Robot assisted radical prostatectomy: how I do it. Part I: Patient preparation and positioning.

Radical prostatectomy remains the standard treatment for long term cure of clinically localized prostate cancer, offering excellent oncologic outcomes, with cancer-specific survival approaching 95% at 15 years after surgery. The introduction of the "da Vinci Robotic Surgical System" (Intuitive Surgical, Sunnyvale, CA, USA) has been another important step toward a minimally invasive approach to radical prostatectomy. Technologic peculiarities, such as three-dimensional vision, wristed instrumentation with seven degrees of freedom of motion, lack of tremor, a 10x-magnification and a comfortable seated position for the surgeon has added value to the surgeon and patient. In this first part of a two article series, we describe preoperative patient preparation and positioning protocols for robot assisted radical prostatectomy (RARP) that are currently used in our institution (University of Montreal Hospital Center (CHUM)-Hopital St-Luc). We use the four-arm da Vinci Si Surgical System. Our experience with RARP is now over 250 cases with the senior surgeon having performed over 1200 RARPs and we have continually refined our technique to improve patient outcomes.
