Anatomical and Functional Outcomes of Posterior Intravaginal Slingplasty for the Treatment of Vaginal Vault or Uterine Prolapse: A Prospective, Multicenter Study

PURPOSE: We aimed to evaluate the anatomical and functional outcomes of posterior intravaginal slingplasty (P-IVS) for the treatment of a vaginal vault or uterine prolapse (VP/UP). MATERIALS AND METHODS: This was a 12-month prospective, multicenter, observational study. Women aged over 30 years who presented with stage II or greater VP/UP underwent P-IVS by four urologists at four university hospitals. Preoperatively, pelvic examination by use of the Pelvic Organ Prolapse Quantification (POP-Q) system, the Pelvic Floor Distress Inventory (PFDI) questionnaire, the 3-day frequency volume chart, and uroflowmetry were completed. At the 12-month follow-up, changes in the POP-Q, PFDI, frequency volume chart, and uroflowmetry parameters were assessed. Cure was defined as VP/UP stage 0 and improvement as stage I. RESULTS: The cure and improvement rates among the 32 women were 65.6% and 34.4%, respectively. All subscale scores of the Urinary Distress Inventory, the general subscale score of the Pelvic Organ Prolapse Distress Inventory, and the rectal prolapse subscale score of the Colo-Rectal-Anal Distress Inventory were significantly improved. There were no significant changes in the frequency volume chart or uroflowmetry parameters. There was one case of surgery-related transfusion. CONCLUSIONS: Trans-vaginal repair by P-IVS is an effective and safe procedure for restoring the anatomical defect and improving the associated pelvic floor symptoms in women with VP/UP.
