Study Objective. To assess the effectiveness of laparoscopic uterine nerve ablation (LUNA) in women with dysmenorrhea caused by uterine myomas treated by laparoscopic bipolar coagulation of uterine vessels (LBCUV). Design. Prospective, randomized, longitudinal study (Canadian Task Force classification II-1). Setting. Private practice, university-affiliated hospital. Patients. Eighty-five women with uterine leiomyomas and associated dysmenorrhea. Intervention. Laparoscopic bipolar coagulation of uterine vessels with or without LUNA. Measurements and Main Results. Of 85 patients who entered the study, 41 were assigned to undergo LBCUV-LUNA (group A), which was successful in 40 (97.6%). In 44 women assigned to have LBCUV only (group B), 43 (97.7%) underwent successful surgery. Eighty women completed 1-, 3-, and 6-month follow-up (38 group A, 42 group B). The groups did not differ significantly in age, history of abdominopelvic surgery, intraperitoneal adhesions, endometriosis, concomitant surgery, and operating time. Seven (18.4%) of 38 women in group A and 12 (28.6%) of 42 in group B experienced lower abdominal pain postoperatively. Acceptable pain was defined as a score of zero or 1: 31 and 30 women in groups A and B reported scores of zero; 3 and 2 reported scores of 1; 4 and 8 reported scores of 2; zero and 2 reported scores of 3; and no patients reported scores of 4. The frequency and severity of postoperative pain were less in group A than in group B (both p
