Presacral neurectomy (PSN) is a surgical technique used to treat dysmenorrhea (menstrual cramps), chronic pelvic pain (CPP), and/or dyspareunia (pain with intercourse) in patients with severe, disabling symptoms that are refractory to standard therapies. The surgery is performed via laparoscopy or laparotomy as a primary procedure or in addition to resection of endometriosis lesions or pelvic adhesions. It involves the excision of the presacral nerve and its branches, with the goal of interrupting the uterine and cervical sensory nerve fibers and the transmission of pain signals.
