title: Retrospective comparative study of 59 cases of laparoscopic radical prostatectomy: transperitoneal anterior versus transperitoneal posterior approach.
abstract: OBJECTIVE
  We retrospectively compared perioperative parameters, as well as the oncological and functional results, for laparoscopic radical prostatectomy (LRP) carried out via the posterior and anterior approaches in our hospital.
  
  
  METHODS
  We recorded pre-, peri-, and postoperative parameters and complications, and evaluated the oncological and functional results to compare the posterior approach (group 1, n = 25) with the anterior approach (group 2, n = 34).
  
  
  RESULTS
  There were no significant differences regarding the preoperative characteristics of the two groups. The incidence of major complications, positive surgical margins, and continence at 3 and 6 months postoperatively showed no significant differences between the two groups. Although mean blood loss (including urine) was not significantly different, the mean prostatectomy time was significantly shorter in group 2 (174.21 +/- 57.97 min) than in group 1 (224.76 +/- 66.72 min) (P = 0.003 by Student's t-test). Also, the postoperative recovery period until discharge was 5.94 days in group 2, and was significantly shorter than in group 1 (7.48 days) (P = 0.02 by Student's t-test).
  
  
  CONCLUSIONS
  This retrospective comparative study shows that the anterior approach yields similar, if not better results than the posterior approach for LRP.
