A prospective trial comparing consecutive series of open retropubic and robot-assisted laparoscopic radical prostatectomy in a centre with a limited caseload.

OBJECTIVE: To compare perioperative, oncologic, and functional outcomes from two consecutive series of patients with localised prostate cancer treated by retropubic radical prostatectomy (RRP) or recently established RALP in our hospital, which has a limited caseload. DESIGN, SETTING, AND PARTICIPANTS: One hundred fifty consecutive patients were enrolled. Their data and outcomes were collected and extensively evaluated. INTERVENTION: Seventy-five consecutive patients underwent RRP, and 75 consecutive patients underwent RALP, including all patients of the learning curve. MEASUREMENTS: Patient baseline characteristics, perioperative and postoperative outcomes, and complications were evaluated. End points were oncologic data (positive margins, prostate-specific antigen [PSA]), perioperative complications, urinary continence, and erectile function at 3- and 12-mo follow-up. RESULTS AND LIMITATIONS: The preoperative parameters from the two groups were comparable. The positive surgical margin (PSM) rates were 32% for RRP and 16% for RALP (p=0.002). For RRP and RALP, the PSA value was
