Purpose: This study aims to compare perioperative and oncologic outcomes between matched cohorts of localized prostate cancer (PCa) operated on by the same surgeon using the da Vinci Si robot and the Revo-i robot. Materials and Methods: Nonmetastatic PCa patients undergoing Retzius-sparing robot-Assisted laparoscopic radical prostatectomy (RS-RARP) from January 2016 to December 2020 were matched one-To-one (33:33) to da Vinci Si controls using propensity score matching according to the following covariates: Age, American Society of Anesthesiology (ASA) score, body mass index, previous abdominal and endoscopic surgery, preoperative prostate specific antigen, prostate volume, Gleason grade group, tumor stage, and need for pelvic lymphadenectomy. Outcomes of interest were estimated blood loss, length of stay, complication rate, operative times, positive surgical margins, and biochemical recurrence at 6 months. Results: Both cohorts were similar in estimated blood loss, rate of margin positivity, and rate of complications. Length of stay was significantly shorter with the Revo-i cohort. The da Vinci robot showed faster console, suture, and total operation times. Positive margin rate and biochemical recurrence at 6 months were similar in both groups. Conclusion: Despite the longer suture, console, and operative time those in the da Vinci robot in the authors' institution, the Revo-i robot-Assisted radical prostatectomy had equivalent short-Term oncologic outcomes with the da Vinci standard.
