Implementation of Robot-assisted Urologic Surgeries Using Hugo RAS System in a High-volume Robotic "Da Vinci Xi" Center: Outcomes and Initial Experience.

ABSTRACT

OBJECTIVE: To describe the trocar disposition, docking angles, surgical times, functional outcomes, and complications experienced during the first 30 surgeries with Hugo RAS platform performed by a high-volume Da Vinci Xi's surgeon. METHODS: Retrospective, observational, descriptive study was performed between May-December 2023. Safety and feasibility of the procedures were evaluated considering console and docking time (minutes), perioperative complications (Clavien-Dindo classification), blood loss (mL), and collision of the arms during the procedures (Yes/No). For radical prostatectomies (RARP) the urinary continence and sexual function were also evaluated. RESULTS: RARP, simple prostatectomies (RASP), partial nephrectomies (RAPN), and cystectomy (RARC) were performed. Trocar placement, docking, and bed assistant ergonomics were important challenges. Patient positioning, trocar placement, and robotic arm positioning had to be adapted. The median console operative time for RARP and RASP was 78 (60-120) minutes and 79 (58-125) minutes, respectively. The median docking time for both RARP and RASP was 10 (5-20) minutes. Of patients undergoing RARP, 94.5% recovered sexual function and no patient used more than one PAD per day after 90days of the surgery. The median console operative and docking time for RAPN was 82 (80-130) minutes and 12 (7-19) minutes, respectively. Blood loss in all patients was less than 200 mL and all none procedure presented major complications. CONCLUSION: For a high-volume surgeon with motivated and well-trained multidisciplinary team, the implementation of HUGO RAS system for urological program is safe and smooth. Adaptations were necessary to achieve equivalent surgical technique and results. Docking position and bed assistant ergonomics are the major challenges.
