchronous ipsilateral high submuscular placement of urologic prosthetic balloons could safely facilitate prosthetic surgery in patients with a history of major pelvic and inguinal surgery.

Preoperative Urine Culture Results Correlate Poorly With Bacteriology of Urologic Prosthetic Device Infections.

INTRODUCTION: Although preoperative negative urine culture results and treatment of urinary tract infections are generally advised before artificial urinary sphincter (AUS) and penile prosthesis (PP) surgery to prevent device infection, limited evidence exists to support this practice. AIM: To evaluate the relation between preoperative urine culture results and the bacteriology of prosthetic device infections. METHODS: Men undergoing AUS and/or PP placement at a tertiary referral center from 2007 through 2015 were analyzed. A total of 713 devices were implanted in 681 patients (337 AUSs in 314 patients and 376 PPs in 367 patients), of whom 259 (36%) did not have preoperative urine culture and were excluded. The remaining 454 patients received standard broad-spectrum perioperative antibiotics. Two patient groups were identified based on preoperative urine cultures: group 1 had negative urine culture results and group 2 had untreated asymptomatic positive urine culture results identified postoperatively. MAIN OUTCOME MEASURES: Device infection was diagnosed clinically and cultures obtained from the explanted device and tissue spaces were compared with preoperative urine culture results. RESULTS: Although multivariate analysis showed that patients undergoing AUS placement had a 4.5-fold greater risk of positive urine culture results (114 of 250, 45%) compared with those undergoing PP placement (36 of 204, 18%; P < .001), infection rates between device types were similar (8 of 250 for AUSs [3%] and 7 of 204 for PPs [3%]; P = .89). At a median follow-up of 15 months, device infection occurred in 15 of 454 devices (3%) implanted and no differences in infection rates were noted between urine culture groups (10 of 337 in group 1 [3.3%] and 5 of 117 in group 2 [4.3%]; P = .28). Remarkably, only 1 of 15 device infections (7%) had the same organism present at preoperative urine culture. CONCLUSIONS: Despite the finding that patients with AUS placement had a 4.5 times higher rate of positive urine culture results than patients with PP placement, preoperative urine culture results appeared to show little correlation with the bacteriology of prosthetic device infections.

Inflatable penile prosthesis as tissue expander: what is the evidence?

OBJECTIVE: Many patients who undergo inflatable penile prosthesis (IPP) replacement are often upsized to larger cylinders, suggesting the IPP may serve as a tissue expander and increase internal penile length. The objective of this study is to evaluate whether cylinder length increases with subsequent IPP insertion. MATERIALS AND METHODS: We queried American Medical Systems and Coloplast Patient Information Form databases to identify patients who underwent IPP placement and replacement between 2004-2013. Patients were grouped by device type and time to replacement (<2 or ≥2 years). We selected the 2-year mark for subgroup analysis to allow time for tissue expansion to occur and to exclude patients who underwent early explantation (e.g. erosion or infection). RESULTS: Two thousand, seven hundred and forty nine patients (1,532 AMS 700 LGX, 717 AMS 700 CX, and 500 Coloplast Titan) met the inclusion criteria. Mean time between implants was earlier for LGX (29 months) than CX (39 months) and Titan (48 months) patients (p<0.001). Patients who underwent device replacement at <2 years did not experience an increase in mean cylinder length. On the contrary, patients who underwent device replacement at ≥2 years did experience significant increases in mean cylinder length (LGX 1.2 cm, CX 1.1 cm, and Titan 0.9 cm, p<0.001). The mean increases in length at ≥2 years were similar between the 3 devices (p=0.20). Sixty percent of patients demonstrated increases of >0.5 cm and 40% demonstrated increases of ≥1 cm. CONCLUSIONS: As demonstrated, the IPP may provide tissue expansion over time. Further evaluation is needed to determine if increased cylinder length correlates to increased functional length and patient satisfaction.

Outpatient buccal mucosal graft urethroplasty outcomes are comparable to inpatient procedures.

BACKGROUND: We sought to compare outcomes between inpatient and outpatient buccal mucosal graft (BMG) urethroplasty among a large tertiary referral center series. METHODS: A retrospective review of consecutive patients who underwent BMG urethroplasty between 2007 and 2018 was performed, including only first stage and one stage graft procedures. Patients were divided into inpatient and outpatient groups. Demographic and outcome data were collected and analyzed, with success defined as no need for further endoscopic or open reoperative management. RESULTS: Of 143 patients undergoing BMG urethroplasty during the study period, 87 cases (60.8%) were performed on an inpatient basis, and 56 (39.2%) on an outpatient basis. Patient characteristics such as age, BMI, prior endoscopic procedures and co-morbid factors were similar between inpatient and outpatient groups. Perioperative characteristics such as estimated blood loss were also similar between groups, but the inpatient cohort had a longer operative time (157.6 vs. 123.1 min, P<0.0001). Operative success was comparable in the two groups (74.7% inpatient vs. 76.8% outpatient, P=0.7) as were rates of complications (29.9% inpatient vs. 26.8% outpatient, P=0.07). CONCLUSIONS: BMG urethroplasty can be safely performed in an ambulatory setting without increased complications or compromised outcomes.

Changing Trends in Reconstruction of Complex Anterior Urethral Strictures: From Skin Flap to Perineal Urethrostomy.

OBJECTIVE: To evaluate procedural trends and outcomes for reconstruction of complex strictures at our tertiary center over the last decade. METHODS: We retrospectively reviewed complex urethral reconstruction comparing 3 techniques: (1) buccal mucosal graft (BMG), (2) penile skin flap, or (3) perineal urethrostomy (PU) at our center (2007-2017) with ≥6 months follow-up. Strictures amenable to anastomotic repair were excluded. Success was defined as no need for further operative management. RESULTS: Among 1129 strictures cases, 403 complex strictures were identified for analysis (median length 4.5 cm). Median age was 53.2 years (standard deviation ± 14.9). Reconstruction was most commonly performed using BMG (61.3%), followed by penile skin flap (21.6%) and PU (19.1%). PU use has increased steadily over the past decade, rising from 4.3% of case volume in 2008 to 38.7% in 2017 (P = .01). Over time, the proportion of reconstruction using BMG has remained stable, while penile skin flaps are now less commonly utilized. Over a median follow-up of 50.7 months, 16.9% (68/403) patients failed at a median of 13.9 months. Success rates were higher following PU (94.8%) compared to BMG and skin flaps (78.5% and 78.2%, respectively) (P = .003) despite PU patients being older (median age 62.6 years), having longer strictures (median 5.0 cm) and more commonly having lichen sclerosus (LS) (22.1%). CONCLUSION: Over a decade of a urethral reconstructive practice, PU has increasingly become preferred for older patients with long strictures and adverse etiology. BMG urethroplasty rates remain stable, while penile skin flap use is decreasing. Success rates of PU for these complex strictures are markedly higher than those of grafts and flaps.

Is Removal of the Pressure-regulating Balloon Necessary After Artificial Urinary Sphincter Cuff Erosion?

OBJECTIVE: To characterize the risk of delayed infectious complications from retained pressure-regulating balloons (PRBs) after artificial urinary sphincter (AUS) cuff erosion. METHODS: From our database of 530 AUS cases between 2007 and 2016, we identified 40 total AUS cuff erosions. Twenty-four (60%) presented without evidence of gross device infection and underwent explant of cuff and pump without removal of the PRB. Space of Retzius (SoR) and high submuscular (HSM) balloon locations were analyzed to assess for ease of removal. Presenting clinical features and retained balloon-related outcomes are reported. RESULTS: Of the 24 AUS cuff erosions with retained balloons, 6 (25%) men subsequently required PRB removal for infection during the median follow-up of 36 months (interquartile range 29-53). The median time to balloon infection after AUS erosion surgery was 4 months (interquartile range 4-16). Infection risk was reduced in those without concurrent inflatable penile prosthesis (20%) and in those who underwent "drain and retain" of the PRB (13%). The most common presenting clinical symptoms with retained PRB infection were pain and erythema near the site of the PRB (83%). No patient developed sepsis-related complications. The location of the PRB in this subcohort included 2 SoR and 4 HSM placements. The median operative time for balloon removal in the SoR was 3.5 times greater than that for HSM PRBs (133 minutes vs 38 minutes). CONCLUSION: With extended follow-up, three-quarters of the men with retained PRBs after AUS cuff erosion experienced no infectious complications. Removal of infected SoR PRBs was associated with greater operative times and surgical complexity relative to HSM PRBs.

Modified Transanosphincteric (York Mason) Repair of Nonradiated Rectourinary Fistulae: Patient-reported Fecal Continence Outcomes.

OBJECTIVE: To review our experience with the modified York Mason (MYM) procedure in the treatment of rectourinary fistulas (RUFs) and to assess fecal continence using patient-reported measures. MATERIALS AND METHODS: A retrospective review was performed of patients who underwent MYM repair of nonradiated RUF with gluteal free fat graft from 2008 to 2016 at a single institution. Success was defined as resolution of the fistula without need for further surgery. The Cleveland Clinic-Florida Wexner Fecal Incontinence Score (CCFFIS) and the Patient Global Impression of Improvement (PGI-I) surveys were administered by phone. RESULTS: Of 17 patients who underwent MYM repair with a mean age of 61.8 years old, the most common fistula etiologies were prostatectomy in 11 patients (65%), cryoablation in 2 patients (12%), and transanal tumor excision (12%). Three patients (18%) failed prior perineal repairs. The mean fistula size was 10.1 mm (range 2-25), the median operative time was 231 minutes (range 151-365), and the median length of stay was 2.0 days (range 1-13). At the median follow-up of 39.4 months, 16 of the 17 patients (94%) had successful primary closures. The condition of the 10 patients who responded to the phone survey was "much better" (median PGI-I score 2), with 89.5% mean improvement. The mean CCFFIS was 1.4 (range 0-5) on a scale of 0 (total continence) to 20 (complete incontinence). Two patients (20%) reported rare (<1 per month) fecal incontinence, and 2/10 (20%) reported frequent flatal incontinence, but none reported significant lifestyle change or sought further treatment for bowel symptoms. CONCLUSION: The MYM technique has a high success rate in the treatment of nonradiated RUF with negligible impact on fecal continence.

Prolonged Duration of Incontinence for Men Before Initial Anti-incontinence Surgery: An Opportunity for Improvement.

OBJECTIVE: To evaluate the duration and severity of male incontinence symptoms before presentation for initial anti-incontinence surgery (AIS) in a large tertiary subspecialty practice. Although male stress urinary incontinence (SUI) is known to profoundly compromise quality of life, many men do not undergo AIS in a timely manner. MATERIALS AND METHODS: We retrospectively reviewed our male patients with SUI (2007-2017) and assessed time from SUI onset to initial AIS across various demographics comparing male sling and artificial urinary sphincter (AUS). Reoperative cases were excluded. RESULTS: Among 786 cases, 572 men undergoing initial AIS met the inclusion criteria (mean age 69 years), with 57.7% (330/572) undergoing AUS and 42.3% (242/572) undergoing sling. The median duration of incontinence before AIS was 32 months. AUS patients pursued surgical intervention earlier than men undergoing sling (median time 28.8 months vs 34.7 months, P = .03). Most patients deferred AIS for more than 2 years (69.8% of sling patients and 58.5% of AUS patients), and 32.3% demonstrated an extended delay of more than 5 years. Increasing age correlated with delays in both AUS (Spearman rho = 0.20, P = .0001) and sling (Spearman rho = 0.34, P <.0001). On multivariate analysis, age was significantly associated with duration of incontinence (P <.0001). Octogenarians had a notably higher median delay of 87.4 months. CONCLUSION: Although the median duration of SUI before the initial AIS is 2.7 years, one-third of men experience a delay of more than 5 years. AUS present for AIS 6 months less on average relative to sling patients. Older men demonstrate a longer duration of SUI before seeking surgical care.

Improving Male Sling Selectivity and Outcomes-A Potential Role for Physical Demonstration of Stress Urinary Incontinence Severity?

INTRODUCTION: We reviewed our 9-year experience with AdVance™ Male Sling System cases to determine clinical features associated with treatment success and to refine procedure selectivity. We hypothesized that preoperative physical demonstration of stress urinary incontinence by the standing cough test improves patient selection for male sling surgery. METHODS: Retrospective review of primary AdVance sling surgeries between 2008 and 2016 was performed. Patients without standing cough test results were excluded from study. Success was defined as 1 pad per day or less postoperatively and no further intervention. Standing cough test was performed during preoperative consultation and objectively graded using the MSIGS (Male Stress Incontinence Grading Scale). RESULTS: Of the 203 male patients who underwent sling placement 80 (39%) experienced treatment failure during a median followup of 63.5 months. From 2008 to 2016 the proportion of AdVance slings performed as a surgical treatment modality for stress urinary incontinence decreased from 66% to 13%. Increasing selectivity correlated with greater treatment success. Success was greater among men using 2 pads per day or less preoperatively (77% vs 36%, p <0.0001), having physical findings of mild stress urinary incontinence (MSIGS grade 0-2 on standing cough test, 67% vs 26%, p <0.0001) and without a history of radiation (64% vs 41%, p=0.02). In combination, men without prior radiation with mild stress urinary incontinence and favorable standing cough test were "ideal patients" with an 81% success rate. Incremental increases in pad per day use (OR 1.8 per pad, p <0.0001) and MSIGS grade (OR 1.7 per grade, p=0.005) were independently associated with treatment failure. CONCLUSIONS: Increasing selectivity has improved sling outcomes for men with stress urinary incontinence. Ideal sling candidates have not received radiation therapy, and have history and physical findings suggestive of mild stress urinary incontinence.

Urethral Reconstruction in Aging Male Patients.

OBJECTIVE: To report stricture characteristics, complications, and treatment outcomes among elderly men undergoing urethral reconstruction. MATERIALS AND METHODS: A retrospective review of urethroplasty cases and outcomes by a single surgeon from 2007 to 2014 was performed. Men were stratified by decade of life at time of surgery (<50, 50-59, 60-69, ≥70 years). Individuals with a history of hypospadias were excluded. RESULTS: Among 514 urethroplasty procedures, 184 (36%) were evaluated in men ≥60 years. When stratified by decade of life, elderly men were more likely to have a history of radiation therapy (0% vs 5% vs 19% vs 50%; P <.0001) and experience treatment failure (6% vs 16% vs 20% vs 26%; P <.0001) during follow-up (median 63 months). The estimated 60-month stricture recurrence-free survival decreased with increasing age at time of urethroplasty (94% vs 89% vs 78% vs 74%; P <.0001). In patients ≥60 years, success rates of anastomotic, substitution, and urethrostomy techniques were 80%, 65%, and 88%; anastomotic urethroplasty success improved after excluding those patients with prior radiation. After surgery, elderly were more likely to have voiding dysfunction and <90-day Clavien ≥3 complications requiring endoscopic intervention. On multivariable analysis, advancing age per decade beyond 50 years was independently associated with risk of urethroplasty failure-50-59 (hazard ratio [HR] 2.39; P = .02), 60-69 (HR 2.80; P = .009), and ≥70 (HR 3.43; P = .003). CONCLUSION: Urethroplasty is safe and effective in the majority of elderly men. Early reconstructive intervention with anastomotic urethroplasty or urethrostomy techniques may optimize outcomes. Voiding dysfunction and prostatic obstruction are common in this population and should be pursued as clinically indicated.

Penile Plication as Salvage Strategy for Refractory Peyronie's Disease Deformities.

INTRODUCTION: We identified clinical and/or surgical factors contributing to failure of penile plication for Peyronie's reconstruction and assessed outcomes of repeat plications. METHODS: We conducted a retrospective review of patients who underwent penile plication between 2007 and 2016. Plication was performed after inducing an artificial erection intraoperatively using corrective longitudinal 2-zero Ethibond™ sutures placed systematically in a uniform manner without circumcision. Penile length, and angle and direction of curvature were recorded, along with number and location of plication sutures and clinical outcome. RESULTS: Of 340 patients undergoing penile plication during the study period 7 (2.1%) underwent repeat plication for insufficient straightening. Two additional patients underwent salvage plication after initial surgery performed elsewhere. Median time to revision was 6 months (range 3.4 to 27.4). The most common clinical features at reoperation were severe erectile dysfunction in 5 cases (71%), multiplanar curvature in 5 (71%) and severe curvature (60 degrees or greater) in 3 (43%). Most revisions involved a greater number of sutures during revision (mean 9) compared to initial plication (6), and in 4 cases (44%) sutures were placed on the proximal shaft. After revision all cases were noted to be functionally straight, with a mean postoperative curvature of 4 degrees (range 0 to 20) at a median followup of 27 months (3 to 76). CONCLUSIONS: Inadequate correction of Peyronie's disease curvature by penile plication is rare but salvageable by a second plication procedure. Poor erectile response to intracavernous injection intraoperatively may mask the severity of the deformity, thus leading to inadequate numbers of corrective sutures.

Improving Outcomes of Bulbomembranous Urethroplasty for Radiation-induced Urethral Strictures in Post-Urolume Era.

OBJECTIVE: To evaluate contemporary outcomes of excision and primary anastomosis (EPA) for the treatment of radiation-induced urethral strictures (RUS). PATIENTS AND METHODS: A retrospective review of 72 patients undergoing EPA for RUS from 2007 to 2015 by a single surgeon was performed. We analyzed overall and long-term success rates of EPA urethroplasty and compared patient cohorts from two groups, 2007-2012 vs 2013-2015 (post-Urolume). RESULTS: During the course of the study, we noted a near doubling of patient volume from the earlier (6.2 patients/year) to later (11.7 patients/year) cohorts. Among the 37 men treated from 2007 to 2012, we identified an EPA success rate of 70% compared with the improved 86% success rate in the subsequent cohort of 35 men treated from 2013 to 2015 (P = .07). Single dilation was successful in 50% of initial and 40% of subsequent cohort patients in the treatment of recurrence. Initial and subsequent cohorts varied only in regard to stricture length (mean 2.0 cm vs 3.0 cm in initial and subsequent cohorts, P = .001) and number treated with Urolume stent (initial 5 vs none in the later cohort, P = .03). Length of follow-up (median 50 [17-97] months for the initial and 22 [6-34] months for the later cohort) was not associated with recurrence. CONCLUSION: Increasing numbers of RUS patients are presenting for urethral reconstruction in the post-Urolume era. With increasing experience, we improved success rates of EPA urethroplasty to over 85% despite increased stricture length.

Characteristics of Idiopathic Urethral Strictures: A Link to Remote Perineal Trauma?

OBJECTIVE: To characterize the physical features and reconstructive outcomes of a series of idiopathic urethral strictures (IUS) in an effort to elucidate the nature of this common yet poorly understood entity. PATIENTS AND METHODS: We retrospectively reviewed our urethroplasty database to identify men undergoing initial urethral reconstruction from 2007 to 2014 at 1 of 3 hospitals (N = 514). Patients were stratified by stricture etiology, including IUS, acute trauma, iatrogenic, hypospadias, balanitis xerotica obliterans, and radiation. IUS that had a known history of subacute or repetitive blunt force to the perineum (horseback riding, avid cycling, motocross, etc.) were subclassified as subacute or repetitive perineal trauma (SRPT). RESULTS: Among 466 men undergoing initial reconstruction with available data, 215 (46%) were IUS cases. The median delay between IUS diagnosis and urethroplasty was 5.2 years, during which time men underwent a median of 2 endoscopic treatments. A total of 51 (24%) IUS cases recalled a distinct history of SRPT. Men with SRPT were slightly younger (median 43 vs 48 years, P = .01) but were remarkably similar in terms of urethral stricture length (2 vs 2 cm, P = .15), location (bulbar 96% vs 89%, P = .41), and treatment success (92% vs 88%; P = .61). Bulbar (-)SRPT and (+)SRPT IUS had similar clinical and morphometric features as those with known acute bulbar trauma with excellent 24-month stricture recurrence-free survival rates (93% vs 92% vs 97%, P = .19). CONCLUSION: IUS have clinical features suggesting that many may be related to unrecognized or repetitive perineal trauma. Although treatment tends to be delayed, IUS have excellent urethroplasty success because most are short bulbar strictures amenable to anastomotic urethroplasty.

Low Testosterone Levels Result in Decreased Periurethral Vascularity via an Androgen Receptor-mediated Process: Pilot Study in Urethral Stricture Tissue.

OBJECTIVE: To compare expression of androgen receptor (AR) and angiopoietin 1 receptor TIE-2 and vessel density of urethral stricture tissue among eugonadal and hypogonadal men to identify a pathophysiological basis for our observations that low testosterone is associated with urethral atrophy. METHODS: Among 1200 men having urethroplasty at our institution, we retrospectively identified 11 patients with testosterone levels drawn within 2 years of surgery. Low testosterone was defined as <280 ng/dL and detected in 5 of 11 (45.5%) patients. Urethral tissue samples were analyzed using immunohistochemistry for AR, TIE-2 (a downstream target of activated AR linking it to angiogenesis), and CD31 expression. RESULTS: Mean testosterone was 179.4 ng/dL for patients classified as having low testosterone and 375.0 ng/dL for controls (P = .003). We found a significant decrease of AR expression (1.11%high power field [HPF] vs 1.62, P = .016), TIE-2 expression (1.84%HPF vs 3.08, P = .006), and vessel counts (44.47 vessels/HPF vs 98.33, P = .004) in men with low testosterone. Expression levels of AR and TIE-2 were directly correlated to testosterone levels (rho: 0.685, P = .029, and rho: 0.773, P = .005, respectively). We did not find a difference in age, radiation, or comorbidities among patients with normal or low testosterone levels, with the exception of higher body mass index in the latter. CONCLUSION: Men with low testosterone levels demonstrate decreased AR and TIE-2 expression and lower vessel counts in periurethral tissue samples of urethral strictures. Our results provide a rationale for a mechanistic relationship between low testosterone levels and decreased periurethral vascularity that may contribute to urethral atrophy in patients with urethral strictures.

Role of Chronic Suprapubic Tube in the Management of Radiation Induced Urethral Strictures.

INTRODUCTION: We examined the role of chronic suprapubic tube drainage in patients with radiation induced urethral stricture disease. METHODS: A retrospective review was performed of patients undergoing evaluation and treatment of radiation induced urethral stricture. Differences in patient and stricture characteristics among those treated with chronic suprapubic tube vs urethral reconstruction were evaluated. RESULTS: Among 75 patients who received suprapubic tube for radiation induced urethral stricture 37 (49%) selected chronic suprapubic tube and 38 (51%) ultimately underwent urethroplasty. Mean age was 70.9 years and mean followup was 25.3 months after suprapubic tube placement. Preoperative stress urinary incontinence improved after suprapubic tube placement in 20 of 33 (61%) patients. Accordingly, men with stress urinary incontinence were significantly more likely to be treated with chronic suprapubic tube (73%) compared to those proceeding to reconstruction (27%, p <0.001). Among those with persistent stress urinary incontinence after suprapubic tube, 11 of 16 (69%) underwent artificial urinary sphincter placement (urethroplasty 3 of 3 vs chronic suprapubic tube 8 of 13, p=0.19). On multivariable analysis the lack of preoperative stress urinary incontinence remained predictive of proceeding to reconstruction (OR 0.17, 95% CI 0.06-0.49, p=0.001). Among patients treated with chronic suprapubic tube, complications including stone formation or urinary urgency were reported in 27%. CONCLUSIONS: Although radiation induced urethral stricture can usually be managed effectively with urethroplasty, chronic suprapubic tube remains a viable management option, especially for men with preoperative stress urinary incontinence.

Clinical Risk Factors Associated With Urethral Atrophy.

OBJECTIVE: To analyze a series of clinical risk factors associated with pretreatment urethral atrophy. METHODS: We retrospectively reviewed 301 patients who underwent artificial urinary sphincter (AUS) placement between September 2009 and November 2015; of these, 60 (19.9%) transcorporal cuff patients were excluded. Patients were stratified into 2 groups based on intraoperative spongiosal circumference measurements. Men with urethral atrophy (3.5 cm cuff size) were compared to controls (≥4 cm cuff size). Chi-square test, Mann-Whitney U test, and logistic regression analyses were performed to determine risk factors for urethral atrophy. RESULTS: Among 241 AUS patients analyzed, urethral atrophy was present in 151 patients (62.7%) compared to 90 patients (37.3%) who received larger cuffs (range 4-5.5 cm). Patients with urethral atrophy were older (71.1years vs 68.3 years; P < .02), more likely to have received radiation (52.9% vs. 33.3%; P < .007), and had a longer time interval between prostate cancer treatment and AUS surgery (8.9 years vs. 6.6 years; P < .033). On multivariable analysis, radiation therapy was independently associated with risk of urethral atrophy (odds ratio 1.77, 95% confidence interval: 1.01-3.13; P = .046), whereas greater time between cancer therapy and incontinence surgery approached clinical significance (odds ratio 1.05, 95% confidence interval 1.00-1.09; P = .05). CONCLUSION: History of radiation therapy and increasing length of time from prostate cancer treatment are associated with urethral atrophy before AUS placement.
