title: Comparison of laparoscopic presacral neurectomy and laparoscopic uterine nerve ablation for primary dysmenorrhea.
abstract: OBJECTIVE
  To compare laparoscopic presacral neurectomy and laparoscopic uterine nerve ablation for primary dysmenorrhea.
  
  
  METHODS
  Sixty-eight patients with primary dysmenorrhea and a poor response to medical treatment were randomized into two groups. One group (33 patients) had laparoscopic presacral neurectomy (LPSN) and the other group (35 patients), laparoscopic uterine nerve ablation (LUNA).
  
  
  RESULTS
  There were no complications, and all the patients left the hospital within 24 hours after surgery. The efficacy of both surgical methods was almost equal (87.9% vs. 82.9%) at the 3-month postoperative follow-up visit, but the efficacy of LPSN was significantly better than that of LUNA (81.8% vs 51.4%) at the 12-month visit.
  
  
  CONCLUSIONS
  LPSN is a valid option for treating primary dysmenorrhea.
