Risk factors for surgical failure after posterior intravaginal slingplasty: a case series

Objective

The goal of this study was to analyze the potential risk factors of surgical failure after posterior intravaginal slingplasty for uterine or vaginal vault prolapse.

Study design

Women with symptomatic uterine or vaginal vault prolapse that extended to or beyond the introitus were eligible for inclusion. Each woman underwent a detailed history taking and a vaginal examination for staging of pelvic organ prolapse before treatment. Follow-up evaluations were at 3, 6, 9, 12, 18, 24, and 30 months after the operation. Surgical failure is defined as the presence of symptomatic uterine or vaginal vault prolapse ≧stage 2 (higher than 0, at the hymen) after posterior intravaginal slingplasty.

Results

The surgical failure rate (8/61) following posterior intravaginal slingplasty was 13.1%. Using univariable logistic regression, C or D point stage IV before surgery was significantly associated with surgical failure of posterior intravaginal slingplasty for uterine or vaginal vault prolapse. Complications (11/61 = 18%) included vaginal erosion (9.8%), blood loss over 500 ml (4.9%), and perineal pain (3.3%).

Conclusion

Procidentia is a significant risk factor for surgical failure of posterior intravaginal slingplasty, and therefore this procedure should never be used alone in patients with complete uterine or vaginal vault prolapse.
