Abstract
In urological surgery, the Da Vinci Xi robotic system has many advantages, but it also has limitations such as high equipment costs and the need for professional training. Kangduo is a laparoscopic surgical robot developed in China, and SR2000 is its newly approved four-arm laparoscopic surgical robot. This study compares the short-term outcomes of the two in radical cystectomy. Data from a centre-based randomised non-inferiority trial were used and patients between March 2023 and June 2024 were enrolled and randomised according to criteria. The primary outcome was surgical success, and secondary outcomes included intraoperative variables, surgical outcomes, pathological outcomes, and postoperative outcomes. A total of 34 patients, 16 in the KD group and 18 in the DV group, had no intermediate open or conventional laparoscopic surgery, and the surgical success rate was 100%, with no significant differences between the two groups in many aspects. The effectiveness and safety of the KangDuo SR2000 system were demonstrated. Experienced surgeons confirmed that performing radical cystectomy using the KangDuo SR2000 system yielded results comparable to those achieved using the Da Vinci robotic system.
