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 develop an internationally validated, structured robot‐assisted radical nephroureterectomy (RARNU) training programme through expert consensus. Materials and Methods A RARNU‐specific questionnaire was developed/adapted from previously published, validated questionnaires for robot‐assisted urological procedures. This included five key domains and 11 surgical steps. In all, 30 upper tract urothelial carcinoma experts were invited to participate. A two‐stage modified Delphi approach was employed. Consensus was defined as ≥80% agreement. Modifications and additional statements were proposed during the second round following qualitative/quantitative feedback from the initial round. Results Response rates for the first and second Delphi rounds were 80% (24/30) and 92% (22/24), respectively. All agreed that adoption of a standardised training curriculum can improve clinical outcomes during the RARNU learning curve. There was ≥92% agreement on all proposed RARNU steps. Five RARNU clinical modules of increasing complexity were defined using individual step difficulty and number of prior RARNU cases required, with ≥96% agreement among respondents. Respondents unanimously agreed that the final assessment should be based on a procedure‐specific scale focusing on the hilar dissection, ureteric dissection, and bladder cuff excision steps. No consensus was reached for the annual minimum RARNU volume required for eligibility as a RARNU curriculum host centre. Conclusion This is the first structured training curriculum for RARNU using international expert consensus. This will help guide surgical educators and trainees toward independent completion of a full RARNU.

Radiologists play a key role in the management of renal masses, and it is important to understand the nonsurgical treatment options for solid renal masses, typical imaging findings after treatment, common complications, and methods to avoid pitfalls.

Background: Although previous literature shows tumor location as a prognostic factor in upper tract urothelial carcinoma (UTUC), there remains uninvestigated regarding the impact of tumor location on grade concordance and discrepancies between ureteroscopic (URS) biopsy and final radical nephroureterectomy (RNU) pathology. Methods: In this international study, we retrospectively reviewed the records of 1,498 patients with UTUC who underwent diagnostic URS with concomitant biopsy followed by RNU between 2005 and 2020. Tumor location was divided into four sections: the calyceal-pelvic system, proximal ureter, middle ureter, and distal ureter. Patients with multifocal tumors were excluded from the study. We performed multiple comparison tests and logistic regression analyses. Results: Overall, 1,154 patients were included; 54.4% of those with low-grade URS biopsies were upgraded on RNU. In the multiple comparison tests, middle ureter tumors exhibited the highest probability of upgrading, meanwhile pelvicalyceal tumors exhibited the lowest probability of upgrading (73.7% vs 48.5%, p = 0.007). Downgrading was comparable across all tumor locations. On multivariate analyses, middle ureteral location was significantly associated with a low probability of grade concordance (odds ratio [OR] 0.59; 95% confidence interval [CI], 0.35–1.00; p = 0.049) and an increased risk of upgrading (OR 2.80; 95% CI, 1.20–6.52; p = 0.017). The discordance did not vary regardless of caliceal location, including the lower calyx. Conclusions: Middle ureteral tumors diagnosed to be low grade had a high probability to be undergraded. Our data can inform providers and their patients regarding the likelihood of undergrading according to tumor location, facilitating patient counseling and shared decision making regarding the choice of kidney sparing vs RNU.

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.
