NRS: self-reported 11 points (0–10) numeric rating scale prior to surgery (during the preoperative evaluation period) and at six-months follow-up.

Nonresponders: NRS changed by less than 3 points. Paradoxical response: NRS ↑ by 3 points or more. “de novo” dyspareunia: NRS prior to surgery = 0 and NRS ↑ by 3 points or more. Dysp: deep dyspareunia. Dysm: dysmenorrhea (Ø means not assessed—hormone blockade). PPain: nonmenstrual pelvic pain. NM: nonmenstrual (acyclic). Length of nonmenstrual pelvic pain (in months). Pelvic surgery in the past includes VagHTM: vaginal hysterectomy, Opt: oophoroplasty, Otm: oophorectomy, SubHTM: subtotal hysterectomy, End: endometriosis, A: Arthrodesis (spinal fusion)].

Mental disorders according the International Classification of Diseases published by the World Health Organization; diagnosis was established by a psychologist and/or a psychiatrist. Case 5 was not assessed by a psychologist. The pain disorder of the case 19 includes fibromyalgia. Case 21’s eating disorder is binge eating. Indications of surgery inlcudes P: pain, I: infertility issues. Hormone use (those used in the last 3 months) includes COC: combined estrogen-progestin oral contraceptives (cCOC: continuous). VR: combined estrogen-progestin vaginal ring. IUD: progestin intrauterine device. Goserelin: 10.8 mg goserelin acetate implant (number of injections after surgery). Cases 12 and 22 were the only who underwent long-term postoperative physical therapy as a complementary treatment (the positive outcomes subsequent to the six-month follow-up were not included in this study). No patient required bladder catheterization for more than 2 weeks.
