Prior male sling does not affect outcomes of artificial urinary sphincter.

OBJECTIVE: To investigate the outcomes of artificial urinary sphincter (AUS) placement in patients with post-prostatectomy urinary incontinence (PPUI) with or without a prior male sling. PATIENTS AND METHODS: We performed a retrospective chart review of patients who underwent AUS for PPUI from 2007 to 2022. The primary endpoint was to determine the proportion of patients who achieved social continence, defined as self-reported use of 0-1 pad/day. The secondary endpoints were device failure rates and device failure-free survival. RESULTS: The analysis included 210 patients, with 30 (14.3%) having had prior slings and 180 (85.7%) without prior slings. After AUS insertion, 80.0% of patients with prior slings and 76.7% of those without prior slings achieved continence (0-1 pad/day). There were six (20.0%) and 53 (29.4%) device failures in patients with and without prior slings, respectively. The median device failure-free survival was not reached in patients with prior slings and was 8.9 years in patients without prior slings (P = 0.048). Limitations include retrospective nature and small sample size. CONCLUSIONS: The efficacy and safety of AUS in patients with prior slings are similar to those without. Prior sling is associated with a longer device failure-free survival. AUS remains a viable option in patients who have persistent PPI after prior slings.

Penile prostheses harbor biofilms driven by individual variability and manufacturer even in the absence of clinical infection.

BACKGROUND: Culture-based studies have shown that penile prostheses harbor biofilms in the presence and absence of infection, but these findings have not been adequately validated using contemporary microbiome analytic techniques. AIM: The study sought to characterize microbial biofilms of indwelling penile prosthesis devices according to patient factors, device components, manufacturer, and infection status. METHODS: Upon penile prostheses surgical explantation, device biofilms were extracted, sonicated, and characterized using shotgun metagenomics and culture-based approaches. Device components were also analyzed using scanning electron microscopy. OUTCOMES: Outcomes included the presence or absence of biofilms, alpha and beta diversity, specific microbes identified and the presence of biofilm, and antibiotic resistance genes on each prosthesis component. RESULTS: The average age of participants from whom devices were explanted was 61 ± 11 years, and 9 (45%) of 20 had a diagnosis of diabetes mellitus. Seventeen devices were noninfected, and 3 were associated with clinical infection. Mean device indwelling time prior to explant was 5.1 ± 5.1 years. All analyzed components from 20 devices had detectable microbial biofilms, both in the presence and absence of infection. Scanning electron microscopy corroborated the presence of biofilms across device components. Significant differences between viruses, prokaryotes, and metabolic pathways were identified between individual patients, device manufacturers, and infection status. Mobiluncus curtisii was enriched in manufacturer A device biofilms relative to manufacturer B device biofilms. Bordetella bronchialis, Methylomicrobium alcaliphilum, Pseudoxanthomonas suwonensis, and Porphyrobacter sp. were enriched in manufacturer B devices relative to manufacturer A devices. The most abundant bacterial phyla were the Proteobacteria, Actinobacteria, and Firmicutes. Glycogenesis, the process of glycogen synthesis, was among the predominant metabolic pathways detected across device components. Beta diversity of bacteria, viruses, protozoa, and pathways did not differ among device components. CLINICAL IMPLICATIONS: All components of all penile prostheses removed from infected and noninfected patients have biofilms. The significance of biofilms on noninfected devices remains unknown and merits further investigation. STRENGTHS AND LIMITATIONS: Strengths include the multipronged approach to characterize biofilms and being the first study to include all components of penile prostheses in tandem. Limitations include the relatively few number of infected devices in the series, a relatively small subset of devices included in shotgun metagenomics analysis, and the lack of anaerobic and other expanded conditions for culture. CONCLUSION: Penile prosthesis biofilms are apparent in the presence and absence of infection, and the composition of biofilms was driven primarily by device manufacturer, individual variability, and infection, while being less impacted by device component.

The Role of Postoperative Imaging after Ventral Onlay Buccal Mucosal Graft Bulbar Urethroplasty.

PURPOSE: Our primary objective was to determine the incidence of extravasation on imaging at the time of catheter removal after ventral onlay buccal mucosal graft urethroplasty. MATERIALS AND METHODS: This is a single center retrospective cohort study of patients who underwent ventral onlay buccal mucosal graft bulbar urethroplasty from 2007 to 2017. Patients with imaging at the time of catheter removal were included. Urethroplasty success was defined as the ability to pass a 17Fr cystoscope at the time of followup cystoscopy. RESULTS: A total of 229 patients met the inclusion criteria, including 110 with a ventral onlay buccal mucosal graft and 119 with an augmented anastomotic urethroplasty with a mean stricture length of 4.4 cm. Imaging consisted of a voiding cystourethrogram in 210 and retrograde urethrogram in 19 patients at a median of 21.7 days after surgery. The incidence of extravasation was 3.1% (7/229). Of patients who had a documented followup cystoscopy (60%, 137/229), those with extravasation on imaging had a worse urethroplasty success rate (60%, 3/5) compared to those who did not (94%, 117/130) (p=0.047). On multivariate analysis those who had 5 or more endoscopic interventions were 9.6 times more likely to demonstrate extravasation (OR 9.6, p=0.0080). CONCLUSIONS: The incidence of radiological extravasation after ventral onlay using a single buccal mucosal graft, with or without augmented anastomotic urethroplasty, is 3.1%. Given this low rate it is reasonable to omit routine imaging at the time of Foley removal in this population. It appears that extravasation may be associated with a worse cystoscopic patency rate but does not lead to more complications.

Posterior Urethral Reconstruction at the Time of Rectourethral Fistula Repair: Technique and Outcomes.

OBJECTIVE: To assess the impact of posterior urethral stenosis or defect on outcomes following rectourethral fistula (RUF) repair, we present a cohort of 23 men who underwent posterior urethroplasty concurrent with RUF repair. METHODS: We identified 130 men who underwent RUF repair at our institution between 2003 and 2021. Of these, 23 (18%) underwent simultaneous posterior urethroplasty. Fifteen men received prior radiation for prostate cancer. Of the 8 men who were not radiated, 4 had a history of radical prostatectomy, 2 pelvic trauma, and 3 inflammatory bowel disease. All 23 men underwent fecal diversion prior to surgery (median, 6 months preoperatively), and 20 men suprapubic catheter placement (median, 5.5 months preoperatively). RESULTS: RUF repair was performed via perineal approach in 22 cases (96%) and prone Kraske position in 1 (4%). Intraoperatively, 20 men (87%) had urethral stenosis, and 3 (13%) had significant urethral defects due to cavitation and tissue loss. There was stenosis/stricture involving the prostatomembranous urethra in 18 cases (78%) and vesicourethral anastomosis in 5 (22%). Urethroplasty was performed with anastomotic repair in 18 patients (78%) and using a buccal mucosal graft in 5 (22%). Gracilis flap interposition was performed in 21 cases (91%). At a median follow-up of 55.7 months (interquartile range (IQR), 23-82 months), 20 men (87%) had successful RUF closure, with 3 patients experiencing RUF recurrence requiring further surgery. Fourteen men (61%) reported postoperative urinary incontinence, with 7 (30%) ultimately undergoing artificial urinary sphincter placement. There were no isolated stricture recurrences requiring instrumentation. CONCLUSION: Posterior urethral stenosis associated with RUF complicates an already challenging problem. However, most of these patients can be successfully treated concurrent with RUF repair. This series demonstrates that patients with RUF should not be ruled out for restorative reconstructive surgery based on the presence of posterior urethral stenosis or defect.

Decisional regret and impacts on quality of life following genitourinary reconstruction for neurogenic bladder: A comparison between acquired and congenital spinal cord injury.

INTRODUCTION: Patient expectations and baseline health are important drivers of outcomes following major genitourinary reconstructive surgery for neurogenic bladder (NGB). Differences in expectations and quality of life (QoL) improvements among different populations with NGB remain insufficiently explored in the literature. OBJECTIVE: To compare decisional regret (DR) and urinary-related QoL (UrQoL) in patients undergoing urinary diversion for NGB arising from spinal cord injury of acquired (A-SCI) and congenital (C-SCI) etiologies. We hypothesize that patients with A-SCI have higher expectations of improvement in QoL following surgery when compared with C-SCI, which may lead to higher DR and decreased UrQoL, postoperatively. DESIGN: In this cross-sectional survey study, we compared A-SCI to C-SCI in terms of DR, UrQoL, and postoperative changes in self-reported physical health, mental health, and pain using validated patient-reported outcome measures. SETTING: Participants were enrolled from a quaternary care institution via mail and MyChart. PARTICIPANTS: The A-SCI group consistied of 17 patients with traumatic spinal cord injury the C-SCI group was composed of 20 patients with spina bifida. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Decisional Regret Scale, Short form- Qualiveen (SF-Qualiveen), and Patient-reported outcomes measurement Information system-10 (PROMIS-10) Global Health surveys. RESULTS: The A-SCI group displayed poorer preoperative physical health than the C-SCI cohort, but absolute postoperative changes in this score, along with mental health score and pain level, were not significant after adjusting for baseline scores and follow-up time. SF-Qualiveen scores revealed significantly worse impact of NGB in UrQoL for A-SCI than for C-SCI when adjusted for other factors. No differences in DR were seen between the groups. CONCLUSIONS: Patients with A-SCI demonstrate lower self-reported baseline physical health compared with patients with C-SCI, which may have implications in setting patient expectations when undergoing urinary diversion. In this small cohort, we found a milder self-reported postoperative impact of NGB in UrQoL in patients with C-SCI.

Erosion of inflatable penile prosthesis reservoir into neobladder.

INTRODUCTION: Erosion of the reservoir into surrounding tissues is a rare complication after inflatable penile prosthesis (IPP) implantation. AIM: To present a new case and a review of the literature including discussion of pathogenesis, risk factors, and management options. METHODS: We present the case of a 75-year-old male who underwent placement of an IPP for postoperative erectile dysfunction with a history of bladder cancer requiring radical cystoprostatectomy and Studer neobladder. Six years after IPP placement, he presented with recurrent febrile urinary tract infection that seemed to be precipitated by cycling of his penile prosthesis. Cystoscopy and cross-sectional computed tomography imaging demonstrated erosion of the inflatable penile prosthesis reservoir into the neobladder. RESULTS: Patient underwent open removal of the IPP reservoir and cystorrhaphy with a plan for future prefascial reimplantation of an IPP reservoir. CONCLUSIONS: In patients with a history of abdomino-pelvic surgery or radiation therapy, the retroperitoneal space may be extremely fibrotic and the transversalis fascia may have thickened. Potential intraoperative complications as well as reservoir erosion may be avoided by using a two-piece device or ectopic reservoir placement. Management options for reservoir erosion include explantation of the entire device as well as reservoir removal with salvage of remaining components.

Bilateral Cavernosal Artery Ligation to Treat Ischemic Priapism Following Inflatable Penile Prosthesis Implantation.

OBJECTIVE: To describe the first known case of recurrent acute priapism after penile prosthesis implantation. MATERIALS AND METHODS: A 60-year-old gentleman with a history of recurrent ischemic priapism without hemoglobinopathy presented with refractory erectile dysfunction and underwent uncomplicated penile prosthesis placement. His course was complicated by early acute ischemic priapism confirmed via ultrasound. Due to his pain, attempts to relieve the priapism using ultrasound-guided phenylephrine injections were attempted but were unsuccessful. RESULTS: He subsequently underwent exploration with confirmation of distal ischemic priapism followed by brisk bright red blood from the proximal corpora upon device externalization. A perineal exploration was performed and the bilateral cavernosal arteries were suture ligated with immediate relief. The device was reimplanted and the patient recovered uneventfully. CONCLUSION: We report the first known case of ischemic priapism following inflatable penile prosthesis implantation. The details of this case challenge the dogma that priapism is a binary event and instead supports an imbalance between unopposed cavernosal artery inflow possibly due to vascular calcifications and compromised venous outflow due to the presence of the device. Prosthetic urologists should be aware of this rare phenomenon and consider all available approaches on an individualized case-by-case basis.

Management and Outcomes of Ileal Pouch-Urethral Fistulas.

OBJECTIVE: To describe a single-center experience with the management of ileal pouch-urethral fistulas (IPUF) following restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). METHODS: We retrospectively identified patients with documented IPUF managed at our institution from a urethral fistula cohort and analyzed their cases. RESULTS: Thirteen patients who underwent surgeries for IPUF management from 2005-2022 were identified. Median age at IPAA was 29 years (range 11-53). Indications for IPAA included familial adenomatous polyposis (n=3) and ulcerative colitis (n=10). Median time from IPAA to fistula diagnosis was 15 years (range 0.5-38.5). Eleven patients were initially diverted with either loop (n=8) or end ileostomy (n=3). Overall, two patients had resolution of IPUF symptoms with a loop ileostomy alone and eight eventually underwent pouch excision with end ileostomy, one of which subsequently underwent redo IPAA. Seven patients were managed with primary closure of the urethral defect at the time of pouch excision, five of which also underwent gracilis muscle interposition. With a median follow-up of 4 years (range 0.3-13 years), all patients had resolution of their fistulae without any recurrences. CONCLUSION: IPUFs are a rare complication after IPAA. In this cohort, all patients had their urinary tract preserved, but most ultimately had permanent fecal diversion. These results can help guide management of this complex issue.

Cancer risk in bladder diverticula: a large institutional analysis of risk and management.

PURPOSE: Bladder diverticula (BD) are usually asymptomatic, but may increase the risk of infections, stones, or malignancy, likely due to urinary stasis within the BD. We aim to characterize the risk of bladder cancer (BC) within diverticula. METHODS: Retrospective review was conducted of patients diagnosed with BD between 1994 and 2021 at a single institution. Cancer risk was characterized using descriptive statistics and multivariable logistic regression as appropriate. RESULTS: We identified 764 patients with mean age 68 years, the majority of whom were male (87%) and Caucasian (86%). Of this total, 13.3% (102/764) had a diagnosis of BC and 35.3% of this subset (36/102) had definitive cancer within the BD. Diverticulectomy or partial cystectomy was performed in 13.6% (104/764), 76% of whom were preoperatively presumed to have benign disease. Surgical patients were younger and had larger BD. Of the 79 patients who underwent diverticulectomy without preoperative suspicion for cancer, 5 were incidentally diagnosed with BC on final pathology. On multivariable logistic regression, male gender [odds ratio (OR) = 2.6, p = 0.03] and increasing age (OR = 1.02, p = 0.03) were independent risk factors for BC diagnosis. Indwelling catheter, recurrent urinary tract infections (UTIs), and bladder stones did not affect the risk of BC. CONCLUSIONS: The majority of patients with BD are not managed with surgery. BC is identified in a small but considerable proportion of patients with BD, with an even lower rate of incidentally diagnosed cancer among those undergoing BD surgery. Male gender and increasing age increased the risk of BC diagnosis.

Outcomes of Inflatable Penile Prosthesis following Radical Cystectomy: A Matched Cohort Analysis.

OBJECTIVE: To evaluate outcomes of inflatable-penile-prosthesis (IPP) implantation after radical-cystectomy compared to other etiologies of erectile dysfunction. MATERIALS AND METHODS: All IPPs within the past 20 years in a large regional health system were reviewed, and erectile dysfunction (ED) etiology was determined as radical-cystectomy, radical-prostatectomy, or organic/other ED. Cohorts were generated by 1:3 propensity score match using age, body mass index, and diabetes status. Baseline demographics and relevant comorbidities were evaluated. Clavien-Dindo complications, grade, and reoperation were assessed. Multivariable logarithmic regression was used to identify the predictors of 90-day complications following IPP implantation. Log-rank analysis was used to assess the time-to-reoperation after IPP implantation in patients with a history of cystectomy compared with noncystectomy etiologies. RESULTS: Of 2600 patients, 231 subjects were included in the study. Comparing patients undergoing IPP for cystectomy vs pooled noncystectomy indications, those who underwent radical-cystectomy had a higher overall complication rate (24% vs 9%, p = 0.02). Clavien-Dindo complication grades did not differ across groups. Reoperation was significantly more common following cystectomy (cystectomy: 21% vs noncystectomy: 7%, p = 0.01), however time to reoperation did not differ significantly by indication (cystectomy: 8 years vs noncystectomy: 10 years,p = 0.09). Among cystectomy patients, 85% of reoperations were due to mechanical failure. CONCLUSION: Compared to other erectile dysfunction etiologies, patients undergoing IPP with a history of cystectomy have an increased risk of complications within 90-days of implantation and need for surgical device revision, but no greater risk for high-grade complications. Overall IPP remains a valid treatment option after cystectomy.

Biofilms on Indwelling Artificial Urinary Sphincter Devices Harbor Complex Microbe-Metabolite Interaction Networks and Reconstitute Differentially In Vitro by Material Type.

The artificial urinary sphincter (AUS) is an effective treatment option for incontinence due to intrinsic sphincteric deficiency in the context of neurogenic lower urinary tract dysfunction, or stress urinary incontinence following radical prostatectomy. A subset of AUS devices develops infection and requires explant. We sought to characterize biofilm composition of the AUS device to inform prevention and treatment strategies. Indwelling AUS devices were swabbed for biofilm at surgical removal or revision. Samples and controls were subjected to next-generation sequencing and metabolomics. Biofilm formation of microbial strains isolated from AUS devices was reconstituted in a bioreactor mimicking subcutaneous tissue with a medical device present. Mean patient age was 73 (SD 10.2). All eighteen artificial urinary sphincter devices harbored microbial biofilms. Central genera in the overall microbe−metabolite interaction network were Staphylococcus (2620 metabolites), Escherichia/Shigella (2101), and Methylobacterium-Methylorubrum (674). An rpoB mutation associated with rifampin resistance was detected in 8 of 15 (53%) biofilms. Staphylococcus warneri formed greater biofilm on polyurethane than on any other material type (p < 0.01). The results of this investigation, wherein we comprehensively characterized the composition of AUS device biofilms, provide the framework for future identification and rational development of inhibitors and preventive strategies against device-associated infection.

Microbe-metabolite interaction networks, antibiotic resistance, and in vitro reconstitution of the penile prosthesis biofilm support a paradigm shift from infection to colonization.

To understand differences between asymptomatic colonized and infected states of indwelling medical devices, we sought to determine penile prosthesis biofilm composition, microbe-metabolite interaction networks, and association with clinical factors. Patients scheduled for penile prosthesis removal/revision were included. Samples from swabbed devices and controls underwent next-generation sequencing, metabolomics, and culture-based assessments. Biofilm formation from device isolates was reconstituted in a continuous-flow stir tank bioreactor. 93% of 27 analyzed devices harbored demonstrable biofilm. Seven genera including Faecalibaculum and Jeotgalicoccus were more abundant in infected than uninfected device biofilms (p < 0.001). Smokers and those with diabetes mellitus or cardiac disease had lower total normalized microbial counts than those without the conditions (p < 0.001). We identified microbe-metabolite interaction networks enriched in devices explanted for infection and pain. Biofilm formation was recapitulated on medical device materials including silicone, PTFE, polyurethane, and titanium in vitro to facilitate further mechanistic studies. Nearly all penile prosthesis devices harbor biofilms. Staphylococcus and Escherichia, the most common causative organisms of prosthesis infection, had similar abundance irrespective of infection status. A series of other uncommon genera and metabolites were differentially abundant, suggesting a complex microbe-metabolite pattern-rather than a single organism-is responsible for the transition from asymptomatic to infected or painful states.

Therapeutic durability of the male transobturator sling: midterm patient reported outcomes.

PURPOSE: The male transobturator AdVance™ sling is a viable option for mild to moderate post-prostatectomy incontinence. As this treatment is relatively new, our study provides an analysis of efficacy through patient reported outcomes and pad use. MATERIALS AND METHODS: A telephone survey and chart review were conducted on all patients receiving a sling before 2010 by either of 2 surgeons at a large academic institution. The survey included the Patient Global Impression of Improvement and Severity instruments, pad use characteristics before and after sling surgery, and items assessing durability of efficacy. Patient determined (subjective) success was very much or much better on the Patient Global Impression of Improvement without subsequent incontinence therapy. Quantitative success was defined as a decrease to 2 or fewer pads per day. We assessed therapeutic durability in a subanalysis of patients interviewed twice, first in a prior study. RESULTS: From initial office followup to 2 years, quantitative success decreased from 87.3% to 62.5% and pad use doubled from a mean±SD of 0.8±1.7 to 1.7±2.5 pads per day. Patient determined success was 53.6% at 2 years. A subgroup of 25 patients interviewed at 7 and 29 months after sling surgery had quantitative success significantly decrease by 20% (p=0.03), subjective success decrease by 4% (p=0.56) and pad use significantly increase (p=0.01) from 1.4±2.2 to 2.3±3.2 pads per day. CONCLUSIONS: Most patients receiving the AdVance sling did see improvement in post-prostatectomy incontinence and a decrease in pad use, but in 20% of patients this benefit decreased with time. Nevertheless, patients remained satisfied and perceived the treatment as successful.

Evaluation and treatment of adult concealed penis.

Concealed penis is a rare congenital disorder most commonly seen in children and the condition and surgical management have been well described. In contrast, there is a paucity of information with regards to adult concealed penis. Adult concealed penis may be due to trapping from skin contraction related to lichen sclerosis, cicatricial scars following surgical procedures, or prepubic adipose tissue causing poor phallic exposure. One of the greatest risk factors for concealed penis is obesity, and as this becomes a national pandemic, the incidence of adult concealed penis may increase. Therefore, a greater number of urologists may be faced with treating this difficult condition. This article reviews the etiology of adult concealed penis and describes the patient evaluation and various surgical approaches.

Congenital penile curvature: update and management.

Congenital penile curvature results from disproportionate development of the tunica albuginea of the corporal bodies and is not associated with urethral malformation. Patients usually present after reaching puberty as the curvature becomes more apparent with erections, and severe curvature can make intercourse difficult or impossible, at which point surgical repair is recommended. Excellent outcomes can be expected with surgical intervention. The three most commonly used repair techniques are the original Nesbit procedure, modified Nesbit procedure, and plication. Nesbit and modified Nesbit techniques require that an incision is made in the tunica albuginea while plication techniques utilize plicating sutures without an incision. While Nesbit and modified Nesbit techniques are more complex operations, these generally result in less recurrences and more satisfactory outcomes as opposed to the quicker and simpler plication technique.

Management of Urosymphyseal Fistula and Pelvic Osteomyelitis: A Comprehensive Institutional Experience and Improvements in Pain Control.

BACKGROUND: Urosymphyseal fistula (USF) is an uncommon but painful and devastating condition typically occurring after radiotherapy for pelvic malignancy, with a delayed diagnosis and a risk of opioid dependence. OBJECTIVE: To characterize our institutional experience and determine the impact of intervention for USF on pain control and opioid use. DESIGN, SETTING, AND PARTICIPANTS: We evaluated data for 33 adult patients diagnosed with USF and managed at a quaternary institution between 2009 and 2021. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We assessed chronic opioid use, pain scores, prior therapy for pelvic malignancy, prior endoscopic procedures, microbiology and histology congruence, and postoperative complications. For comparative analyses we used a χ2 test or Fisher's exact test for categorical variables and a Wilcoxon signed-rank test for continuous variables. RESULTS AND LIMITATIONS: Nearly 94% of the patients had received prior pelvic radiotherapy and >80% occurred in 2016-2021 but were not diagnosed until a median of 10 mo (interquartile range [IQR] 3.5-19.5) following endoscopic procedure(s). Osteomyelitis was suspected in 78.8% of imaging reports and nearly 70% had a positive preoperative urine culture. Over 90% of patients underwent cystectomy, pubic bone debridement or resection, and a soft-tissue pedicle flap. Preoperative urine cultures were concordant with 60% of intraoperative tissue/bone cultures. Histologic osteomyelitis was identified in 85% and concordant with 80% of preoperative imaging. Clavien-Dindo grade ≥3 complications occurred in 15.6%. The median pain score decreased from 4 (IQR 0-8) preoperatively to 0 (IQR 0) postoperatively (p < 0.001). Chronic opioid use decreased from 39.4% to 21.2% (p = 0.02). CONCLUSIONS: Pelvic osteomyelitis may complicate USF and commonly manifests with severe, persistent pain. USF incidence may be increasing or at least increasingly recognized, but diagnosis is delayed. Definitive management results in significant improvements in pain perception and a decrease in chronic opioid use. PATIENT SUMMARY: We examined features of urinary fistulas, which are abnormal openings or connections between part of the urinary tract and another structure. Patients with a urinary fistula involving the pelvic bones can present with severe pain, but diagnosis of the condition is often delayed. Removal of some pelvic bone with bladder removal or repair can result in a decrease in long-term pain and in the use of opioid drugs for pain relief.

Extensive dystrophic calcification of eroded artificial urinary sphincter cuff-a rare cause of urethral obstruction: a case report.

Background: Despite a high technical success rate and satisfaction, complications of an artificial urinary sphincter (AUS) can occasionally occur and vary in severity from transient urinary retention to unrecognized urethral injury or urethral erosion. Infection usually occurs when urine comes into contact with the device and necessitates explant of the cuff followed by delayed device replacement. In rare cases, however, the device can remain in contact with urine for long periods of time without the sequelae normally associated with acute infection. Case Description: Here we present a case report of two patients with intraurethral migration of AUS cuffs associated with calcification resulting in urethral obstruction precluding catheterization. With extensive calcification around the cuff and longstanding complete erosion into the urethra, the urologist can expect obliteration of normal tissue planes and intense fibrosis during cuff explantation. Following excision of the cuff and stones, assessment of the urethral lumen should be performed to determine whether repair of the urethra is required. After surgery, urinary diversion with a urethral catheter is important to allow for urethral healing. Prior to considering AUS replacement, cystoscopic assessment of the urethra is critical to assess for stricture or other abnormality. Conclusions: Extensive calcification following AUS erosion into the urethra requires the expertise of a urologist with experience in urethral surgery in order to optimize outcomes. Urologists should be aware of this uncommon, but dramatic presentation of urethral obstruction due to a chronically eroded AUS cuff.

Management of prostatosymphyseal fistula following photoselective vaporization of the prostate: Case series and systematic review of the literature.

Background: This study is aimed to describe our institutional experience and review the literature to date on prostatosymphyseal fistula (PSF), or puboprostatic fistula, following bladder outlet procedures such as transurethral resection of the prostate (TURP) or laser photoselective vaporization of the prostate (PVP). Materials and methods: We retrospectively queried our institutional experience for management of PSF following PVP performed for symptomatic benign prostatic hyperplasia. We also performed a systematic literature review for PSF following PVP or TURP. Finally, we describe our surgical approach to the management of this challenging condition. Results: We identified 7 cases of PSF following PVP from our institution, as well as an additional 7 cases following PVP and 9 cases following TURP from literature review. The diagnosis of PSF was made between 0.5 and 24 months following PVP, and the most specific symptoms were pubic pain and difficulty ambulating. Most patients requiring several evaluations before the diagnosis was made using appropriate imaging studies. Seventy percent of patients required surgical intervention including fistula repair or prostatectomy. Our surgical approach has evolved, and we now routinely perform robotic fistula repair with Y-V plasty and interposition flap with excellent results. Conclusions: Puboprostatic fistula is a rare and poorly described complication of PVP or TURP. To the best of our knowledge, this case series of PSF following PVP represents the largest series to date and doubles the number of reported cases in the literature. Robotic fistula repair with interposition of either peritoneal or perivesical fat flaps appears to be a viable management strategy.

Screening and diagnosis of prostate cancer in patients with ileal pouch-anal anastomosis: consensus from an expert panel.

Screening for prostate cancer after restorative proctocolectomy with ileal pouch-anal anastomosis can be challenging. Diagnostic biopsy for an elevated level of prostate-specific antigen may present difficulties as well. No guidelines have been issued regarding the value and accuracy of digital examination and the best route to obtain prostate biopsy specimens. A screening and diagnostic algorithm for prostate cancer was developed by an expert consensus panel.

The Cleveland Clinic experience with adult hypospadias patients undergoing repair: their presentation and a new classification system.

OBJECTIVE: • To characterize and categorize adults with hypospadias who presented to our clinic with urethral stricture and fistula to better clarify the presentation, history and intraoperative findings in this heterogeneous group and to better describe the natural history of this anomaly in adulthood. PATIENT AND METHODS: • A retrospective chart review was performed on adults with hypospadias who underwent urethroplasty for urethral stricture, urethrocutaneous fistula, and/or hypospadias repair at Cleveland Clinic between 1993 and 2009. All procedures were performed by a single staff surgeon (K.W.A.). • The charts were reviewed for site of hypospadias, presenting complaint, overall symptoms, history of repair and type of surgery performed. RESULTS: • Fifty-five adult patients were identified. Median age was 37 years (range: 18-72). About half of the patients had distal (glanular/subcoronal or pendulous) hypospadias (56.4%) and the others had more proximal (bulbar) hypospadias (43.6%). • Voiding symptoms (such as dysuria, weak stream, spraying, urgency, frequency) were the most common presenting complaint (50.9%) and overall symptom (81.8%). About half of patients underwent a two-stage urethroplasty (52.7%). • Based on their history of repair, patients were divided into three categories: I, patients who have undergone continuous multiple surgeries for repair with significant scarring and tissue loss; II, delayed complications after an initially successful childhood repair; and III, no previous repair. Most patients were category I (58.2%); however, seven patients (12.7%) were category III. Balanitis xerotica obliterans (BXO) was more common in this subgroup compared with other categories (42.9% vs 8.3%, respectively, P= 0.037). In two of the three patients in category III with BXO, the stricture length was longer than 7 cm. CONCLUSIONS: • Adults with hypospadias represent a heterogeneous group. More than half of adults with complications related to hypospadias have had multiple operations (category I) representing one of the most difficult challenges to the reconstructive urologist. • Roughly 30% of patients undergo an initially successful repair in childhood with recurrent problems in adulthood (category II), suggesting that the outcomes of repair may not be as durable as estimated by studies with shorter-term follow-up. • Finally, BXO is over-represented in men with hypospadias who have not previously undergone repair, which contradicts the previous suggestion that the risk of BXO is related to the use of skin grafts/flaps from previous repairs and suggests that there may be an increased risk of severe stricture disease in patients who have never undergone corrective surgery for this anomaly.
