A 72-year-old woman presented with lower urinary tract symptoms (incomplete voiding, voiding pain, and gross hematuria) 2 years after a tension-free vaginal tape (TVT) procedure for stress urinary incontinence. Cystoscopy revealed erosion of the urethra associated with a urethral stone attached to a polypropylene mesh. We performed transurethral resection of the polypropylene mesh and transurethral lithotripsy. After removal of the mesh, she had stress urinary incontinence but her symptoms resolved. Urethral erosion is a rare complication of TVT, and the method of handling the intrusive mesh has not been standardized. Transurethral endoscopic resection of the eroding mesh is a minimally invasive and successful procedure that should be considered for the treatment of this complication resulting from TVT.
