Summary
This summary is machine-generated.

Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) demonstrates surgical safety and improves early continence. Patients with high-risk prostate cancer showed good oncological outcomes, though positive margins require patient counseling.

Area of Science:

  • Urology
  • Surgical Oncology
  • Robotic Surgery

Background:

  • Robot-assisted radical prostatectomy (RARP) is a standard treatment for prostate cancer.
  • The Retzius-sparing (RS) approach aims to preserve neurovascular structures and improve functional outcomes.
  • Limited data exists on the initial experience and outcomes of the RS-RARP technique.

Purpose of the Study:

  • To describe the standardized technique of Retzius-sparing robot-assisted radical prostatectomy (RS-RARP).
  • To evaluate the initial oncological and functional outcomes of RS-RARP in a single center.
  • To assess the reproducibility and safety of the RS-RARP procedure.

Main Methods:

  • A step-by-step description of the RS-RARP technique, supplemented by video.
  • Evaluation of early oncological and functional results in 77 patients with a median follow-up of 11 months.
  • Inclusion of patients with local high-risk or locally advanced prostate cancer.

Main Results:

  • No intra-operative complications; 2.6% high-grade complications related to pelvic lymph node dissection.
  • Median operation time: 160 minutes; median hospital stay: 3 days.
  • One-year biochemical recurrence-free survival: 90.1%; 94.3% full continence after 1 year; 43.3% erectile function recovery.

Conclusions:

  • RS-RARP is a surgically safe procedure when performed with a standardized technique.
  • The technique demonstrates a beneficial effect on the early return of urinary continence.
  • Patients must be informed about the risk of positive surgical margins (42.9% in this series).
