[Minimally invasive radical prostatectomy: Contribution of robotic support, functional and oncological outcomes]

Abstract

Objectives: Radical prostatectomy (RP) remains a standard for localized prostate cancer treatment. The objective of this study is to present this operating technique of the robot-assisted radical prostatectomy (PR-RA) and to evaluate oncological and functional results as well as on the surgical safety.

Methods: A first series of 1679 patients consecutively operated in our institution with this technique from 2005 to 2010 and with a 5-year follow-up evaluated in 2014. The oncology monitoring is ensured with a PSA test every six months during the first three years and once a year the years after if the level remains undetectable.

Results: The oncologic outcomes show 17.4% for pT2 stages and 36.9% for pT3 stages positive margins. The level of biological recurrence is 21.27% with an average delay of 88 months as the time needed for the recurrence to occur. At 12 months, urinary continence (0-1pad/day) returned at 94% of all patients and potency with successful penetration for all men is 61.1% and 88.8% for men with sexual activity before surgery.

Conclusions: The technique PRRA seems to be a reliable technique whose functional results studied from meta-analysis seem to be superior in terms of rapidity of recovery of the continence and erection in comparison with classical surgical or laparoscopic approach.
