Anterior and middle pelvic organ prolapse repair using a six tension-free strap low weight transvaginal mesh: long-term retrospective monocentric study of 311 patients.

INTRODUCTION

Treatment of pelvic organ prolapse is an important public health issue due to the ageing population. The Food and Drug Administration, in 2011, issued a warning on complications after transvaginal insertion of high weight mesh. We evaluated a 6 tension-free straps, light prosthesis made from polypropylene monofilaments.

MATERIALS AND

METHODS

This monocentric, retrospective study included patients undergoing anterior or apical prolapse repair surgery by placement of a six tension-free strap low weight vaginal mesh between 2008 and 2017. The surgical history, concomitant surgery, clinical examination results, pre and postoperative results of the Urinary Symptom Profile questionnaire, and intraoperative and postoperative complications were collected from patients' medical records.

RESULTS

311 patients were included (median follow-up: 33 months). The majority (93%) had stage ≥ III cystocele and 26% had stage ≥ III hysterocele. Postoperatively, there were nine cases (2.9%) of asymptomatic cystocele recurrence and 11 (3.5%) cases of hysterocele recurrence, among them six underwent reoperation. Vaginal comfort was significantly improved in 92% vs. 17% before surgery (p < 0,0001); two (1,76%) patients had de novo dyspareunia. Preoperatively, 104 patients had stress urinary incontinence (SUI), 45,2% of them were cured postoperatively. There were 62 (30%) cases of de novo SUI. A significant improvement of dysuria (p < 0,0001) and overactive bladder (OAB) was found for all severity stages (p < 0,0001). Severe complications included haematoma (7,4%), mesh exposure (1.3%), retraction (0.6%), bladder injury (0.6%) and chronic pain (0.6%).

CONCLUSION

Treatment of anterior and/or mid-segment prolapse by transvaginal insertion of a six-strap low-weight mesh is long-term effective, with acceptable morbidity.
