Purpose: Surgical video review can be used in urologic training, yet significant barriers to the implementation of video review programs exist, and formal assessment of usage and utility for trainees is limited. Here, we evaluate a novel video review platform to describe patterns of use and determine perceived utility. Materials and Methods: We analyzed learning points entered by trainees during video review of radical prostatectomy cases using our surgical intelligence–enabled Film Room platform between September 2023 and July 2024. Learning point content was categorized according to surgical coaching domains as technical, cognitive, nontechnical, or descriptive. Entries were compared by surgical step and level of training. Anonymous surveys were distributed to trainees to determine perceived utility and reveal patterns of video review. Results: Thirteen trainees entered 480 unique learning points across all radical prostatectomy steps and spanning surgical coaching domains during the study period. Learning points varied by training level, with junior trainees entering points more often than senior trainees for Retzius-space dissection ( N = 73 vs 17, p < 0.01) and seminal vesicle and posterior dissection ( N = 58 vs 27, p < 0.01). Trainees used video review in preparation for both upcoming cases and performance analysis. Ninety-four percent of survey respondents reported they either agreed or strongly agreed that video review helped them develop surgical skills. Conclusions: We found usage across training levels and high perceived utility of our Film Room platform for video review of robotic prostatectomy. Implementation of video review platforms holds promise to augment existing urologic training and should be explored further.

Objectives To characterise the prevalence of impostor phenomenon (IP; tendency for high‐achieving individuals to perceive themselves as fraudulent in their successes) amongst attending staff in urology, to identify variables that predict more severe impostorism, and to study the association of IP with burnout. Subjects and Methods A survey composed of the Clance Impostor Phenomenon Scale (CIPS), demographic information, practice details, and burnout levels was e‐mailed to urologists via urological subspecialty societies. Survey results were analysed to identify associations between IP severity, survey respondent characteristics, and symptoms of professional burnout. This study was conducted in the United States of America. Results A total of 614 survey responses were received (response rate 11.0%). In all, 40% ( n = 213) of responders reported CIPS scores qualifying as either ‘frequent’ or ‘intense’ impostorism (i.e., scores of 61–100). On multivariable analysis, female gender, fewer years in practice (i.e., 0–2 years), and lower academic rank were all independently associated with higher CIPS scores (adjusted P < 0.05). Regarding burnout, 46% of responders reported burnout symptoms. On multivariable analysis, increase in CIPS score was independently associated with higher odds of burnout (odds ratio 1.06, 95% confidence interval 1.04–1.07; P < 0.001). Conclusion Impostor phenomenon is prevalent in the urological community and is experienced more severely in younger and female urologists. IP is also independently associated with burnout. Increased female representation may improve IP amongst our female colleagues. More work is needed to determine strategies that are effective in mitigating feelings of IP and professional burnout amongst urologists, particularly those earlier in their careers.

Objectives To compare the carbon footprint and environmental impact of single‐use and reusable flexible cystoscopes. Materials and Methods We analysed the expected clinical lifecycle of single‐use (Ambu aScope™ 4 Cysto) and reusable (Olympus CYF‐V2) flexible cystoscopes, from manufacture to disposal. Performance data on cumulative procedures between repairs and before decommissioning were derived from a high‐volume multispecialty practice. We estimated carbon expenditures per‐case using published data on endoscope manufacturing, energy consumption during transportation and reprocessing, and solid waste disposal. Results A fleet of 16 reusable cystoscopes in service for up to 135 months averaged 207 cases between repairs and 3920 cases per lifecycle. Based on a manufacturing carbon footprint of 11.49 kg CO 2 /kg device for reusable flexible endoscopes and 8.54 kg CO 2 /kg device for single‐use endoscopes, the per‐case manufacturing cost was 1.37 kg CO 2 for single‐use devices and 0.0017 kg CO 2 for reusable devices. The solid mass of single‐use and reusable devices was 0.16 and 0.57 kg, respectively. For reusable devices, the energy consumption of reusable device reprocessing using an automated endoscope reprocessor was 0.20 kg CO 2 , and per‐case costs of device repackaging and repair were 0.005 and 0.02 kg CO 2 , respectively. The total estimated per‐case carbon footprint of single‐use and reusable devices was 2.40 and 0.53 kg CO 2 , respectively, favouring reusable devices. Conclusion In this lifecycle analysis, the environmental impact of reusable flexible cystoscopes is markedly less than single‐use cystoscopes. The primary contributor to the per‐case carbon cost of reusable devices is energy consumption of reprocessing.

Introduction: Patients who form kidney stones are typically advised to limit intake of nondairy animal protein. Plant-based meat products may be a processed substitute protein source for these patients and have recently gained popularity because of health concerns, increased retail availability, decreased environmental impact, and meat supply shortages during the COVID-19 pandemic. Despite these perceived benefits and tangential association with whole food plant-based diets, the potential lithogenic risks associated with these products are not well characterized. Methods: The U.S. Department of Agriculture database was queried with a sample of plant-based meat products widely available to U.S. consumers. Nutrient profile data were compiled and compared with animal protein data using standardized serving sizes. Primary protein sources were identified using verified ingredient lists. Oxalate content was extrapolated based on dietary data sources. Results: A total 47 plant-based meat products (16 beef, 11 pork, 10 chicken, and 10 seafood) were analyzed. Compared with their respective animal protein, most products contained on average fewer calories (plant-based beef 77%, pork 94%, chicken 86%, and seafood 83%) and less protein (plant-based beef 68%, pork 96%, chicken 53%, and seafood 54%). Most products used soy protein as the primary protein source (55%). Soy-based beef contained the highest average oxalate content (18 mg per serving), whereas soy-based seafood contained the lowest (7 mg). The most common non-soy protein source was pea protein (30%), containing trace amounts of oxalate. Sodium content was higher in most plant-based products overall (72%) and in each category (plant-based beef 109%, pork 128%, chicken 100%, and seafood 148%). Calcium content was higher (plant-based beef 317%, pork 144%, chicken 291%, and seafood 295%) compared with animal protein. Conclusions: Most plant-based meat products consist of protein sources that are, relative to animal protein sources, higher in oxalate, sodium, and calcium. Stone-forming patients should be counseled about the potential lithogenic risk of these processed products.
