Robot-assisted radical prostatectomy (RARP) shows improved urinary continence and erectile function recovery compared to laparoscopic radical prostatectomy (LRP). This randomized trial highlights RARP

Area of Science:

  • Urology
  • Surgical Oncology
  • Robotic Surgery

Background:

  • Robot-assisted radical prostatectomy (RARP) versus laparoscopic radical prostatectomy (LRP) advantages are seldom studied in randomized controlled trials.
  • Investigating functional, perioperative, and oncologic outcomes is crucial for surgical decision-making.

Purpose of the Study:

  • To compare RARP and LRP regarding functional, perioperative, and oncologic outcomes.
  • To assess changes in urinary continence at 3 months post-surgery as the primary endpoint.

Main Methods:

  • A randomized controlled trial involving 120 patients with organ-confined prostate cancer.
  • Patients were assigned to either RARP or LRP, with all procedures performed by a single surgeon using identical techniques.
  • Outcomes including continence, potency, complications, and PSA levels were recorded and statistically analyzed.

Published on: August 19, 2025

Main Results:

  • No significant differences were observed in demographic, perioperative, or pathologic results between RARP and LRP groups.
  • Continence rates were significantly higher in the RARP group at 3 months (80% vs. 61.6%) and 1 year (95% vs. 83.3%).
  • Erectile function recovery was also superior in the RARP group (80% vs. 54.2%) for nerve-sparing procedures.

Conclusions:

  • RARP demonstrates superior functional outcomes, specifically in the recovery of urinary continence and erectile function.
  • The study suggests RARP may offer advantages over LRP for prostate cancer treatment.
  • Further research is recommended to validate these findings due to the study's limited sample size.
