Purpose: Robot-assisted laparoscopy (RALP), conventional laparoscopy (LP), and balloon dilation (BD) have all been identified as common treatments for benign ureteral stricture (BUS). The purpose of the research would be to compare the safety and efficacy differences in the three groups. Patients and Methods: Patients who received RALP, LP, or BD for BUS were studied retrospectively from January 2016 through December 2020. Professional and experienced surgeons performed all operations. We collect and analyze baseline characteristics, stricture details, and perioperative and follow-up information. Results: The results showed no statistically significant difference between the three groups for baseline characteristics and stricture details. No statistical difference was also found between RALP and LP in specific surgical techniques. The average operative time was longer in the LP group than RALP and BD groups (178 minutes vs 150 minutes vs 67 minutes, respectively, p < 0.001). BD had lower estimated blood loss than RALP and LP (14 mL vs 40 mL vs 32 mL, p < 0.001) and similar between the RALP and LP groups (p = 0.238). The BD group had the shortest postoperative hospital stay compared with the RALP and LP groups (2.95 days vs 5.25 days vs 6.52 days, p < 0.001), and no statistically significant difference existed between the RALP and LP groups (p = 0.098). RALP had considerably greater hospitalization expenses than both LP (p < 0.001) and BD (p < 0.001). Complications and short-term success rates (6 months) were similar. The BD group had poorer long-term success (12 and 24 months) than the RALP and LP groups, whereas there was no statistically significant difference between the RALP and LP groups. Conclusions: For the management of BUS, RALP, LP, and BD are all safe and effective, with equivalent complication rates and short-term success. In long-term success rates, BD is low than RALP and LP.
