The incidence of mesh extrusion after vaginal incontinence and pelvic floor prolapse surgery

Abstract

Purpose: The advantages of using synthetic mesh in vaginal reconstructive surgery are significant. However, the concern about extrusion has led many to question its use. We wished to learn the extrusion rates and time to extrusion in patients undergoing vaginal stress incontinence and prolapse surgeries using polypropylene mesh.

Materials and methods: Five hundred and seventy six women underwent vaginal reconstructive surgery with synthetic mesh between August 2000 and October 2009 for the treatment of stress urinary incontinence, with or without pelvic organ prolapse repair. 367 patients had at least one year follow-up. Procedures were: pubo-vaginal sling (PVS), PVS and anterior repair, PVS with anterior and/or posterior repairs, and PVS with hysterectomy and anterior and posterior repairs. Time to mesh extrusion was estimated using a survival function curve.

Results: Forty-two (11.4%) patients sustained a mesh extrusion. The rate of mesh extrusion was (6.3%) in the PVS group, (14.7%) in the PVS and anterior repair group, (11.1%) in the PVS with anterior and posterior repairs group and (5%) in the PVS with hysterectomy and anterior and posterior repair. Percent extrusion free at one to four years post-op was (91%) and (85%).

Conclusion: Our study provides a large series of prolapse cases performed by a single surgeon with follow-up that
extends at least one year, with the longest follow-up at eight years. The incidence of long term mesh extrusion needs to be considered with respect to the support advantages of synthetic mesh in planning vaginal reconstructive surgery.
