High-Risk Patients Undergoing Holmium Laser Enucleation of the Prostate Have Fewer Infections with a Longer Course of Preoperative Antibiotics.

Introduction: There are minimal data to guide antibiotic management of patients undergoing holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia. Specifically, management of high-risk patients who are catheter dependent or have positive preoperative urine cultures varies widely. We aimed to evaluate the effect of preoperative antibiotic duration on infectious complications in high-risk patients undergoing HoLEP. Methods: A multi-institutional retrospective review of patients undergoing HoLEP between 2018 and 2023 at five institutions was performed. Patients were defined as high risk if they were catheter-dependent (indwelling urethral catheter, self-catheterization, or suprapubic tube) or had a positive preoperative urine culture. These patients were categorized into long course (>3 days) or short course (≤3 days) of preoperative antibiotics. The primary outcome was 30-day infectious complications defined as a positive urine culture with symptoms. A t-test or Wilcoxon rank-sum test was used for continuous variables and Fisher's exact test was used for categorical variables. Logistic regression analysis was conducted to identify associations with infectious complications. Results: Our cohort included 407 patients, of which 146 (36%) and 261 (64%) were categorized as short course and long course of preoperative antibiotics, respectively. Median preoperative antibiotic duration was 1 day (interquartile range [IQR]: 0, 3 days) and 7 days (IQR: 5, 7 days) in the short and long cohorts, respectively. Thirty-day postoperative infectious complications occurred in 11 (7.6%) patients who received a short course of antibiotics and 5 (1.9%) patients who received a long course of antibiotics (odds ratio 0.24, 95% confidence interval 0.07-0.67; p = 0.009). Variables such as age, positive urine culture, and postoperative antibiotic duration were not significantly associated with postoperative infection after propensity score weighting. Conclusion: In high-risk patients undergoing HoLEP, infectious complications were significantly lower with a long course vs short course of antibiotics. Further prospective trials are needed to identify optimal preoperative antibiotic regimens.

A Feasibility Study to Evaluate Changes in Urinary Metabolites after OnabotulinumtoxinA Injection for Refractory Overactive Bladder.

Metabolomics analysis of urine before and after overactive bladder (OAB) treatment may demonstrate a unique molecular profile, allowing predictions of responses to treatment. This feasibility study aimed to correlate changes in urinary metabolome with changes in OAB symptoms after intravesical onabotulinumtoxinA (BTX-A) injections for refractory OAB. Women 18 years or older with non-neurogenic refractory OAB were recruited to complete OAB-V8 questionnaires and submit urine samples before and after 100 units intravesical BTX-A injection. Samples were submitted to CE-TOFMS metabolomics profiling. Data were expressed as percent of change from pre-treatment and were correlated with OAB-V8 score improvement. Urinary metabolite changes in the OAB-V8 groups were compared using the Kruskal-Wallis test, and associations between metabolites and OAB-V8 scores were examined using quantile regression analysis. Of 61 urinary metabolites commonly detected before and after BTX-A, there was a statistically significant decrease in adenosine and an increase in N8-acetylspermidine and guanidinoacetic acid levels associated with OAB score improvement, suggesting that intravesical BTX-A injection modifies the urinary metabolome. These urinary metabolites could provide insight into OAB pathophysiology and help identify patients who would benefit most from chemodenervation.

Gender Bias in YouTube Videos Describing Common Urology Conditions.

OBJECTIVE: To study implicit and explicit gender biases in YouTube videos describing common urologic conditions based on language patterns, speaker gender, and speaker profession. METHODS: Using a Boolean search, the top 30 videos for benign prostatic hyperplasia (BPH), kidney stones, urinary tract infections (UTIs), overactive bladder (OAB), erectile dysfunction (ED), and pelvic organ prolapse (POP) were retrieved. Using the Linguistic Inquiry and Word Count program (LIWC) software, video transcripts were analyzed for 16 word categories and compared by speaker gender and urology topic to assess for bias. RESULTS: OAB and POP had the least view counts and subscribers; kidney stone and ED videos had the most. Student education channels were more likely to feature male than female speakers (19 male vs. 6 female, P=0.01). A significant difference was noted between speaker gender in BPH (25 male vs. 4 female, P<0.001), OAB (4 male vs. 22 female, P<0.001), and POP (6 male vs. 23 female, P<0.001) videos. When examining linguistic patterns with the LIWC program, female speakers were more likely to mention personal concerns and use tentative words when speaking alone compared to males. CONCLUSIONS: Gender bias exists in YouTube videos concerning common urologic conditions. We must be mindful of how information is distributed in order to minimize the perpetuation of gender stereotypes that are common in medicine. Awareness of these patterns and biases should encourage Urologists to proactively consider how they present themselves and how they reference the conditions they present in social media outlets.

Sex-Based Language Differences in Female Pelvic Medicine and Reconstructive Surgery Fellowship Recommendation Letters.

INTRODUCTION: Letters of recommendation (LORs) are a significant component of residency and fellowship applications. Applicant sex may play a role in the language used in letters, which could hinder progress in academic fields, particularly for women. Although differences in language based on applicant sex have been identified in other fields, no prior studies have evaluated LORs for female pelvic medicine and reconstructive surgery (FPMRS) fellowships. METHODS: Letters of recommendations for applicants to an urban, tertiary care academic medical FPMRS fellowship from 2017 to 2019 were collected. Using the Linguistic Inquiry and Word Count program, a licensed text analysis software for academic purposes, we analyzed LORs based on 16 categories. The Wilcoxon rank sum test, Fisher exact test, and a generalized linear mixed model were used for statistical analyses. RESULTS: A total of 97 fellowship applications were analyzed, yielding 354 LORs; 32 applicants were male, whereas 65 were female. Letters written for male applicants contained significantly more power words (P = 0.022) and significantly less affiliation words (P = 0.025) compared with female counterparts. Differences were maintained after adjusting for age, race/ethnicity, step 1 to step 3 scores, Phi Beta Kappa status, Alpha Omega Alpha status, and writer's sex. CONCLUSIONS: Significant linguistic differences based on applicant sex exist in FPMRS fellowship LORs. Differences are consistent with previous analyses within science and medical fields. These findings did not show a significant association with an applicant's ability to match; however, we did not analyze whether the matched institution was the preferred choice for each applicant.
