Objective To investigate the clinical efficiency and surgical techniques of extraperitoneal laparoscopic radical prostatectomy (eLRP).Methods The clinical data of 18 patients with localized prostate cancer who underwent laparoscopic radical prostatectomy from March 2010 to March 2012 were analyzed retrospectively.Operating time,blood loss,blood transfusion rate,postoperative urinary continence rate and biochemical recurrence rate were monitored.Results The procedure was successfully operated in all patients without converting to open approach.Mean operating time was 205 min (ranged from 110 to 370 min).Mean blood loss was 325 ml (ranged from 200 to 600 ml).Postoperative urinary continence rates were 83.3.6％,88.9％ respectively at 3 months and 6 months after operation; the biochemical recurrence rate was 5.6％ at 6 months after the operation.One case (5.6％) appeared intraoperative rectal injury,1 case (5.6％) appeared postoperative urethral stricture.Conclusions Extraperitoneal approach laparoscopic radical prostatectomy is a safe and effective procedure for early localized prostate cancer.
