  "abstract": "Purpose: To compare perioperative outcomes of intracorporeal (ICUD) versus extracorporeal urinary diversion (ECUD) following robot-assisted radical cystectomy (RARC) in localized bladder cancer, using the Korean RARC (KORARC) Study Group database.\n\nMethods: Patient characteristics, intraoperative details, and perioperative outcomes were compared between ICUD and ECUD groups. The primary outcome was postoperative complications; secondary outcomes were operative time, hospital stay, estimated blood loss (EBL), and transfusion rate. Multivariate regression adjusted for potential confounders, and subgroup analyses stratified by urinary diversion type were performed.\n\nResults: Of 703 patients undergoing RARC between 2007 and 2019, 26.5% had ICUD and 73.5% had ECUD. Overall complication rates were similar (52.7% vs. 60.0%, p = 0.101), but ICUD showed fewer late complications (30–90 days; 30.1% vs. 38.9%, p = 0.041) and longer operative time (494.6 ± 120.6 vs. 417.9 ± 136.6 min, p < 0.001). On multivariate analysis, ICUD was independently associated with reduced late complications (Odds ratio [OR] 0.68, 95% confidence interval [CI]: 0.47–0.97, p = 0.034), without affecting minor, major, or overall complication risks. In diversion-stratified analyses, ICUD required longer operative time in both ileal conduit (514.6 vs. 453.8 min, p < 0.001) and neobladder (470.6 vs. 405.6 min, p < 0.001) subgroups. EBL was higher with ICUD in the ileal conduit subgroup (p = 0.034) but lower in the neobladder subgroup (p = 0.003). The protective effect on late complications was confined to the ileal conduit subgroup (adjusted OR 0.60, 95% CI 0.38–0.95, p = 0.029) and not observed in the neobladder subgroup (OR 0.76, p = 0.462).\n\nConclusion: Although associated with longer operative time, ICUD may reduce late postoperative complications compared with ECUD without compromising perioperative safety or oncological outcomes after RARC.\n\nSupplementary Information: The online version contains supplementary material available at https://doi.org/10.1007/s00345-026-06550-7.",
