Da Vinci vs. Hugo RAS for robot-assisted radical prostatectomy: a prospective comparative single-center study

Abstract

Purpose: To evaluate Hugo RAS against the Da Vinci system for Robot-Assisted Radical Prostatectomy (RARP) in prostate cancer treatment.

Methods: We compared outcomes of 150 patients with prostate cancer undergoing RARP with either Hugo or Da Vinci systems. Our analysis included operative, postoperative, pathological, and functional outcomes.

Results: Both groups had 75 patients. Baseline characteristics and tumor features were similar. Intraoperatively, Da Vinci had a shorter docking time (10.45 vs. 18.62 min, p = 0.02), but total operative times were comparable (145.34 vs 138.95, p = 0.85). Hugo outperformed in neck dissection and lymphadenectomy times (22 vs 13.67 min, p = 0.027 and 37.82 vs 45.77 min, p = 0.025). Postoperative metrics like stay duration, catheter time, and complications showed no significant difference. Functional results, using IPSS and IIEF5, were similar between systems. Six Da Vinci patients (8%) and nine Hugo patients (12%) experienced social incontinence (p = 0.072). Pathological outcomes like T stage, Gleason Score, and nodes removed were alike. However, Hugo had more positive surgical margins (20% vs. 10.67%, p = 0.034).

Conclusions: RARP outcomes using Hugo RAS were similar to the Da Vinci system in our study. More research and extended follow-up are required to ascertain long-term oncological and functional results.
