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.

Estimated Glomerular Filtration Rate Using Cystatin C is a More Sensitive Marker for Kidney Dysfunction in Nonweight-bearing Individuals.

PURPOSE: Individuals with neuromuscular disorders and neurogenic lower urinary tract dysfunction are commonly nonweight-bearing with lower lean muscle mass than the general population. We sought to compare estimated glomerular filtration rate equations that include creatinine, cystatin C, or both, in nonweight-bearing individuals and matched ambulatory controls. MATERIALS AND METHODS: Records were reviewed for individuals with serum creatinine (Cr) and cystatin C (Cys) and diagnosis consistent with nonweight-bearing status, and matched ambulatory controls. The 2021 CKD-EPI (Chronic Kidney Disease-Epidemiology Collaboration) race agnostic equations were used to calculate estimated glomerular filtration rate. Renal function was compared by equation in the overall cohorts and in a patient subset with imaging and/or urinalysis evidence of renal dysfunction. RESULTS: Nonweight-bearing (n = 102) and control populations (n = 204) had similar demographics. In the nonweight-bearing population, estimated glomerular filtration rate differed when calculated using CKD-EPICr, CKD-EPICr+Cys, and CKD-EPICys (107, 93, 80 mL/min/1.73 m2, respectively, P < .001). The differences in estimated glomerular filtration rate were greater in the nonweight-bearing relative to the control group regardless of CKD-EPI equation pairs compared (P < .001). In the patient subset with imaging and/or proteinuria evidence of renal dysfunction, the nonweight-bearing population again had different estimated glomerular filtration rate when calculated using CKD-EPICr, CKD-EPICr+Cys, and CKD-EPICys (P < .001). Fifty-eight percent of nonweight-bearing individuals with evidence of renal dysfunction on imaging or urinalysis were reclassified into a lower estimated glomerular filtration rate category when using estimated glomerular filtration rateCys relative to estimated glomerular filtration rateCr. CONCLUSIONS: Estimated glomerular filtration rate equations containing serum creatinine, cystatin C, or both, validated in mostly ambulatory populations, are not equivalently accurate in estimating kidney function in nonweight-bearing individuals. Comparison of these equations against gold standard glomerular filtration rate measurement is needed to determine which most closely approximates true glomerular filtration rate.

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.

Single-Port Endorobotic Rectal Mucosa Harvest For Urethral Reconstruction.

BACKGROUND: Colorectal mucosal grafts for substitution urethroplasty are alternatives for patients when buccal mucosa is not adequate for long urethral strictures. IMPACT OF INNOVATION: This study presents the first cases of single-port endorobotic rectal mucosa harvesting for urethral reconstruction. TECHNOLOGY MATERIALS AND METHODS: The patients are 43- and 57-year-old men with medical histories of lichen sclerosis. The urethrograms demonstrated panurethral strictures requiring long mucosal grafts. The single-port robot was docked under general anesthesia in the modified lithotomy position. The procedure began with a submucosal injection of a lifting agent. After achieving an adequate lift of the mucosa, the dissection was started 2 cm proximal to the sphincter complex with a hook and continued cephalad. The semiflexible robotic platform eased and facilitated the dissection providing the required traction and counter traction. The injecting needle and aspiration device were directed with the help of a silk knot at the tip of the tools to create a handle for robot arms. The procedure was continued with a spatula tip thinner than the hook, which delivers less energy to the dissection field and creates a precise cut. The harvested graft was provided to the urology team after pinning it for measurement. The urologists prepared and completed the reconstruction of the urethra with the autograft. PRELIMINARY RESULTS: The patient had no complications related to his rectal mucosa harvest. CONCLUSIONS: We report the first 2 cases of single-port robotic rectal mucosal harvesting for long panurethral strictures with single-port endorobotic submucosal dissection technique. FUTURE DIRECTIONS: The technique seems promising to facilitate the precise submucosal dissection with meticulous control of traction and delivered energy.

Education and employment as young adults living with spina bifida transition to adulthood in the USA: A study of the National Spina Bifida Patient Registry.

AIM: To describe the education and employment transition experience of young adults with spina bifida (YASB) and investigate factors associated with employment. METHOD: We queried education and employment data from the US National Spina Bifida Patient Registry from 2009 to 2019. We applied generalized estimating equations models to analyze sociodemographic and disease-related factors associated with employment. RESULTS: A total of 1909 participants (850 males, 1059 females) aged 18 to 26 years contributed 4379 annual visits. Nearly 84% had myelomeningocele and, at last visit, the median age was 21 years (mean 21 years 5 months, SD 2 years 10 months). A total of 41.8% had at least some post-high school education, and 23.9% were employed. In a multivariable regression model, employment was significantly associated with education level, lower extremity functional level, bowel continence, insurance, and history of non-shunt surgery. This large, national sample of YASB demonstrated low rates of post-secondary education attainment and employment and several potentially modifiable factors associated with employment. INTERPRETATION: Specific sociodemographic, medical, and functional factors associated with employment are important for clinicians to consider when facilitating transition for YASB into adulthood. Additional research is needed to understand the impact of cognitive functioning and social determinants of health on transition success in YASB. WHAT THIS PAPER ADDS: There were low education attainment and employment rates in a large sample of young adults with spina bifida. Specific sociodemographic, medical, and functional factors are associated with employment. Some employment-associated factors, such as continence and self-management skills, are modifiable.

The Dilemma of Penile Prosthesis Implantation in Sex Offenders.

BACKGROUND: Penile prosthesis surgeons face an ethical dilemma when confronted with a sex offender who seeks surgical management of erectile dysfunction. AIM: To provide practice guidelines to screen and manage patients with a history of sexual violence prior to surgery. METHODS: Three urologists with expertise in penile prosthesis surgery and 1 medical bioethicist were asked to contribute their opinions and provide recommendations to address this controversial topic. OUTCOMES: Expert opinion supported by analysis of available literature and institutional experience. RESULTS: The authors review current United States legislation, published literature on sex offender registration, and institutional data on the prevalence of sex offenders among men seeking penile prosthesis placement. Within a context established by medical bioethical principles, the authors propose a practice guideline for screening sex offenders prior to penile implantation surgery and referral for trained psychological evaluation prior to surgical management. STRENGTHS & LIMITATIONS: Strengths: multidisciplinary approach in data acquisition including bioethical and legal review. LIMITATIONS: Lack of available evidence regarding recidivism risk in sex offenders who undergo penile prosthesis placement. CONCLUSION: Sex offenders exist among the population of patients seeking surgical placement of a penile prosthesis. A standardized practice guideline for management of this population should be employed with the intention to reduce future harm. Zhang JH, DeWitt-Foy M, Jankowski J, et al.

Age-related urologic problems in the complex urologic patient.

PURPOSE: Improved medical care throughout childhood and adolescence has enabled patients with complex urological abnormalities to live longer into adulthood. These patients are now at risk of developing common, age-related, urological conditions. This review aims to review existing data and make recommendations in areas where expert opinion is currently lacking METHODS: This review represents the joint SIU-ICUD (Société Internationale d'Urologie-International Consultation on Urological Disease) consultation on congenital lifelong urology. The results of this analysis were first presented at a joint consultation of the ICUD and SIU at the 2018 SIU annual conference in Seoul, South Korea. RESULTS: BPH may present differently in patients with neurogenic bladder. Thorough assessment of neurological status, bladder and sphincter function is required before offering any bladder outlet surgery. Prostate specific antigen screening should be offered to men aged 50-69 with neurogenic bladders if they have good life expectancy. Multi-parametric MRI and transperineal biopsy would be the investigations of choice if feasible. Surgery for localized disease should only be done by surgeons with the relevant expertise. Bladder cancer in this patient group is more likely to present at a later stage and have a worse prognosis. Parenthood is achievable for most, but often requires assistance with conception. Pregnant women who have had previous urogenital reconstructive surgery should be managed in appropriate obstetric units with the involvement of a reconstructive urologist. CONCLUSIONS: Most evidence regarding complex urogenital abnormalities comes from the pediatric population. Evidence regarding common, age-related urological issues is generally from the 'normal' adult population. As patients with complex congenital urological conditions live longer, more data will become available to assess the long-term benefits of intervention.

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.

Urologic provider experiences in transitioning spina bifida patients from pediatric to adult care.

PURPOSE: The lack of precedent in transitioning from pediatric to adult care poses a challenge to providers for patients with spina bifida (SB). The purpose of this study was to summarize perceptions about best practices for the care of adult spina bifida patients. MATERIALS AND METHODS: A national survey was electronically distributed to 174 urologists who are current members of the Spina Bifida Association Network and AUA Working Group on Urologic Congenitalism. De-identified voluntary responses were assessed for implementation of and barriers to interdisciplinary adult SB clinics, continuity of care, and practices for transitioning from pediatric to adult care. RESULTS: The response rate was 40% with urologists practicing pediatrics, genitourinary reconstruction, female pelvic medicine and general urology. Patients undergoing transition or who have transitioned were seen in a multidisciplinary clinic (14%), regular adult clinic (34%), combined adult-pediatric multidisciplinary care (20%), or pediatric multidisciplinary clinic (28%). A majority believed transitioning to adult care should occur at 18 (24%) or 21 years (22%). In the absence of acute changes, providers followed adult SB patients annually with upper tract imaging (typically renal ultrasound) and serum creatinine. Acute urologic changes were preferentially managed with urodynamic testing and cystoscopy. Providers identified a need for multidisciplinary care in adult life, with neurosurgery/neurology (87%), social work (84%), and orthopedics (73%). CONCLUSIONS: Potential solutions to improve the urologic care of this population suggest additional national provider resources, standardized guidelines, multidisciplinary collaboration, access to care, and an advanced-training pathway to improve care of adult patients with spina bifida.

Trends in Renal Transplantation Rates in Patients with Congenital Urinary Tract Disorders.

PURPOSE: Improved bladder and renal management benefit patients with congenital uropathy and congenital pediatric kidney disease. This may translate to delayed initial renal transplantation in these patients, and improved graft and patient survival. Our primary study purpose was to determine whether patients with congenital uropathy and congenital pediatric kidney disease have demonstrated later time to first transplantation and/or graft survival. MATERIALS AND METHODS: SRTR (Scientific Registry of Transplant Recipients) was analyzed for first renal transplant and survival data in patients with congenital uropathy and congenital pediatric kidney disease from 1996 to 2012. Congenital uropathy included chronic pyelonephritis/reflux, prune belly syndrome and congenital obstructive uropathy. Congenital pediatric kidney disease included polycystic kidney disease, hypoplasia, dysplasia, dysgenesis, agenesis and familial nephropathy. RESULTS: A total of 7,088 patients with congenital uropathy and 24,315 with congenital pediatric kidney disease received a first renal transplant from 1996 to 2012. A significant shift was seen in both groups toward older age at initial renal transplantation in those 18 through 64 years old. In the congenital uropathy group this effect was most facilitated by decreased renal transplantion in patients between 18 and 35 years old (38% in 1996 vs 26% in 2012). The congenital pediatric kidney disease group showed a substantial decrease in patients who were 35 to 49 years old (from 39% to 29%). At 10-year followup the congenital uropathy group showed better graft and patient survival than the congenital pediatric kidney disease group. However, aged matched comparison revealed comparable survival rates in the 2 groups. CONCLUSIONS: Analysis of trends in the last 14 years demonstrated that patients with both lower and upper tract congenital anomalies experienced delayed time to the first renal transplant. Furthermore, patients had similar age matched graft and patient survival whether the primary source of renal demise was the congenital lower or upper tract. These findings may indicate that improved urological and nephrological care are promoting renal preservation in both groups.

Transitioning young adults with spina bifida: Challenges and paths to success.

INTRODUCTION AND BACKGROUND: Recent medical advances, including closure of myelomeningocele defects, shunting of hydrocephalus, and focusing on renal preservation have led to many individuals with spina bifida (SB) living into adulthood. This has led to more individuals with SB transitioning their care from pediatric-based to adult-based care models. OBJECTIVE: We seek to explore the process of transition, with a focus on difficulties in transitioning individuals with SB. Additionally, we explore new problems that arise during the period of transition related to sexual function and dysfunction. We also discuss some of the difficulties managing neurogenic bladder and the sequalae of their prior urologic surgeries. STUDY DESIGN: Each of the authors was asked to provide a summary, based on current literature, to highlight the challenges faced in their area of expertise. CONCLUSIONS: Transitioning care for individuals with SB is especially challenging due to associated neurocognitive deficits and neuropsychological functioning issues. Sexual function is an important component of transition that must be addressed in young adults with SB. Management of neurogenic bladder in adults with SB can be challenging due to the heterogeneity of the population and the sequelae of their prior urologic surgeries. The aim is to ensure that all individuals with SB receive appropriate, evidence-based care throughout their lifetime.

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.

Impact of parturition on chemokine homing factor expression in the vaginal distention model of stress urinary incontinence.

PURPOSE: Human childbirth simulated by vaginal distention is known to increase the expression of chemokines and receptors involved in stem cell homing and tissue repair. We hypothesized that pregnancy and parturition in rats contributes to the expression of chemokines and receptors after vaginal distention. MATERIALS AND METHODS: We used 72 age matched female Lewis rats, including virgin rats with and without vaginal distention, and delivered rats with and without vaginal distention. Each rat was sacrificed immediately, or 3 or 7 days after vaginal distention and/or parturition, and the urethra was harvested. Relative expression of chemokines and receptors was determined by real-time polymerase chain reaction. Mixed models were used with the Bonferroni correction for multiple comparisons. RESULTS: Vaginal distention up-regulated urethral expression of CCL7 immediately after injury in virgin and postpartum rats. Hypoxia inducible factor-1α and vascular endothelial growth factor were up-regulated only in virgin rats immediately after vaginal distention. CD191 expression was immediately up-regulated in postpartum rats without vaginal distention compared to virgin rats without vaginal distention. CD195 was up-regulated in virgin rats 3 days after vaginal distention compared to virgin rats without vaginal distention. CD193 and CXCR4 showed delayed up-regulation in virgin rats 7 days after vaginal distention. CXCL12 was up-regulated in virgin rats 3 days after vaginal distention compared to immediately after vaginal distention. Interleukin-8 and CD192 showed no differential expression. CONCLUSIONS: Vaginal distention results in up-regulation of the chemokines and receptors expressed during tissue injury, which may facilitate the spontaneous functional recovery previously noted. Pregnancy and delivery up-regulated CD191 and attenuated the expression of hypoxia inducible factor-1α and vascular endothelial growth factor in the setting of vaginal distention, likely by decreasing hypoxia.

Development of a Clinical-scholar Index Score for Measuring Academic Contributions in Urology.

OBJECTIVE: To develop an academic index that would permit annual measurement of faculty non-clinical activities. METHODS: Academic activities were extracted from curriculum vitae (CV) and sorted into pre-determined categories. Categories were weighted based on discussion with department leadership. Weights were scaled 0-1 with 0 being defined as an activity that was non-essential to the mission, brought little to no external recognition or was beneath the appropriate milestone for the individual (middle author publications for a senior career staff member). 1 was defined as an activity that was essential to the department's mission, a significant time commitment for the individual, and provided external recognition. Annual scholarly index scores were determined for all participants based on their weighted contributions for the year. RESULTS: Early career staff primarily make contributions through peer-reviewed publications and presentation. Velocity of scholarly contributions was greatest during the Mid-career (MC) stage. Senior career (SC) urologists had the most diverse array of contributions of any group. Like many of the MC faculty, SC faculty demonstrated a decrease in nonclinical productivity beginning in 2018 following a shift in organizational priorities to increased clinical productivity. CONCLUSIONS: Nonclinical contributions of academic urologists can be quantified and tracked annually using this academic index. By doing so, leadership can more easily identify ways to support career development, which is especially important in mid-career, where individuals likely have the greatest opportunity for growth or stagnation. Finally, shifts in organization-wide priorities affect academic contributions and can be quantified by the model.

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.

Urinalysis Exhibits Excellent Predictive Capacity for the Absence of Urinary Tract Infection.

OBJECTIVE: To assess predictive value of urinalysis for negative urine culture and absence of urinary tract infection, re-evaluate the microbial growth threshold for positive urine culture result, and describe antimicrobial resistance features. Urine culture is associated with 27% of U.S. hospitalizations, and unnecessary antibiotic prescription is a main antibiotic resistance contributor. METHODS: Urinalyses with urine culture from women ages 18-49 from 2013 to 2020 were studied. Clinically diagnosed urinary tract infection (CUTI) was defined as (1) uropathogen growth, (2) documented diagnosis of urinary tract infection, and (3) antibiotic prescription. Sensitivity, specificity, and diagnostic predictive values were used to assess urinalysis performance in predicting isolation of a uropathogen by culture and in detection of CUTI. RESULTS: Total 12,252 urinalyses were included. Forty-one percent of urinalyses were associated with positive urine culture and 1287 (10.5%) with CUTI. Negative urinalysis exhibited high predictive accuracy for negative urine culture (specificity 90.3%, PPV 87.3%) and absence of CUTI (specificity 92.2%, PPV 97.4%). Twenty-four percent of patients not meeting the CUTI definition were still prescribed antibiotics. Twenty-two percent of cultures associated with CUTI exhibited growth less than 100,000 CFU/mL. Escherichia coli was implemented as causing 70% of CUTIs, and 4.2% of these produced an extended spectrum beta-lactamase. CONCLUSION: Negative urinalysis exhibits high predictive accuracy for absence of CUTI. A reporting threshold of 10,000 CFU/mL is more clinically appropriate than a 100,000 CFU/mL cutpoint. Reflex culture based on urinalysis results could complement clinical judgement and improve laboratory and antibiotic stewardship in premenopausal women.
