Personal genital satisfaction is associated with differences in perception of male and female sexual anatomy and function.

BACKGROUND: Prior studies primarily of men correlated low personal genital satisfaction (PGS) with decreased sexual activity; however, the association between PGS and genital anatomy perceptions is unknown, and there is a paucity of studies examining women. AIM: We assessed the relationship between genital satisfaction, survey respondent sexual activity, and perceptions of anatomy and function. METHODS: A 54-item REDCap survey was distributed to any-gendered volunteers ≥18 years of age through ResearchMatch from January to March 2023. Responses were split into (1) high PGS and (2) low PGS. Analysis was performed using chi-square tests on survey responses and a Mann Whitney U test on median satisfaction level. OUTCOMES: Outcomes were genital anatomy perceptions, sexual activity, and respondents' PGS. RESULTS: Of the 649 respondents who started the survey, 560 (86.3%) completed it. Median PGS was 7 of 10, forming subgroups of high (≥7 of 10) satisfaction (n = 317 of 560 [56.6%]) and low (<7 of 10) satisfaction (n = 243 of 560 [43.4%]). The mean age was 45.8 ± 16.8 years, and demographics were notable for 72.1% women (n = 404 of 560), 83.2% White (n = 466 of 560), 47.9% married (n = 268 of 560), and 75.5% bachelor's degree holders (n = 423 of 560). Comparing high- and low-PGS groups, more low-PGS respondents felt normal flaccid penis length to be <2 inches (11.1% vs 5.1%; P = .008). High-PGS respondents more often responded that it is normal for women to have orgasms over half the time (20.8% vs 13.2%; P = .0002) or to identify as being sexually active (81.1% vs 71.6%; P = .008). Women were more likely than men to report larger normal testicle sizes as 60.1 to 90 mL (24.5% vs 10.3%; P < .0001), whereas more men felt that normal testicle size was 7 to 15 mL (26.3% vs 11.4%; P < .0001). Orgasm length perceptions also differed: more women felt female orgasm length was 2.6 to 5 seconds (36.6% vs 16.7%; P < .0001), and more men believed female orgasms to be longer, at 7.6 to 10 seconds (29.5% vs 17.3%; P = .002), 10.1 to 12.5 seconds (11.5% vs 5.2%; P = .0008), and >12.5 seconds (12.2% vs 5.7%; P = .009). Respondents' views on their genitalia differed by gender, with women more likely to feel that their genitals are normal compared with men (89.4% vs 75.0%; P < .0001). CLINICAL IMPLICATIONS: PGS may be a useful screening tool given its association with sexual activity. STRENGTHS AND LIMITATIONS: Our large-scale survey assesses public perceptions of genital anatomy and function. Limitations include a lack of gender nonbinary perceptions. CONCLUSION: Gender and PGS interact with perceptions of male anatomy and female sexual activity, and the frequency of sexual activity was higher among high-PGS respondents; however, the direction of these interactions remains unclear and requires future causal analysis.

Retrospective Multicenter Observational Study of Immediate Voiding at End of Urinary Sphincter Surgery (REMOVE).

PURPOSE: Patients may remain catheterized after artificial urinary sphincter surgery to prevent urinary retention, despite a lack of evidence to support this practice. Our study aims to evaluate the feasibility of outpatient, catheter-free continence surgery using a multi-institutional database. We hypothesize that between catheterized controls and patients without a catheter, there would be no difference in the rate of urinary retention or postoperative complications. MATERIALS AND METHODS: We conducted a retrospective review of patients undergoing first-time artificial urinary sphincter placement from 2009-2021. Patients were stratified by postoperative catheter status into either no-catheter (leaving the procedure without a catheter) or catheter (postoperative indwelling catheter for ∼24 hours). The primary outcome, urinary retention, was defined as catheterization due to subjective voiding difficulty or documented postvoid residual over 250 mL. RESULTS: Our study identified 302 catheter and 123 no-catheter patients. Twenty (6.6%) catheter and 9 (7.3%) no-catheter patients developed urinary retention (P = .8). On multivariable analysis, controlling for age, cuff size, radiation history and surgeon, there was no statistically significant association between omitting a catheter and urinary retention (OR: 0.45, 95% CI: 0.13-1.58; P = .2). Furthermore, at 30 months follow-up, Kaplan-Meier survival analysis revealed that device survival was 70% (95% CI: 62%-76%) vs 69% (95% CI: 48%-82%) for the catheter and no-catheter group, respectively. CONCLUSIONS: In our multi-institutional cohort, overall retention rates were low (7%) in groups with a catheter and without. Obviating postoperative catheterization facilitates outpatient incontinence surgery without altering reoperation over medium-term follow-up.

Association between Previous Pelvic Radiation and All-Cause and Cause-Specific Failure of Replacement Artificial Urinary Sphincters.

PURPOSE: In order to accurately characterize how a history of radiation therapy affects the lifespan of replacement artificial urinary sphincters (AUSs), all possible sources of device failure must be considered. We assessed the competing risks of device failure based on radiation history in men with replacement AUSs. MATERIALS AND METHODS: We identified men who had a replacement AUS in a single institutional, retrospective database. To assess survival from all-cause device failure based on radiation history and other factors, we conducted Kaplan-Meier, Cox proportional-hazards and competing risks analyses. RESULTS: Among 247 men who had a first replacement AUS, men with a history of radiation had shorter time to all-cause device failure (median 1.4 vs 3.5 years for men with radiation vs without radiation history, p=0.02). On multivariable Cox-proportional hazards analysis, previous radiation was associated with increased risk of all-cause device failure (HR: 2.12, 95% CI: 1.30-3.43, p=0.002). On multivariable cause-specific hazards analysis, prior radiation was associated with a higher risk of erosion/infection (HR: 7.57, 95% CI: 2.27-25.2, p <0.001), but was not associated with risk of urethral atrophy (p=0.5) or mechanical failure (p=0.15). CONCLUSIONS: Among men with a replacement AUS, a history of pelvic radiation was associated with shorter time to device failure of any cause. Radiation was also specifically associated with a sevenfold increase in the risk of erosion or infection of replacement AUS, but not with urethral atrophy or mechanical failure. Patients with a replacement AUS should be appropriately counseled on how radiation history may impact outcomes of future revisions.

Contemporary Trends and End-Results of National Institutes of Health Grant Funding to Departments of Urology in the United States: A 10-year Analysis.

PURPOSE: We explored the patterns and distribution of National Institutes of Health grant funding for urological research in the United States. MATERIALS AND METHODS: The National Institutes of Health RePORTER database was queried for all grants awarded to urology departments between 2010 and 2019. Information regarding the value of the grant, funded institution, successful publication of the research, and the category of urological subspecialty were collected. Data on principal investigators were extracted from publicly available information. RESULTS: There were 509 grants awarded to Urology between 2010 and 2019 for a total value of $640,873,867, and a median per-project value of $675,484 (IQR 344,170-1,369,385). Over the study period, total funding decreased by 15.6% and was lower compared to other surgical subspecialties. Most grants were awarded by the National Cancer Institute and National Institute of Diabetes and Digestive and Kidney Diseases (85%) to Western or North Central institutions (52.5%), and had principal investigators specialized in urologic oncology (56.4%), followed by general urologists (21.5%). Female principal investigators led 21.6% of Urology grants and were more likely PhD basic scientists than males (64.4% vs 38.2%, p=0.001). In total, 10,404 publications linked to the 509 grants were produced, of which 28.5% were published in journals with an impact factor ≥10. CONCLUSIONS: Urology is underrepresented in National Institutes of Health grant funding compared to other surgical fields. During the past decade there was a further decrease in the total budget of National Institutes of Health grants to Urology.

Synchronous genitourinary lichen sclerosus signals a distinct urinary microbiome profile in men with urethral stricture disease.

PURPOSE: Alterations in the urinary microbiome have been associated with urological diseases. The microbiome of patients with urethral stricture disease (USD) remains unknown. Our objective is to examine the microbiome of USD with a focus on inflammatory USD caused by lichen sclerosus (LS). METHODS: We collected mid-stream urine samples from men with LS-USD (cases; n = 22) and non-LS USD (controls; n = 76). DNA extraction, PCR amplification of the V4 hypervariable region of the 16S rRNA gene, and sequencing was done on the samples. Operational taxonomic units (OTUs) were defined using a > 97% sequence similarity threshold. Alpha diversity measurements of diversity, including microbiome richness (number of different OTUs) and evenness (distribution of OTUs) were calculated and compared. Microbiome beta diversity (difference between microbial communities) relationships with cases and controls were also assessed. RESULTS: Fifty specimens (13 cases and 37 controls) produced a 16S rRNA amplicon. Mean sample richness was 25.9 vs. 16.8 (p = 0.076) for LS-USD vs. non-LS USD, respectively. LS-USD had a unique profile of bacteria by taxonomic order including Bacillales, Bacteroidales and Pasteurellales enriched urine. The beta variation of observed bacterial communities was best explained by the richness. CONCLUSIONS: Men with LS-USD may have a unique microbiologic richness, specifically inclusive of Bacillales, Bacteroidales and Pasteurellales enriched urine compared to those with non-LS USD. Further work will be required to elucidate the clinical relevance of these variations in the urinary microbiome.

Outcomes and Risk Factors of Revision and Replacement Artificial Urinary Sphincter Implantation in Radiated and Nonradiated Cases.

PURPOSE: Risk factors for complications after artificial urinary sphincter surgery include a history of pelvic radiation and prior artificial urinary sphincter complication. The survival of a second artificial urinary sphincter in the setting of prior device complication and radiation is not well described. We report the survival of redo artificial urinary sphincter surgery and identify risk factors for repeat complications. MATERIALS AND METHODS: A multi-institutional database was queried for redo artificial urinary sphincter surgeries. The primary outcome was median survival of a second and third artificial urinary sphincter in radiated and nonradiated cases. A Cox proportional hazards survival analysis was performed to identify additional patient and surgery risk factors. RESULTS: Median time to explantation of the initial artificial urinary sphincter in radiated (150) and nonradiated (174) cases was 26.4 and 35.6 months, respectively (p=0.043). For a second device median time to explantation was 30.1 and 38.7 months (p=0.034) and for a third device it was 28.5 and 30.6 months (p=0.020), respectively. The 5-year revision-free survival for patients undergoing a second artificial urinary sphincter surgery with no risk factors, history of radiation, history of urethroplasty, and history of radiation and urethroplasty were 83.1%, 72.6%, 63.9% and 46%, respectively. CONCLUSIONS: Patients without additional risk factors undergoing second and third artificial urinary sphincter surgeries experience revision-free rates similar to those of their initial artificial urinary sphincter devices. Patients who have been treated with pelvic radiation have earlier artificial urinary sphincter complications. When multiple risk factors exist, revision-free rates decrease significantly.

Clinical Outcomes of Periprocedural Antithrombotic Therapy in Ischemic Priapism Management.

BACKGROUND: Priapism is a urologic emergency consisting of a painful erection lasting greater than 4 hours; antithrombotic therapy (ATT) have recently been recommended as an adjunct in the treatment of ischemic priapism. AIM: To determine the short- and long-term outcomes of periprocedural ATT in the management of acute ischemic priapism. METHODS: A retrospective review of patients seen at the University of California, San Francisco, from 2008 to 2019 was carried out to identify those evaluated for acute priapism. Information regarding duration of priapism, etiology, treatment, periprocedural and postprocedural ATT type and dose, and follow-up data was collected. OUTCOMES: ATT use was the exposure of interest; outcome variables included priapism resolution, repeat episodes, long-term complications, and follow-up. RESULTS: 70 patients with at least 1 detailed record of an acute priapism episode between 2008 and 2019 were identified. Of the 70 patients who underwent management for an acute episode of priapism, 59 (84%) received intracavernous injection of phenylephrine with or without corporal aspiration. Of the 4 patients who received ATT at the same time as intracavernous injection, none had additional priapism episodes. In the 55 patients who did not receive immediate ATT, 22 (40%) required at least 1 shunting procedure. The 9 patients who received ATT concurrently with shunting experienced less recurrence than the 13 patients who did not receive ATT (11% vs 69%, respectively P = .012). There were no significant differences in long-term erectile dysfunction (P = .627), fibrosis (P = .118), genitourinary pain (P = .474), and urinary issues (P = .158) between those who received ATT and those who did not. CLINICAL IMPLICATIONS: Our findings suggest that ATT has a role in preventing priapism recurrence; we observed that long-term repeat priapism episodes are less frequent in those who received periprocedural ATT compared with those who did not and that ATT may especially reduce recurrence in cases when shunting was required STRENGTHS & LIMITATIONS: This is the first study looking at the clinical outcomes of periprocedural ATT in the management of ischemic priapism. It is limited by the fact that it is a single-center study, types of ATT were heterogenous, and the exact timing of priapism management could not be measured for everyone. CONCLUSION: In spite of its limitations, these preliminary findings are promising and warrant further exploration of the use of ATT in the management of ischemic priapism.

Characterizing voiding experiences of men choosing seated and standing positions.

AIMS: Voiding positions and preferences in men are not well characterized. In this study, we aim to understand the interplay of voiding characteristics and their impact on voiding position. METHODS: We designed a 27-item survey to assess voiding characteristics and lower urinary tract symptoms (LUTS) severity in men seen in urology and other outpatient clinics. Participants included adult men patients and adult men accompanying patients at our institution's outpatient clinics. Data collected included demographics, International Prostate Symptom Score questionnaire, stream type (single, split, and dribble), voiding behavior, positional stream quality, and voiding bother. RESULTS: We received 195 completed surveys (80% response rate). Of men queried, 18% (35/195) preferred to sit while voiding. Overall, men who sit had a higher proportion of LUTS (66% [23/35] vs. 41% [66/160]; p = .01), more physical limitations affecting voiding choice (20% [7/35] vs. 3% [5/160]; (p = .001), and a lower desire to stand (6% [2/35] vs. 24% [38/160]; p = .02), compared to men who stand. Men who sit while voiding reported nearly double the amount of voiding associated bother (34% [12/35]) compared to men who stand (18% [28/160]; p = .04). Older aged men reported a similar rate of seated urination compared to younger men. The most common reasons to void seated included comfort and avoidance of spraying. CONCLUSIONS: Our findings discourage the use of anecdotal beliefs founded on generalizable characteristics, such as age and stream type, to infer a patient's voiding characteristics. Open dialog with patients regarding voiding preferences may garner important information regarding overall urologic health and better inform urologic care.

Computational Fluid Dynamic Modeling of Urethral Strictures.

PURPOSE: Computational fluid dynamics have paradigm shifting potential in understanding the physiological flow of fluids in the human body. This translational branch of engineering has already made an important clinical impact on the study of cardiovascular disease. We evaluated the feasibility and applicability of computational fluid dynamics to model urine flow. MATERIALS AND METHODS: We prepared a computational fluid dynamics model using an idealized male genitourinary system. We created 16 hypothetical urethral stricture scenarios as a test bed. Standard parameters of urine such as pressure, temperature and viscosity were applied as well as typical assumptions germane to fluid dynamic modeling. We used ABAQUS/CAE 6.14 (Dassault Systèmes®) with a direct unsymmetrical solver with standard (FC3D8) 3D brick 8Node elements for model generation. RESULTS: The average flow rate in urethral stricture disease as measured by our model was 5.97 ml per second (IQR 2.2-10.9). The model predicted a flow rate of 2.88 ml per second for a single 5Fr stricture in the mid bulbar urethra when assuming all other variables constant. The model demonstrated that increasing stricture diameter and bladder pressure strongly impacted urine flow while stricture location and length, and the sequence of multiple strictures had a weaker impact. CONCLUSIONS: We successfully created a computational fluid dynamics model of an idealized male urethra with varied types of urethral strictures. The resultant flow rates were consistent with the literature. The accuracy of modeling increasing bladder pressure should be improved by future iterations. This technology has vast research and clinical potential.

The landscape of urological retractions: the prevalence of reported research misconduct.

OBJECTIVES: To evaluate the landscape of retractions of literature and to determine the prevalence of research misconduct in the field of urology. METHODS: Three databases (PUBMED, Embase, Retraction Watch) were queried for all retracted studies on urological topics in both urological and non-urological journals from April 1999 to March 2018. Two reviewers screened the records and determined the final list of articles to be included in the analysis. RESULTS: A total of 138 articles met the inclusion criteria. Over 80% of retractions occurred after 2009. Retractions originated from 76 different journals (13 urological journals) and 28 countries. The most common reasons for retraction were plagiarism (28%), fake peer review (20%), error (20%), and falsification of data (13%). Misconduct accounted for two-thirds of the retractions (n = 93). A large watermark, indicating retraction of the article, was present in 75% of the manuscripts. Articles were cited a total of 4454 times, 38% of citations happened after retraction. The majority of retracted articles related to urological oncology (70%). The highest number of retractions for an individual author was five. Rates of retraction among popular urological journals since 2010 have increased but remain a small proportion of all publications: BJUI, 0.189%; World Journal of Urology, 0.132%; European Urology, 0.058%; Urology, 0.047%; and Journal of Urology, 0.024%. CONCLUSION: Retractions of urological literature, similarly to retractions of other biomedical literature, have been rising over the last decade. The majority of these retractions stem from research misconduct. Despite retractions, flawed articles continued to be cited.

Exercise Improves Self-Reported Sexual Function Among Physically Active Adults.

BACKGROUND: Sexual dysfunction is common among adults and takes a toll on quality of life for both men and women. AIM: To determine whether higher levels of weekly cardiovascular exercise are protective against self-reported sexual dysfunction among men and women. METHODS: We conducted an international online, cross-sectional survey of physically active men and women between April and December 2016, assessing exercise activity categorized into sextiles of weekly metabolic equivalent-hours. Odds ratios (ORs) of sexual dysfunction for each activity sextile compared with the lowest sextile were calculated using multivariable logistic regression, controlling for age, body mass index, diabetes mellitus, tobacco/alcohol use, sport, and marital status. MAIN OUTCOME MEASURES: Female sexual dysfunction was defined as a score ≤26.55 on the Female Sexual Function Inventory and erectile dysfunction (ED) was defined as a score ≤21 on the Sexual Health Inventory for Men. RESULTS: 3,906 men and 2,264 women (median age 41-45 and 31-35 years, respectively) met the inclusion criteria for the study. Men in sextiles 2-6 had reduced odds of ED compared with the reference sextile in adjusted analysis (Ptrend = .03), with an OR of 0.77 (95% CI = 0.61-0.97) for sextile 4 and 0.78 (95% CI = 0.62-0.99) for sextile 6, both statistically significant. Women in higher sextiles had a reduced adjusted OR of female sexual dysfunction (Ptrend = .02), which was significant in sextile 4 (OR = 0.70; 95% CI = 0.51-0.96). A similar pattern held true for orgasm dissatisfaction (Ptrend < .01) and arousal difficulty (Ptrend < .01) among women, with sextiles 4-6 reaching statistical significance in both. CLINICAL IMPLICATIONS: Men and women at risk for sexual dysfunction regardless of physical activity level may benefit by exercising more rigorously. STRENGTHS & LIMITATIONS: Strengths include using a large international sample of participants with a wide range of physical activity levels. Limitations include the cross-sectional design, and results should be interpreted in context of the study population of physically active adults. CONCLUSION: Higher cardiovascular exercise levels in physically active adults are inversely associated with ED by self-report in men and protective against female sexual dysfunction in women.

Artificial urinary sphincter longevity following transurethral resection of the prostate in the setting of prostate cancer.

PURPOSE: Refractory urinary incontinence after channel transurethral resection of the prostate (cTURP) (TURP in the setting of prostate cancer) is a rare occurrence treated with artificial urinary sphincter (AUS). We sought to characterize those patients receiving AUS after cTURP and understand device longevity. MATERIALS AND METHODS: We identified patients who underwent cTURP and AUS placement in SEER-Medicare from 2002 to 2014. We analyzed factors affecting device longevity using multivariable Cox proportional hazard models. We performed propensity matching to accurately compare patients receiving AUS after cTURP to those receiving AUS after radical prostatectomy (RP). RESULTS: For patients undergoing cTURP, 201 out of 56,957 ultimately underwent AUS placement (< 0.5%). AUS after cTURP incurred a 48.4% rate of reoperation versus 30.9% after RP. Importantly, patients undergoing cTURP were significantly older than those undergoing RP [75 vs. 71 years of age (p < 0.01)]. At 3 years after insertion, 28.2% of patients after RP required reoperation compared to 37.8% of patients post-cTURP (p < 0.01). There were no detectable differences in revision rates for those patients who underwent traditional vs. laser cTURP. Patients with a history of radiation therapy had significantly shorter device survival. Even after propensity matching, patients receiving AUS after cTURP incurred more short-term complications compared to AUS after RP. Differences in device longevity were diminished after propensity match. CONCLUSIONS: In the SEER-Medicare population, AUS after cTURP remains rare. While there is an increased risk of infectious complications, AUS after cTURP fared similarly to AUS after RP in terms of device longevity. A history of radiation therapy leads to worse outcome for all patients.

Perspectives From Authors and Editors in the Biomedical Disciplines on Predatory Journals: Survey Study.

BACKGROUND: Predatory journals fail to fulfill the tenets of biomedical publication: peer review, circulation, and access in perpetuity. Despite increasing attention in the lay and scientific press, no studies have directly assessed the perceptions of the authors or editors involved. OBJECTIVE: Our objective was to understand the motivation of authors in sending their work to potentially predatory journals. Moreover, we aimed to understand the perspective of journal editors at journals cited as potentially predatory. METHODS: Potential online predatory journals were randomly selected among 350 publishers and their 2204 biomedical journals. Author and editor email information was valid for 2227 total potential participants. A survey for authors and editors was created in an iterative fashion and distributed. Surveys assessed attitudes and knowledge about predatory publishing. Narrative comments were invited. RESULTS: A total of 249 complete survey responses were analyzed. A total of 40% of editors (17/43) surveyed were not aware that they were listed as an editor for the particular journal in question. A total of 21.8% of authors (45/206) confirmed a lack of peer review. Whereas 77% (33/43) of all surveyed editors were at least somewhat familiar with predatory journals, only 33.0% of authors (68/206) were somewhat familiar with them (P<.001). Only 26.2% of authors (54/206) were aware of Beall's list of predatory journals versus 49% (21/43) of editors (P<.001). A total of 30.1% of authors (62/206) believed their publication was published in a predatory journal. After defining predatory publishing, 87.9% of authors (181/206) surveyed would not publish in the same journal in the future. CONCLUSIONS: Authors publishing in suspected predatory journals are alarmingly uninformed in terms of predatory journal quality and practices. Editors' increased familiarity with predatory publishing did little to prevent their unwitting listing as editors. Some suspected predatory journals did provide services akin to open access publication. Education, research mentorship, and a realignment of research incentives may decrease the impact of predatory publishing.

Redefining the implications of nasogastric tube placement following radical cystectomy in the alvimopan era.

PURPOSE: Alvimopan has decreased ileus and need for nasogastric tube (NGT) after radical cystectomy (RC). However, the natural history of ileus versus intestinal obstruction in patients receiving alvimopan is not well defined. We sought to examine the implications of NGT placement before and after the introduction of alvimopan for RC patients. METHODS: Retrospective review identified 278 and 293 consecutive patients who underwent RC before and after instituting alvimopan between June 2009 and May 2014. Baseline characteristics and postoperative outcomes were compared by alvimopan status. Multivariate logistic regression was performed to assess the impact of alvimopan on rates of NGT placement and reoperation for bowel complications. RESULTS: The cohorts had similar age, stage, approach, and BMI. Patients receiving alvimopan had decreased ileus (16 vs 32 %, p < 0.01) but similar rates of reoperation for bowel complications (2.8 vs 2.7 %). On multivariate analysis, alvimopan was associated with lower risk of NGT placement (OR 0.30, p < 0.01). For patients requiring NGT placement, there was an increased rate of reoperation among patients receiving alvimopan compared with those who did not (28 vs 11 %, p = 0.03). Patients receiving alvimopan who needed NGT had significantly increased median length of stay (22 vs 7 days), need for TPN (66 vs 5.3 %), and readmission for ileus (10.3 vs 2.3 %) compared with those who did not require NGT. CONCLUSIONS: Alvimopan significantly reduced the incidence of ileus and NGT placement following RC. NGT placement was associated with an increased need for reoperation for bowel complications in the setting of alvimopan.

Medical Neighborhood Model for the Care of Chronic Kidney Disease Patients.

BACKGROUND: The patient-centered medical home is a popular model of care, but the patient-centered medical neighborhood (PCMN) is rarely described. We developed a PCMN in an academic practice to improve care for patients with chronic kidney disease (CKD). The purpose of this study is to identify the prevalence of CKD in this practice and describe baseline characteristics, develop an interdisciplinary team-based approach to care and determine cost associated with CKD patients. METHODS: Patients with CKD stage 3a with comorbidities through stage 5 were identified. Data collected include demographics, comorbidities and whether patients had a nephrologist. Using a screening tool based on the 2012 Kidney Disease Improving Global Outcomes guidelines, a nurse care manager (NCM) made recommendations about management including indications for referral. A pharmacist reviewed patients' charts and made medication-related recommendations. Blue Cross Blue Shield (BCBS) insurance provided cost data for a subset of patients. RESULTS: A total of 1,255 patients were identified. Half did not have a formal diagnosis of CKD and three-quarters had never seen a nephrologist. Based on the results of the screening tool, the NCM recommended nephrology E-consult or full consult for 85 patients. The subset of BCBS patients had a mean healthcare cost of $1,528.69 per member per month. CONCLUSIONS: We implemented a PCMN that allowed for easy identification of a high-risk, high-cost population of CKD patients and optimized their care to reflect guideline-based standards.

Critically Evaluating the Role for Postoperative Antibiotics in Patients Undergoing Urethroplasty With Buccal Mucosa Graft: A Claims Database Analysis.

OBJECTIVE: To compare outcomes among patients undergoing first-time urethroplasty with buccal mucosa graft (BMG) who receive postoperative antibiotics vs those who do not. METHODS: A retrospective cohort study was conducted using the TriNetX claims database between 2008-2022. Using CPT, ICD10, and LOINC codes, patients >18 years old undergoing primary urethroplasty with BMG who received an outpatient prescription for antibiotics between postoperative day 0-30 or did not were queried. Patients with positive preoperative urine culture or urinary tract infection (UTI) within 30days preoperatively were excluded. Surgical outcomes included 5-year revision rates and revision-free survival. Safety outcomes included new UTI within 30days, surgical site infection within 90days, or Clostridium difficile infection within 30days of urethroplasty. RESULTS: We identified 884 patients (81% antibiotic cohort, 19% nonantibiotic cohort) that met inclusion criteria. Age at time of urethroplasty, suprapubic tube presence, and pre-existing medical comorbidities were comparable between cohorts (Table 1A). There was no difference in 5-year rates and revision-free survival for endoscopic revision (11.5% vs 9.5%, relative risk (RR) 1.2, 95% CI [0.7, 2.0], recurrence-free survival (RFS) log-rank P = .6), re-do urethroplasty (12.9% vs 13.7%, RR 0.9, 95% CI [0.6, 1.5], RFS log-rank P = .7), or all-cause revision (19.8% vs 17.7%, RR 1.1, 95% CI [0.8, 1.6], P = .5) between groups. Postoperative rates of UTI, surgical site infection, and C difficile infection were similar between groups. CONCLUSION: In this large retrospective cohort study of patients undergoing urethroplasty with BMG, we observed no significant benefit from use of postoperative antibiotics on long-term revision rates or perioperative infectious complications.

The Impact of Hypogonadism on Surgical Outcomes Following Primary Urethroplasty: Analysis of a Large Multi-institutional Database.

OBJECTIVE: To compare surgical outcomes among a cohort of eugonadal and hypogonadal patients undergoing primary urethroplasty (UP). METHODS: A retrospective cohort study was conducted using TriNetX between 2008-2023. Patients who were eugonadal and hypogonadal (symptoms plus testosterone <300 ng/dL) prior to UP were compared. A subgroup analysis of hypogonadal patients was performed to compare those with testosterone replacement therapy (TRT) vs TRT-naïve prior to UP. Propensity-score matching was used to adjust for differences in comorbidities. Outcomes were 5-year revision rates and revision-free survival for endoscopic revision and redo UP following primary UP. RESULTS: We identified 12,556 eugonadal and 488 hypogonadal patients (153 TRT+, 335 TRT-) undergoing UP. Median age at UP and follow-up was 55years and 5years, respectively. After propensity-score matching, we compared 477 eugonadal and 477 hypogonadal patients. Hypogonadal patients had a statistically significantly higher 5-year redo UP rate (11% vs 6%, relative risk [RR] 1.5 [95%CI, 1.2-2.2]; P = .01) when compared to eugonadal patients however there was no difference in 5-year rates of endoscopic revision (11% vs 11%, RR 1.0 [95%CI, 0.7-1.5]; P = 1.0). We observed no difference in 5-year revision-free survival time for endoscopic revision or redo UP between groups. Hypogonadal patients treated with TRT had a significantly higher 5-year redo UP rate (15% vs 7%, RR 1.8 [95%CI, 1.1-3.3]; P = .02) compared to hypogonadal patients that were TRT-naïve prior to UP. There was no difference in rates of endoscopic revision (14% vs 10%, RR 1.3 [95%CI, 0.7-2.4]; P = .2) between subgroups. CONCLUSION: Pre-existing hypogonadism may modestly adversely affect surgical outcomes following primary UP based on data from a large, retrospective cohort study.

Early Post-Operative Events After Urethroplasty in Obese Patients: A Multi-Institutional Retrospective Series.

OBJECTIVE: To compare early urethroplasty outcomes in non-obese, obese and morbidly obese patients undergoing urethroplasty for urethral stricture disease. The impact of obesity on outcomes is poorly understood but will be increasingly important as obesity continues to rise. METHODS: Patients underwent urethroplasty at one of the 5 institutions between January 2016 and December 2020. Obese (BMI 30-39.9, n = 72) and morbidly obese (BMI >40, n = 49) patients were compared to normal weight (BMI <25, n = 29) and overweight (BMI 25-29.9, n = 51) patients. Demographics, comorbidities, and stricture characteristics were collected. Outcomes including complications, recurrence, and secondary interventions were compared using univariate and multivariate analysis. RESULTS: Two hundred and one patients (Mean BMI 34.1, Range 18.4-65.2) with mean age 52.2 years (SD=17.2) were analyzed. Median follow-up time was 3.71 months. Obese patients were younger (P = .008), had more anterior (P <.001), iatrogenic and LS-associated strictures (P = .036). Sixty-day complication rate was 26.3% with no differences between cohorts (P = .788). Around 9.5% of patients had extravasation at catheter removal, 18.9% reported stricture recurrence, and 7.4% required additional interventions. Obese patients had greater estimated blood loss (P = .001) and length of stay (P = .001). On multivariate analysis, smoking associated with contrast leak (OR 7.176, 95% CI 1.13-45.5) but not recurrence or need for intervention (P = .155, .927). CONCLUSION: Obese patients in our cohort had more anterior, iatrogenic, and LS-related strictures. However, obesity is not associated with complications, contrast leak, secondary interventions, or recurrence. Obese had higher blood loss and length of stay. Urethroplasty is safe and effective in obese patients.

Transperineal Versus Transrectal Magnetic Resonance Imaging-targeted and Systematic Prostate Biopsy to Prevent Infectious Complications: The PREVENT Randomized Trial.

BACKGROUND AND OBJECTIVE: The transrectal biopsy approach is traditionally used to detect prostate cancer. An alternative transperineal approach is historically performed under general anesthesia, but recent advances enable transperineal biopsy to be performed under local anesthesia. We sought to compare infectious complications of transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis. METHODS: We assigned biopsy-naïve participants to undergo transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis (rectal culture screening for fluoroquinolone-resistant bacteria and antibiotic targeting to culture and sensitivity results) through a multicenter, randomized trial. The primary outcome was post-biopsy infection captured by a prospective medical review and patient report on a 7-d survey. The secondary outcomes included cancer detection, noninfectious complications, and a numerical rating scale (0-10) for biopsy-related pain and discomfort during and 7-d after biopsy. KEY FINDINGS AND LIMITATIONS: A total of 658 participants were randomized, with zero transperineal versus four (1.4%) transrectal biopsy infections (difference -1.4%; 95% confidence interval [CI] -3.2%, 0.3%; p = 0.059). The rates of other complications were very low and similar. Importantly, detection of clinically significant cancer was similar (53% transperineal vs 50% transrectal, adjusted difference 2.0%; 95% CI -6.0, 10). Participants in the transperineal arm experienced worse periprocedural pain (0.6 adjusted difference [0-10 scale], 95% CI 0.2, 0.9), but the effect was small and resolved by 7-d. CONCLUSIONS AND CLINICAL IMPLICATIONS: Office-based transperineal biopsy is tolerable, does not compromise cancer detection, and did not result in infectious complications. Transrectal biopsy with targeted prophylaxis achieved similar infection rates, but requires rectal cultures and careful attention to antibiotic selection and administration. Consideration of these factors and antibiotic stewardship should guide clinical decision-making. PATIENT SUMMARY: In this multicenter randomized trial, we compare prostate biopsy infectious complications for the transperineal versus transrectal approach. The absence of infectious complications with transperineal biopsy without the use of preventative antibiotics is noteworthy, but not significantly different from transrectal biopsy with targeted antibiotic prophylaxis.

Robotic-Assisted Augmented Roof Ureteroplasty With Appendiceal Onlay Flap.

BACKGROUND: Mid-to-proximal ureteral strictures pose a surgical challenge that historically required ileal ureter substitution, downward nephropexy, or renal autotransplantation. Ureteral reconstruction techniques involving buccal mucosa or appendix have gained traction with success rates approaching 90%. OBJECTIVES: In this video we describe surgical technique for a robotic-assisted augmented roof ureteroplasty using an appendiceal onlay flap. MATERIALS AND METHODS: Our patient is a 45-year-old male with recurrent impacted ureteral stones requiring multiple right-sided interventions including ureteroscopy with laser lithotripsy, ureteral dilation, and laser incision of ureteral stricture. Despite adequate treatment of his stone disease, he had deterioration of his renal split function with worsening right hydroureteronephrosis to the level of the mid-to-proximal ureter consistent with failed endoscopic management of his stricture. We proceeded with simultaneous endoscopic evaluation and robotic repair with plan for either ureteroureterostomy or augmented roof ureteroplasty using buccal mucosa or an appendiceal flap. RESULTS: Reteroscopy and retrograde pyelogram revealed a 2-3 cm near-obliterative stricture in the mid-to-proximal ureter. The ureteroscope was left in situ and the patient was placed in the modified flank position to allow concurrent endoscopic access during reconstruction. The right colon was reflected revealing significant scar tissue overlying the ureter. With the ureteroscope in situ, we utilized firefly imaging to aid in our dissection. The ureter was spatulated and mucosa of the diseased segment of ureter excised in a nontransecting manner. The mucosal edges of the posterior ureter were re-approximated with the ureteral backing left in place. Intraoperatively, we identified a healthy, robust appearing appendix and thus planned for an appendiceal onlay flap. If an atretic or diseased appendix was encountered, a buccal mucosa graft with omental wrap would be utilized. The appendix was harvested on its mesentery, spatulated, and interposed in a pro-peristaltic fashion. A tension-free anastomosis was performed between ureteral mucosa and the open appendix flap. A double-J stent was placed under direct vision and Indocyanine Green (ICG) green was used to evaluate blood supply to the margins of the ureter and the appendix flap. The stent was removed 6 weeks postoperatively, and on 3-month follow-up imaging he had resolution of his right hydroureteronephrosis and has had no further episodes of stone formation, infections, or flank pain with 8-month follow-up. CONCLUSION: Augmented roof ureteroplasty with appendiceal onlay is a valuable tool in the urologists arsenal of reconstructive techniques. Use of intraoperative ureteroscopy with firefly imaging can aid in delineating anatomy during difficult ureteral dissections.
