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.

Objective: To characterize our single institutional experience with robotic and open uretero-enteric stricture (UES) repair. Materials and Methods: We queried our ureteral reconstructive database for UES repair between 01/2017 and 10/2023. Patients with <3 months follow-up were excluded. Prior to surgery, patients underwent ureteral rest (4 weeks) with conversion to nephrostomy tube. Clinical characteristics, complications, reconstructive success (uretero-enteric patency), need for repeat intervention, and renal function were assessed in patients undergoing open and robotic UES reconstruction. Results: Of 50 patients undergoing UES repair during the study period, 45 were included for analysis due to complete follow-up (34 [76%] robotic and 11 [24%] open repair). UES repair was performed in 50 renal units a median of 13 months (interquartile range 7–30) from index surgery, and most often involved the left renal unit (34/50; 68%). Compared with robotic, open cases were significantly more likely to have undergone open cystectomy (100% vs 68%, p = 0.04), have longer strictures (median 4 vs 1 cm, p < 0.001), require tissue substitution (27% vs 3%, p = 0.04), and have lengthier postoperative hospitalization (5 vs 2 days, p < 0.001). There was no significant difference in total operative time (410 vs 322 minutes) or 30d major complications (18% vs 21%). At a follow-up of 13 months, per patient reconstructive success was 100% (11/11) for open and 97% (33/34) for robotic, respectively. Conclusion: In select patients with short UES unlikely to require advanced reconstructive techniques, a robotic-assisted approach can be considered. Careful patient selection is associated with limited morbidity and high reconstructive success.

ObjectivesTechnical limitations of ureteroscopic (URS) biopsy has been considered responsible for substantial upgrading rate in upper tract urothelial carcinoma (UTUC). However, the impact of tumor specific factors for upgrading remain uninvestigated.MethodsPatients who underwent URS biopsy were included between 2005 and 2020 at 13 institutions. We assessed the prognostic impact of upgrading (low‐grade on URS biopsy) versus same grade (high‐grade on URS biopsy) for high‐grade UTUC tumors on radical nephroureterectomy (RNU) specimens.ResultsThis study included 371 patients, of whom 112 (30%) and 259 (70%) were biopsy‐based low‐ and high‐grade tumors, respectively. Median follow‐up was 27.3 months. Patients with high‐grade biopsy were more likely to harbor unfavorable pathologic features, such as lymphovascular invasion (p < 0.001) and positive lymph nodes (LNs; p < 0.001). On multivariable analyses adjusting for the established risk factors, high‐grade biopsy was significantly associated with worse overall (hazard ratio [HR] 1.74; 95% confidence interval [CI], 1.10–2.75; p = 0.018), cancer‐specific (HR 1.94; 95% CI, 1.07–3.52; p = 0.03), and recurrence‐free survival (HR 1.80; 95% CI, 1.13–2.87; p = 0.013). In subgroup analyses of patients with pT2‐T4 and/or positive LN, its significant association retained. Furthermore, high‐grade biopsy in clinically non‐muscle invasive disease significantly predicted upstaging to final pathologically advanced disease (≥pT2) compared to low‐grade biopsy.ConclusionsHigh tumor grade on URS biopsy is associated with features of biologically and clinically aggressive UTUC tumors. URS low‐grade UTUC that becomes upgraded to high‐grade might carry a better prognosis than high‐grade UTUC on URS. Tumor specific factors are likely to be responsible for upgrading to high‐grade on RNU.
