Assessment of surgical technique and perioperative morbidity associated with extraperitoneal versus transperitoneal laparoscopic radical prostatectomy.

Objectives: To compare the perioperative morbidity and surgical technique of the two main variants of laparoscopic radical prostatectomy: the more often used transperitoneal approach with primary dissection of the plane posterior to the seminal vesicles (TP-LRP) and a purely extraperitoneal approach (EP-LRP).

Methods: Our initial 20 consecutive patients who underwent EP-LRP and the last 20 consecutive patients who underwent TP-LRP were included in this retrospective study. The two groups were well matched for age, American Society of Anesthesiologists score, body mass index, prostate-specific antigen level, and Gleason score.
