The effect of sacrospinous ligament fixation during vaginal hysterectomy on postoperative de novo stress incontinence occurrence: a prospective study with 2-year follow-up

Abstract

Background/aim: To investigate the risk of de novo stress urinary incontinence SUI occurrence in women who were treated for pelvic organ prolapse POP with sacrospinous ligament fixation SSLF in addition to vaginal hysterectomy VAH and antero-posterior colporrhaphy CAP over a 24-month follow-up period. Materials and methods: A prospective randomized study was designed. Women without occult or obvious SUI were randomized into either one of the study groups: Group 1: VAH + CAP, and Group 2: VAH + CAP + SSLF. Postoperatively, the patients were reevaluated for de novo SUI occurrence. Results: A total of 150 women were analyzed [G1 = VAH + CAP n: 77 and G2 = VAH + CAP + SSLF n: 73 ]. Mean age, parity, body mass index, menopausal status, and preoperative POP degree, grade 1 and grade 2-3 cystocele and rectocele frequencies were similar between the 2 groups. During follow-up period, de novo SUI developed in 7 patients 9.1% of Group 1, and in 6 patients 8.2% of Group 2 P > 0.05 . In Groups 1 and 2, POP recurrence occurred in 5 6.4% vs. 1 1.3% cases,respectively P
