Robot-assisted laparoscopic radical prostatectomy using the KangDuo surgical robot system versus the da Vinci Si robotic system.

To compare the efficacy and safety of robot-assisted laparoscopic radical prostatectomy (RARP) performed using the KangDuo surgical robot system to the da Vinci Si robotic system in clinically localized prostate cancer (KD-RARP vs. DV-RARP).

A total of 16 patients underwent extraperitoneal KD-RARP performed by a single experienced surgeon using the KangDuo surgical robot system between May 2021 and August 2021. The data were prospectively collected. The most recent 16 cases of extraperitoneal DV-RARP performed in 2021 by the same surgeon were selected from a prospectively maintained database for comparison to prevent operator variability. Preoperative, perioperative, and postoperative data were collected and compared between the two groups.

No significant difference was noted between the two groups in terms of basic clinical characteristics. All operations were performed successfully without open or traditional laparoscopic conversion. KD-RARP had a significantly longer operation time compared to DV-RARP [127 (107-159) vs. 70.5 (54-90) min, p<0.001]. No significant differences between the two groups were observed in neurovascular bundle sparing, estimated blood loss, postoperative hospital stay duration, complications, positive surgical margins, biochemical recurrence, and continence recovery 3 months after catheter removal.

RARP using the KangDuo surgical robot system achieved similar short-term oncological and functional outcomes with a disadvantage in operation time compared to the da Vinci Si robotic system. A multicenter randomized clinical trial with a larger sample size is needed for more experience.
