[Application of China-made Toumai Robot in laparoscopic radical prostatectomy]

To evaluate the safety and efficiency of China-made Toumai Robot-assisted laparoscopic radical prostatectomy (LRP).

This study included 40 cases of PCa treated from January 2023 to May 2023 by robot-assisted LRP with preservation of the bladder neck and maximal functional urethral length, 15 cases with the assistance of Toumai Robot (the TMR group) and the other 25 with the assistance of da Vinci Robot as controls (the DVR group). We recorded the docking time, laparoscopic surgery time, vesico-urethral anastomosis time, intraoperative blood loss and postoperative urinary continence, and compared them between the two groups.

Operations were successfully completed in all the cases. No statistically significant differences were observed between the TMR and DVR groups in the docking time (6 min vs 5 min, P > 0.05) or intraoperative blood loss (200 ml vs 150 ml, P > 0.05). The TMR group, compared with the DVR group, showed a significantly longer median laparoscopic surgery time (146 min vs 130 min, P < 0.05) and median vesico-urethral anastomosis time (19 min vs 16 min, P < 0.05). There were no statistically significant differences between the TMR and DVR groups in the rates of urinary continence recovery immediately after surgery (60.0% ［9/15］ vs 64.0% ［16/25］, P > 0.05) or at 1 month (80.0% ［12/15］) vs (76.0% ［19/25］, P > 0.05), 3 months (93.3% ［14/15］) vs (92.0% ［23/25］, P > 0.05) and 6 months postoperatively (100% ［15/15］) vs (96% ［24/25］, P > 0.05).

China-made Toumai Robot surgical system is safe and reliable for laparoscopic radical prostatectomy, with satisfactory postoperative recovery of urinary continence.
