RESUMO
PURPOSE: We sought to determine whether patients discharged from the hospital without antibiotics after inflatable penile prosthesis insertion were at increased risk for infectious complications compared to patients at our institution discharged with oral antibiotics and patients in other contemporary series. MATERIALS AND METHODS: We reviewed the medical records of patients who underwent inflatable penile prosthesis insertion from 2013 through 2017. Group 1 patients had no risk factors for infectious complications and did not receive postoperative antibiotics. Group 2 patients had risk factors for infectious complications but did not receive postoperative antibiotics. Group 3 patients had risk factors for infectious complications and received postoperative antibiotics. RESULTS: Of the 222 men who met study inclusion criteria 88 (40%) were in group 1, 48 (21%) were in group 2 and 86 (39%) were in group 3. The mean ± SD number of risk factors for infection was lower in group 2 than in group 3 (1.08 ± 0.28 vs 1.24 ± 0.46, p = 0.013). Median followup did not vary among groups 1, 2 and 3 (4.6 months, IQR 1.8-7.2; 3.5, IQR 1.4-6.9; and 4.5, IQR 1.4-7.4; p = 0.146, respectively). Rates of explantation due to device infection (0% vs 4% vs 5%, p = 0.130) and nonoperative infectious complications (1% vs 2% vs 2%, p = 0.829) did not vary among groups 1 to 3, respectively. CONCLUSIONS: Patients who undergo inflatable penile prosthesis insertion appeared unlikely to benefit from routine administration of postoperative antibiotics. In the current era of antibiotic stewardship these findings have the potential for substantial individual and population health benefits.

INTRODUCTION We sought to explore whether patients discharged without antibiotics after artificial urinary sphincter (AUS) insertion were more likely to require device explantation for infection or erosion compared to patients discharged with antibiotics at our institution and compared to patients in other large, contemporary series. MATERIALS AND METHODS: AUS insertions performed at our institution between 2013 and 2017 were retrospectively reviewed to determine demographics, comorbidities, and perioperative and medium-term outcomes. Patients were grouped based on 1) known risk factors for infectious complications or erosion and 2) postoperative antibiotic prescription status. Patients were placed in Group 1 if they did not demonstrate risk factors and did not receive postoperative antibiotics, Group 2 if they did possess risk factors but did not receive postoperative antibiotics, and Group 3 if they had risk factors and received postoperative antibiotics. RESULTS: Of the 155 men who met inclusion criteria, 44, 47, and 64 were categorized in Groups 1, 2, and 3, respectively. Median (IQR) follow up was similar across Groups 1, 2, and 3 (12.7 [4.6-25.1] versus 10.7 [4.5-31.3] versus 8.3 [4.4-26.4] months, p = 0.808). Rates of explantation due to device infection (0 versus 2 versus 6%, p = 0.172) or cuff erosion (2 versus 2 versus 8%, p = 0.253) did not vary significantly between Groups 1-3. CONCLUSIONS: Patients undergoing AUS insertion may be unlikely to benefit from the routine administration of postoperative antibiotics. In light of the known consequences of antibiotic overuse, a randomized controlled trial is warranted.

PURPOSE: Substantial controversy and conflicting data exist regarding the survival of the artificial urinary sphincter in patients with prior radiation therapy. We present data from a multi-institutional analysis examining the effect of prior radiation for prostate cancer on device survival. MATERIALS AND METHODS: A database was compiled of patients with artificial urinary sphincter cuff erosion, which included demographic and comorbid patient characteristics, functional analyses and interventions. We identified 80 patients with iatrogenic or idiopathic artificial urinary sphincter erosion. Idiopathic erosion cases were further analyzed to determine factors influencing device survival with specific stratification for radiation therapy. RESULTS: A total of 56 patients were identified with idiopathic artificial urinary sphincter erosion. Of those men 33 (58.9%) had not undergone radiation treatment while 23 (41.1%) had a history of brachytherapy or external beam radiotherapy. In patients without radiation erosion-free median device survival was 3.15 years (95% CI 1.95-5.80), in contrast to the median device survival of only 1.00 year (95% CI 0.36-3.00) in irradiated patients. The erosion-free survival experience of patients with vs without radiation differed significantly (Wilcoxon-Breslow test for equality of survivor functions p = 0.03). CONCLUSIONS: Radiation therapy in patients with known idiopathic cuff erosion in this contemporary analysis correlated with significantly increased time to erosion. Mean time to idiopathic cuff erosion was accelerated by approximately 2 years in irradiated cases. To our knowledge these data represent the first demonstration of substantial outcome differences associated with radiation in patients with an artificial urinary sphincter who present specifically with cuff erosion.

PURPOSE: Many providers elect to use a transcorporeal approach for artificial urinary sphincter placement in an attempt to minimize risks, given the increased risk of complications in revision cases. We present outcomes in a multicenter retrospective analysis of artificial urinary sphincter cuff reimplantation in patients with prior cuff erosion with special consideration given to the transcorporeal approach. MATERIALS AND METHODS: We compiled a multi-institutional database of patients who underwent artificial urinary sphincter reimplantation after prior urethral erosion. Of the 34 identified patients 24 underwent transcorporeal cuff replacement. Patients with transcorporeal cuff replacement were further analyzed with specific stratification for radiation therapy. RESULTS: The rate of subsequent complications after eroded cuff reimplantation was 32.4% (11 of 34 patients). The most frequent complication was recurrent erosion, which developed in 9 of the 34 patients (26.4%). Repeat artificial urinary sphincter complications developed more frequently in patients with history of radiation compared to nonirradiated patients (8 of 16 or 50% vs 3 of 18 or 16.7%). However, this difference was not statistically significant (p = 0.066). The transcorporeal technique was applied in 24 of 33 patients (70.5%) and relative to the nontranscorporeal group there was no difference in the complication rate (p = 0.438). On subgroup analysis of the transcorporeal group there was a higher rate of repeat complications in irradiated patients (p = 0.006). CONCLUSIONS: These data suggest that transcorporeal cuff reimplantation may not decrease the incidence of repeat complications after prior cuff erosion. However, radiation therapy is associated with a worse outcome even when transcorporeal cuff placement is performed.

PURPOSE: To compare the cost-effectiveness of various treatment strategies in the management of pelvic fracture urethral injuries using decision analysis. METHODS: Five strategies were modeled from the time of injury to resolution of obstructed voiding or progression to urethroplasty. Management consisted of immediate suprapubic tube (SPT) placement and delayed urethroplasty; primary endoscopic realignment (PER) followed by urethroplasty in failed patients; or PER followed by 1-3 direct vision internal urethrotomies (DVIU), followed by urethroplasty. Success rates were obtained from the literature. Total medical costs were estimated and incremental cost-effectiveness ratios (ICERs) were generated over a 2-year follow-up period. RESULTS: PER was preferred over SPT placement in all iterations of the model. PER followed by a single DVIU and urethroplasty in cases of failure was least costly and used as the referent approach with an average cost-effectiveness of $17,493 per unobstructed voider. The ICER of a second DVIU prior to urethroplasty was $86,280 per unobstructed voider, while the ICER of a third DVIU was $172,205. The model was sensitive to changes in the success rate of the first DVIU, where when the probability of DVIU success is expected to be less than 32% immediate urethroplasty after failed PER is favored. CONCLUSIONS: Management of pelvic fracture urethral injuries with PER is the preferred management strategy according to the current model. For those who fail PER, a single DVIU may be attempted if the presumed success rate is >32%. In all other cases, urethroplasty following PER is the preferred approach.

AIMS: Postural Tachycardia Syndrome (POTS) represents an autonomic disorder predominantly affecting females between 15 and 50 years of age. POTS is a chronic disorder (>6 months) characterized by an excessive heart rate increment on standing (>30 beats/min) in the presence of characteristic symptoms of cerebral hypoperfusion or sympathetic activation. Patients have clinically been noted to describe lower urinary tract symptoms (LUTS), although urologic symptoms have not been methodically assessed in the POTS population. Herein, we present data from a pilot study designed to identify and quantitate overactive bladder (OAB) in patients diagnosed with POTS. METHODS: Patients admitted to the Vanderbilt Autonomic Dysfunction Center between June 2009 and October 2010 for evaluation for the potential diagnosis of POTS completed a validated, standardized questionnaire for OAB (OAB-q) at presentation. Symptom score and subscale analyses were conducted. Subscale health related quality of life (HRQL) scores were transformed into a 0-100 scale, with higher scores reflecting superior HRQL. Data are presented as mean ± SD. RESULTS: Thirty-two females presented for evaluation of symptoms consistent with POTS. Twenty-nine women were subsequently diagnosed with POTS with 19 of these patients completing the OAB-q questionnaire (65.5% response rate). Average age was 33.5 ± 8.3 years. Symptom severity transformed score was 26.0 ± 16.4, with 13 of 19 patients (68.4%) meeting clinical criteria for diagnosis of probable clinically significant OAB. Nocturia was the most bothersome symptom, followed by increased daytime frequency and urgency. CONCLUSIONS: This pilot study describes bothersome lower urinary tract dysfunction in patients presenting with POTS as assessed by patient-reported questionnaire data. Nocturia demonstrated the greatest negative impact on health-related quality of life (HRQL), while social interaction was the least affected HRQL domain. In patients with dysautonomia, this data provides a critical baseline for mechanistic insight into both disease-specific and global pathophysiology of nocturia and OAB. Neurourol.

AIMS: Beyond single-institution case series, limited data are available to describe risks of performing a concurrent cystectomy at the time of urinary diversion for benign end-stage lower urinary tract dysfunction. Using a population-representative sample, this study aimed to analyze factors associated with perioperative complications in patients undergoing urinary diversion with or without cystectomy. METHODS: A representative sample of patients undergoing urinary diversion for benign indications was identified from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample from 1998 to 2011. Perioperative complications of urinary diversion with and without concomitant cystectomy were identified and coded using the International Classification of Diseases, version 9. Multivariate logistic regression models identified hospital and patient-level characteristics associated with complications of concomitant cystectomy with urinary diversion. RESULTS: There were 15,717 records for urinary diversion identified, of which 31.8% demonstrated perioperative complications: urinary diversion with concurrent cystectomy (35.0%) and urinary diversion without concomitant cystectomy (30.6%). Comparing the two groups, a concomitant cystectomy at the time of urinary diversion was significantly associated with a complication (OR = 1.23, 95%CI: 1.03-1.48). Comorbid conditions of obesity, pulmonary circulation disease, drug abuse, weight loss, and electrolyte disorders were positively associated with a complication, while private insurance and southern geographic region were negatively associated. CONCLUSIONS: A concomitant cystectomy with urinary diversion for refractory lower urinary tract dysfunction elevates risk in this population-representative sample, particularly in those with certain comorbid conditions. This analysis provides critical information for preoperative patient counseling.

PURPOSE: Catheter drainage has become a standard management strategy for extraperitoneal bladder rupture from blunt trauma. However, data are lacking critically comparing outcomes between operative and nonoperative management. In this study we evaluate management strategies and identify risk factors for complications. MATERIALS AND METHODS: Patients with uncomplicated extraperitoneal bladder rupture due to blunt trauma from 2000 to 2014 were identified from our trauma registry. Initial management consisted of early cystorrhaphy or catheter drainage. Outcomes analyzed were incidence of inpatient complications, length of stay and time to negative cystography. Subgroup analysis was performed comparing outcomes between patients who did vs did not undergo cystorrhaphy during nonurological operative intervention. RESULTS: A total of 56 patients treated with catheter drainage and 24 who underwent early cystorrhaphy were identified. All early cystorrhaphies were performed as secondary procedures during nonurological interventions. There was no difference in demographics, complications, median intensive care unit or median hospital length of stay between the groups. Subgroup analysis comparing patients who did vs did not undergo cystorrhaphy during nonurological operative intervention showed that patients without cystorrhaphy experienced higher rates of urological complications (p <0.05), increased intensive care unit (9.0 vs 4.0 days, p=0.0219) and hospital (18.9 vs 10.6 days, p=0.0229) length of stay, as well as prolonged time to negative cystography (25.5 vs 20.0 days, p=0.0262). CONCLUSIONS: Conservative management of simple extraperitoneal bladder rupture with catheter drainage alone results in equivalent outcomes relative to operative repair in most patients. However, for those undergoing operations for other indications, cystorrhaphy decreases the risk of complications and is associated with decreased intensive care unit and hospital length of stay.

PURPOSE: Controversy remains regarding initial management of traumatic urethral disruption injuries. We evaluated the outcomes of primary endoscopic realignment vs suprapubic tube placement in this patient population. MATERIALS AND METHODS: We reviewed our urological trauma database for patients with blunt trauma related posterior urethral injuries from 2000 to 2014. Patients underwent primary endoscopic realignment or suprapubic tube placement alone. The primary outcome was the success of primary realignment, defined as no further need for urological intervention. Secondary outcomes were the need for endoscopic interventions and/or urethroplasty, time to urethroplasty, urethroplasty success and long-term functional outcomes. RESULTS: A total of 27 patients underwent primary realignment and 14 underwent suprapubic tube placement. Mean followup was 40 months (median 24, range 1 to 152). Realignment was successful in 10 patients (37%) at a mean followup of 67.3 weeks (median 27.3, range 4 to 284). In the 17 cases (63%) that failed mean time to failure was 9.7 weeks (median 8.5, range 1 to 26). Seven patients (26%) treated with realignment and 11 (79%) with a suprapubic tube proceeded to urethroplasty. Mean ± SD time to urethroplasty was significantly shorter in the suprapubic tube group (14.6 ± 7.6 vs 5.8 ± 1.6 months, p = 0.003). There was no difference in operative time, complications, success or functional outcomes. CONCLUSIONS: Management of traumatic urethral disruption injuries by primary endoscopic realignment serves as definitive therapy in more than a third of treated patients. It prevents the need for formal urethroplasty in more than half of failed cases.

PURPOSE: We report the impact of urethral risk factors on erosion rates and device survival outcomes after transcorporeal artificial urinary sphincter placement. MATERIALS AND METHODS: We performed a retrospective analysis of all transcorporeal artificial urinary sphincters placed at a single institution between January 2000 and May 2014. We assessed patient demographic, comorbid diseases and surgical characteristics for risk factors considered poor for device survival. Risk factors were compared to postoperative complications requiring explantation, including cuff erosion, infection and device revision. RESULTS: A total of 37 transcorporeal artificial urinary sphincters were placed in 35 men. Placement was performed as a primary procedure in 21 of 37 cases (56.8%) and as salvage in the remainder. In this transcorporeal population there were 7 explantations (18.9%) due to erosion in 4 cases, cuff downsizing in 2 and infection in 1. Median followup from implantation to last followup was 8.5 months (range 0.9 to 63). Median time from artificial urinary sphincter placement to explantation was 17.3 months (range 0.9 to 63) and time specifically to transcorporeal erosion was 7.4 months (range 0.9 to 26). On univariate analysis no parameters were associated with sphincter cuff erosion but a history of an inflatable penile prosthesis was associated with a higher device explantation rate (60% vs 12.5%, p=0.04). No associations were revealed on multivariate logistic analysis. All 4 cuff erosion cases demonstrated greater than 2 urethral risk factors, including prior radiation therapy in all. The probability of cuff erosion in patients with 2 or more urethral risk factors was 1.65 times the probability of erosion in those with 0 or 1 urethral risk factor (95% CI 1.3, 2.2). The proportion of patients free of erosion at 35 months was 100% in those with 0 or 1 urethral risk factor and 64% in those with 2 or more risk factors (log rank test p=0.00). Similarly the proportion of patients free of explantation at 35 months was 100% in those with 0 or 1 urethral risk factor and 52% in those with 2 or more (log rank test p=0.02). CONCLUSIONS: Transcorporeal artificial urinary sphincter implantation is generally reserved for complex and high risk cases but favorable functional results were demonstrated. However, patients with multiple urethral risk factors face a higher risk of erosion and device loss.

PURPOSE: We assessed whether a difference between intraoperative urethral circumference and artificial urinary sphincter cuff size affects postoperative outcomes. MATERIALS AND METHODS: We evaluated the medical records of 87 males who underwent implantation of an artificial urinary sphincter between January 2006 and May 2010. A validated questionnaire was completed by 59 patients for long-term followup. The difference between urethral circumference and artificial urinary sphincter cuff size was calculated. Incontinence was recorded as daily pad use. The primary outcome variable was the postoperative decrease in incontinence. Multivariable linear regression was used to model the effect on postoperative incontinence of the difference between urethral circumference and cuff size. RESULTS: Mean long-term followup was 4.2 years. Median preoperative incontinence was 8 pads per day and median abdominal leak point pressure was 50 cm H2O. Median urethral circumference was 38 mm and the median difference between urethral circumference and artificial urinary sphincter cuff size was 2.5 mm. Median postoperative incontinence was 1 pad per day. A 1 mm increase in the difference between urethral circumference and cuff size resulted in a 1.6% increase in incontinence by 4.5 months postoperatively (95% CI -3.1-6.2, p = 0.487). Paradoxically, each 1 mm increase improved postoperative continence at long-term followup by 29% (95% CI -15-56, p = 0.162). CONCLUSIONS: At 4.5-month followup there was no statistical difference in pad use or patient satisfaction when the difference between urethral circumference and artificial urinary sphincter cuff size was less than 4 mm vs 4 mm or greater. However, at long-term followup the 4 mm or greater group reported statistically significantly better continence and satisfaction than the less than 4 mm group. This study does not support efforts to improve continence by minimizing cuff size but rather suggests that modestly up-sizing the cuff may produce improved long-term outcomes.

OBJECTIVE: To determine whether a patient's health literacy impacts patient satisfaction following inflatable penile prosthesis (IPP) or artificial urinary sphincter (AUS) placement. MATERIALS AND METHODS: A retrospective study of patients who underwent IPP or AUS between January 1, 2016 and July 31, 2020 was performed. A telephone questionnaire assessed overall satisfaction and if patients would undergo surgery again. Health literacy was measured using the Brief Health Literacy Screen (BHLS). Multivariate ordinal logistic regression was used to assess the association between health literacy and patient satisfaction. RESULTS: At a median follow up of 2.4 years, 113 (70%) of the 162 IPP patients were either satisfied or very satisfied with their procedure and 120 (74%) patients would undergo surgery again. Of the 76 AUS patients, 65 (86%) were either satisfied or very satisfied with their procedure and 65 (86%) patients would undergo surgery again. After adjustment for potential confounders, increasing BHLS score was significantly associated with satisfaction for both IPP (OR 1.31, 95% CI 1.11-1.54; Pâ¯=â¯.001) and AUS surgery (OR 1.25, 95% CI 1.02-1.56; Pâ¯=â¯.034), as well as with likelihood of undergoing IPP surgery again (OR 1.53, 95% CI 1.25-1.87; P <.001). BHLS was not associated, however, with likelihood of undergoing AUS surgery again (Pâ¯=â¯.403). CONCLUSION: Men with lower health literacy are less likely to be satisfied following prosthetic surgery. The BHLS is an important tool that can be used to identify patients who may benefit from increased preoperative counseling to improve patient expectations and quality of life following prosthetic surgery.

PURPOSE: Treatment options for antimuscarinic refractory neurogenic detrusor overactivity (NDO) are botulinum toxin type A injections (BTX-A) and augmentation cystoplasty (AC). We estimated initial and cumulative 5-year costs of these treatments. MATERIALS AND METHODS: Base case is an individual with antimuscarinic refractory NDO and decreased bladder compliance. Primary analysis is from the health care payor perspective. Model probabilities and ranges were derived from literature and chart review. Reimbursements were derived from the average of insurance carriers. Complication cost calculations were based on standard practice. Decision-analysis model was made with TreeAge Pro Healthcare 2009 Software, Inc. and rolled back for cost calculation. One-way sensitivity analysis was performed on all variables, and two-way sensitivity analyses were based on these results. RESULTS: Average reimbursement for one BTX-A injection and AC was $2,946.83 and $25,041.53, respectively. BTX-A treatment was less expensive over 5 years, costing $28,065. The model was only sensitive within a reasonable clinical range for Botox durability. BTX-A was more cost-effective over 5 years if the effect lasted for >5.1 months. The model was based on an AC complication rate of 40%. If the PAC complication rate<14%, AC was cheaper over 5 years. The model was sensitive to surgeons costs of BTX-A ($3,027) and facility costs of BTX-A ($1,004) and AC ($17,100). CONCLUSIONS: This is the first cost analysis of BTX-A and AC. BTX-A is cheaper at durations>5.1 months and AC was cheaper when the cost of BTX-A increases or the AC complication rate dropped below 14%.

STUDY TYPE: Therapy (case series) Level of Evidence 4. OBJECTIVE: To report the indications and outcomes of a contemporary series of patients with contraindications to percutaneous renal biopsies (PRBs) who had an operative RB (ORB), as although ORB is a relatively infrequent procedure, it remains an important and underreported operation. PATIENTS AND METHODS: In a retrospective review of patients who had an ORB we examined comorbidities, indications, and 30-day morbidity and mortality. Preoperative comorbidities were stratified according to the Charlson comorbidity index. RESULTS: In all, 115 patients had ORB between 1991 and 2006 (mean age 48 years, range 18-83); 60% of the patients were American Society of Anesthesiologists class >or=3. The median Charlson comorbidity index score was 3, with a score of 0 in 20.9%, 1-2 in 27.8%, 3-4 in 30.4% and >or=5 in 20.9% of patients. Indications for an ORB included morbid obesity, failed PRB, coagulopathy, and solitary kidney. In all, 47.8% of patients had a serum creatinine level of <3.0 mg/dL, 34.8% of >3.0 mg/dL and 17.4% were dialysis-dependent. There were 43 complications in 36 patients. The mortality rate after surgery was 0.8%. There were eight major complications in seven patients (6.1%) including cardiac arrest, stroke, sepsis, reoperation and re-intubation. There were minor complications 34 times in 31 patients (27%), the most common being wound infection, pneumonia, intraoperative transfusion of >2 units, arrhythmia, postoperative retroperitoneal bleed, and seep vein thrombosis. CONCLUSIONS: This study shows that there are significant comorbidities in patients referred to urologists for an ORB. With a mortality rate of 0.8% and major and minor complication rates of 6.1% and 27%, respectively, the ORB, while infrequent, carries a significant risk in this population that should be included in preoperative decision making and used for patient counselling.

INTRODUCTION: With more than 3,500 artificial urinary sphincters placed annually in the United States a significant cost burden is associated with overnight observation following surgery. We sought to determine whether inpatient management after artificial urinary sphincter insertion, our current local standard of care, is necessary with regards to inpatient narcotic requirements and immediate postoperative complications. METHODS: This was an institutional review board approved, retrospective review of artificial urinary sphincter insertions identified by CPT code 53445 between June 2013 and September 2017. Medical records were reviewed for patient demographics, postoperative narcotic use and immediate postoperative complications. RESULTS: We identified 163 men who underwent artificial urinary sphincter insertion for analysis. The cohort had a mean age of 69.8 ± 8.5 years, body mass index of 28.9 ± 5.1 kg/m2 and preoperative pad per day use of 5.8 ± 3.5. Of all patients identified 25 (15%) were using chronic narcotic pain medication preoperatively and 51 (31%) had a diagnosis of diabetes (mean A1c 7.0 ± 1.5%). All but 1 (99%) patients were discharged on the first postoperative day and 1 left on the second postoperative day. Two (1.2%) patients experienced immediate postoperative complication, and 8 (6%) patients failed a voiding trial on postoperative day 1. The 154 (94%) patients who required orally administrated narcotic pain medication after leaving the postanesthesia care unit used a median of 31.0 ± 22.9 morphine milligram equivalents. CONCLUSIONS: Immediate postoperative and peridischarge complication rates are around 1% after artificial urinary sphincter insertion, and narcotic requirements following postanesthesia care unit stay are minimal. Outpatient artificial urinary sphincter insertion is likely to be safe, effective and beneficial with regards to patient experience and total costs.
RESUMO
INTRODUCTION: Although pelvic fracture urethral injuries (PFUIs) are rare, approximately half these patients will report erectile dysfunction (ED) after their injuries. The anatomic relations of the cavernosal nerves and arteries to the bones of the pelvis and the urethra put these structures at significant risk at the time of PFUI. This review examines the epidemiology, evaluation, and management of ED in this patient population. AIM: To evaluate the epidemiology, pathophysiology, diagnosis, and management of patients with ED after PFUI. METHODS: A literature review was performed to identify articles on PubMed published before May 2017 addressing PFUI and ED. MAIN OUTCOME MEASURES: Incidence, mechanisms, risk factors, evaluation, and management strategies of ED after PFUI were analyzed. RESULTS: Patients with pelvic fractures are at risk of post-injury ED, whereas those with PFUI appear to be at even higher risk. Different potential mechanisms contributing to the pathophysiology of ED in this setting have been described in the literature, including damage to the nervous supply to the penis, arterial insufficiency, and veno-occlusive dysfunction. However, there is a lack of consensus on the predominant etiology. Appropriate diagnostic evaluation can help to elucidate the underlying pathophysiology on an individual basis and can help guide management. Oral therapies, intracavernosal injections, and inflatable penile prostheses have shown great success. Furthermore, unlike patients with ED from other causes, select patients with isolated arteriogenic ED are potentially eligible for penile revascularization procedures. CONCLUSION: Because most patients with pelvic trauma are younger than 40 years with a significant life expectancy, appropriate diagnosis and management of ED after PFUI can greatly improve quality of life and allow resumption of post-injury sexual function. Identification of the causative pathology can help tailor treatment on an individual basis. Johnsen NV, Kaufman MR, Dmochowski RR, Milam DF.

BACKGROUND: Benign prostatic hyperplasia is commonly treated with alpha-adrenergic-receptor antagonists (alpha-blockers) or 5alpha-reductase inhibitors. The long-term effect of these drugs, singly or combined, on the risk of clinical progression is unknown. METHODS: We conducted a long-term, double-blind trial (mean follow-up, 4.5 years) involving 3047 men to compare the effects of placebo, doxazosin, finasteride, and combination therapy on measures of the clinical progression of benign prostatic hyperplasia. RESULTS: The risk of overall clinical progression--defined as an increase above base line of at least 4 points in the American Urological Association symptom score, acute urinary retention, urinary incontinence, renal insufficiency, or recurrent urinary tract infection--was significantly reduced by doxazosin (39 percent risk reduction, P<0.001) and finasteride (34 percent risk reduction, P=0.002), as compared with placebo. The reduction in risk associated with combination therapy (66 percent for the comparison with placebo, P<0.001) was significantly greater than that associated with doxazosin (P<0.001) or finasteride (P<0.001) alone. The risks of acute urinary retention and the need for invasive therapy were significantly reduced by combination therapy (P<0.001) and finasteride (P<0.001) but not by doxazosin. Doxazosin (P<0.001), finasteride (P=0.001), and combination therapy (P<0.001) each resulted in significant improvement in symptom scores, with combination therapy being superior to both doxazosin (P=0.006) and finasteride (P<0.001) alone. CONCLUSIONS: Long-term combination therapy with doxazosin and finasteride was safe and reduced the risk of overall clinical progression of benign prostatic hyperplasia significantly more than did treatment with either drug alone. Combination therapy and finasteride alone reduced the long-term risk of acute urinary retention and the need for invasive therapy.

INTRODUCTION: Sacral neuromodulation (SNM) remains one of the few effective treatments for refractory bladder and bowel dysfunction. However, SNM is associated with frequent need for surgical intervention, in many cases because of a failed battery. A rechargeable SNM system, with a manufacturer-reported battery life of 15 years or more, has entered post-market clinical testing in Europe but has not yet been approved for clinical testing in the United States. Areas covered: We review existing neuromodulation technologies for the treatment of lower urinary tract and bowel dysfunction and explore the limitations of available technology. In addition, we discuss implantation technique and device specifications and programming of the rechargeable SNM system in detail. Lastly, we present existing evidence for the use of SNM in bladder and bowel dysfunction and evaluate the anticipated trajectory of neuromodulation technologies over the next five years. Expert commentary: A rechargeable system for SNM is a welcome technological advance. However surgical revision not related to battery changes is not uncommon. Therefore, while a rechargeable system would be expected to reduce costs, it will not eliminate the ongoing maintenance associated with neuromodulation. No matter the apparent benefits, all new technologies require extensive post-market monitoring to ensure safety and efficacy.

BACKGROUND: Urethroplasty is often successful for the treatment of male urethral stricture disease, but limited data exists on recurrence management. Our goal was to evaluate direct visual internal urethrotomy (DVIU) as a treatment option for isolated, recurrent strictures after urethroplasty. METHODS: We retrospectively identified male patients who underwent urethroplasty from 1999 to 2013 and developed an isolated, recurrent stricture at the urethroplasty site treated with DVIU. Success was defined as lack of symptomatology and no subsequent intervention. Comparative analysis identified characteristics and stricture properties associated with success. RESULTS: A total of 436 urethroplasties were performed in 401 patients at our institution between 1999 and 2013. Stricture recurrence was noted in 64 (16%) patients. Of these, 47 (73%) underwent a DVIU. A total of 37 patients met inclusion criteria and underwent 50 DVIU procedures at the urethroplasty site. A single DVIU was successful in 13 of 37 patients (35%). A total of 4 of 6 patients required a second DVIU (67%). Overall, 17 of 43 (40%) of the total DVIUs were successful after urethroplasty. Success did not differ by age, stricture length or location, surgical technique, radiation history, prior urethroplasty or DVIU, time to failure, or etiology. CONCLUSIONS: Post-urethroplasty DVIU for isolated, recurrent strictures may be offered as a minimally invasive treatment option. Approximately 40% of patients were spared further intervention.
