Erosion, defective healing and extrusion after tension-free urethropexy for the treatment of stress urinary incontinence.

A case-control study was performed in two departments performing tension-free urethropexy for the treatment of stress urinary incontinence. During a period of 4.5 years, 127 cases of tension-free vaginal tape operations (TVT) and 42 cases of intravaginal slingplasty (IVS) were performed. In the TVT group one case of urethral erosion was observed, but in the IVS group six cases of defective healing, erosion or extrusion were observed. It is considered that the complications might be due to the multifilamentous nature of the IVS tape in contrast to the monofilamentous nature of the TVT tape.
