    Abstract:
    BACKGROUND: Robotic-assisted laparoscopic radical prostatectomy (RALP) using the da Vinci surgical system (Intuitive Surgical, Sunnyvale, CA) is increasingly used for the management of localised prostate cancer. OBJECTIVE: We report the operative details and short-term oncological and functional outcome of the first 400 RALPs performed at our unit. DESIGN, SETTING AND PARTICIPANTS: From December 2003 to August 2006, 400 consecutive patients underwent RALP at our institution. A prospective database was established to record the relevant details of all RALP cases. SURGICAL PROCEDURE: A six port transperitoneal approach using a 4-arm da Vinci system was used to perform RALP. This database was reviewed to establish the operative details and oncological and functional outcome of all patients with a minimum of 12 months follow-up. MEASUREMENTS: Perioperative characteristics and outcomes are reported. Functional outcome was assessed using continence and erectile function questionnaires. Biochemical recurrence (prostate-specific antigen (PSA) > or =0.2 ng/mL) is used as a surrogate for cancer control. RESULTS AND LIMITATIONS: The mean age+/-standard deviation (SD) was 60.2+/-6 years. Median PSA level was 7.0 (interquartile range (IQR) 5.3-9.6) ng/mL. The mean operating time+/-SD was 186+/-49 mins. The complication rate was 15.75% comprising Clavien grade I-II and Clavien grade III complications in 10.5% and 5.25% of patients respectively. The overall positive surgical margin rate was 19.2% with T2 and T3 positive margin rates of 9.6% and 42.3% respectively. The biochemical recurrence-free survival was 86.6% at a median follow-up of 22 (IQR=15-30) months. At 12 months follow-up, 91.4% of patients were pad-free or used a security liner. Of those men previously potent (defined as Sexual Health Inventory for Men [SHIM] score > or =21) who underwent nerve-sparing RALP, 62% were potent at 12 months. CONCLUSIONS: The safety and feasibility of RALP has already been established. Our initial experience with this procedure shows promising short-term outcomes.
