Comparative analysis of robot-assisted simple prostatectomy: the HUGO™ RAS system versus the DaVinci® Xi system

Abstract

Background: Robot-Assisted Simple Prostatectomy (RASP) has emerged as a promising alternative in the treatment of benign prostatic obstruction (BPO). However, there is currently a lack of comparative studies evaluating different robotic platforms for performing RASP. Therefore, we aimed to compare perioperative and functional outcomes of RASP performed using the HUGO™ RAS System versus the DaVinci® Xi System.

Methods: Forty consecutive cases of RASP performed between May 2021 and March 2023 with the HUGO™ RAS and the DaVinci® Xi at OLV Hospital (Aalst, Belgium) were included in this retrospective study. All surgeries were performed by three experienced surgeons using the same approach. Baseline characteristics, peri-operative and functional outcomes were collected and compared between the two groups.

Results: The population was equally divided between the two groups with 20 patients in each group. There were no significant differences in preoperative patient characteristics between the two groups, except for the presence of bladder stones prior to the surgery (p = 0.03). No significant differences in total operative time and console time between the two groups were reported (p = 0.3). No cases required conversion to open surgery or additional port placement. During one case performed with the HUGO™ RAS, a malfunctioning monopolar curved shear had to be replaced. However, there was no statistically significant differences in terms of technical robotic problems between the groups (p = 0.3). There was no significant difference between the two groups in perioperative and functional outcomes (all p ≥ 0.2).

Conclusions: We did not observe any statistically significant difference in perioperative and functional outcomes in case of RASP performed with the HUGO™ RAS System and with the DaVinci® Xi System. These findings provide compelling support for considering the HUGO™ RAS as a promising tool for robot-assisted procedures, thereby expanding the utilization of robotics for benign conditions.
