Comparison of YouTube videos on single-port and multi-port robot-assisted radical prostatectomy using the PACE score.

This study aimed to compare the PACE-based procedural demonstration quality of YouTube videos demonstrating single-port robot-assisted radical prostatectomy (SP-RARP) and multi-port robot-assisted radical prostatectomy (MP-RARP). A cross-sectional analysis of publicly available YouTube videos was performed between January 1 and January 15, 2026. Videos containing real operative footage of SP-RARP or MP-RARP were included only if all seven PACE domains could be assessed. Selected procedural-segment videos were defined as edited operative videos that still included all PACE steps; videos with missing or non-assessable PACE domains were excluded. Video characteristics, source, procedure type, narration, and on-screen annotations were recorded. Comparisons between groups and correlations with total PACE score were analyzed. A total of 141 videos were included: 43 SP-RARP and 98 MP-RARP videos. MP-RARP videos were significantly longer (60 vs. 28 min, p < 0.001), older (2096 vs. 1095 days, p < 0.001), and received more likes (p = 0.029). Academic or official sources were more common among SP-RARP videos (69.8% vs. 51.0%, p = 0.044). Total PACE scores were similar between groups (25.86 ± 5.48 vs. 26.50 ± 4.37, p = 0.501). SP-RARP videos had higher scores for apical dissection and urethro-vesical anastomosis. In MP-RARP videos, video length correlated positively with total PACE score. SP-RARP and MP-RARP videos showed comparable overall PACE-based demonstration quality, although SP-RARP better demonstrated apical dissection and urethro-vesical anastomosis. Step-based assessment appears more useful than engagement metrics when selecting RARP videos.
