BACKGROUND AND PURPOSE: A large prostate can complicate an extraperitoneal robot-assisted radical prostatectomy (RARP). We report our experience with RARP and evaluate the effects of prostate size on treatment outcomes after extraperitoneal RARP. PATIENTS AND METHODS: Information on 355 consecutive patients undergoing extraperitoneal RARP was gathered, and patients with prostate weight <75 g (N = 319) were compared with those having glands >or=75 g (N = 36). The factors considered were age, body mass index, total operating time, estimated blood loss, serum prostate specific antigen (PSA) concentration, pathologic stage and Gleason grade, intraoperative and peri-operative complications, margin status, and continence. RESULTS: A statistically significant difference (P < 0.05) was noted in age (59 v 64 years), PSA concentration (6.07 v 8.9 ng/dL), and blood loss (175 v 226 mL) between patients with smaller v larger prostates. No difference was seen in Gleason score (6 v 6), clinical T stage, operative time (217 v 225 minutes), or total positive-margin rate (13% v 19%). A higher positive-margin rate was seen in patients with stage T(3) disease and larger prostates. The 6-month continence rate in patients with a prostate volume < 75 g was 97% v 84% in patients with larger prostate volumes ( P < 0.05). CONCLUSION: Although a large prostate volume is associated with a slight increase in short-term urinary complications postoperatively, it should not be considered a contraindication for the experienced surgeon. This higher risk raises the question of a possible need for longer catheterization in this subset of patients.
