Management of Erosion of Graft Materials in Pelvic Floor Reconstruction

We present an overview of the current literature and management techniques for vaginal extrusion or urinary tract erosion of graft materials used in pelvic floor reconstruction. A MEDLINE search was performed to identify literature pertaining to the incidence and management of vaginal or urinary tract exposure of graft materials commonly used in anti-incontinence and pelvic floor reconstructive procedures. Dependent on the type of mesh material used, a vaginal extrusion rate of up to 77% has been reported. The currently accepted, loosely woven, monofilament type I polypropylene meshes appear to have acceptable lower exposure rates in the range of 1-3% for slings, but with the larger area of mesh used in prolapse repairs, the rate increases to up to 10%. With the current widespread use of graft materials to reinforce pelvic floor reconstructive techniques, it is imperative for surgeons to be familiar with potential complications related to the materials and proper management of these complications. Although it is beginning to appear that the benefit of using some synthetic materials may outweigh the risks, proper management and understanding of the risks is important in order to counsel our patients appropriately and responsibly prior to their surgeries.
