Radical prostatectomy for prostatic adenocarcinoma: a matched comparison of open retropubic and robot‐assisted techniques

OBJECTIVE To assess the perioperative complications and early oncological results in a comparative study matching open radical retropubic (RRP) and robot‐assisted radical prostatectomy (RARP) groups. PATIENTS AND METHODS From August 2002 to December 2005 we identified 294 patients undergoing RARP for clinically localized prostate cancer. A comparison RRP group of 588 patients from the same period was matched 2:1 for surgical year, age, preoperative prostate‐specific antigen level, clinical stage and biopsy Gleason grade. Perioperative complications were compared. Patients completed a standardized quality‐of‐life questionnaire. Pathological features were assessed and Kaplan‐Meier estimates of biochemical progression‐free survival (PFS) were compared. RESULTS There was no significant difference in overall perioperative complications between the RARP and RRP groups (8.0% vs 4.8%, P = 0.064). Wound herniation was more common after RARP (1.0% vs none, P = 0.038), and development of bladder neck contracture was more common after RRP (1.2% vs 4.6%; P
