Urethral erosion of tension-free vaginal tape.

Tension-free vaginal tape (TVT) is gaining popularity as a treatment of choice for women with stress urinary incontinence. It is a minimally invasive procedure with reported short operative and postoperative hospitalization times and low complication rates. We describe urethral erosion of a TVT sling material in a 55-year-old woman who presented with immediate postoperative urinary retention. The sling material was surgically removed and the urethral defect repaired, with the patient continent at the 3-month follow-up visit. A mid-urethral synthetic sling such as the TVT can erode into the urethra.
