Description	Objective: To assess the initial clinical outcomes of robot-assisted radical cystectomy (RARC) at our institution by comparing them with the clinical outcomes of open radical cystectomy (ORC) that used to be performed before its introduction. Methods: We retrospectively identified 64 patients undergoing cystectomy for bladder cancer between 2015 and 2022 and classified them into two groups by treatment method: 32 patients undergoing RARC with ileal conduit urinary diversion (the RARC group) and 32 patients undergoing ORC with ileal conduit urinary diversion (the ORC group). Demographic, perioperative, and pathological data were compared between the two groups. Results: The RARC group had less mean intraoperative blood loss (308 ml vs. 1582 ml, p<0.001), lower mean blood transfusion volume (93 ml vs. 502 ml, p<0.001), larger mean number of resected lymph nodes (28.4 vs. 12.7, p<0.001), and shorter mean postoperative hospital stay (21.8 days vs. 30.8 days, p = 0.049) than the ORC group. There were no significant differences in the operative time, rate of positive surgical margins, and rate of postoperative complications between the two groups. Postoperative complications occurred in 10 patients in the RARC group and 11 patients in the ORC group, and the most common ones were urinary tract infection and postoperative ileus. Conclusion: RARC was more strongly associated with less intraoperative blood loss and lower blood transfusion volume than ORC. RARC may be a feasible and safe treatment method for bladder cancer.
