Urethral erosion of tension-free vaginal tape presenting as recurrent stress urinary incontinence

The suburethral sling with tension-free vaginal tape (TVT) has become a popular treatment for stress urinary incontinence. Erosion of the mesh into the urethra is rare, usually presenting with hematuria, pain, voiding dysfunction or urge incontinence. A patient with stress incontinence was treated with a TVT suburethral sling. One month later, symptoms of recurrent stress incontinence developed. Cystourethroscopy revealed urethral mesh erosion. Surgical removal involved cystourethroscopic-assisted transurethral resection of the mesh, followed by vaginal dissection and periurethral withdrawal. Urethral mesh erosion should be considered in a patient who presents with atypical symptoms after being treated with a suburethral sling. It is important to obtain a detailed history and have a high clinical index of suspicion for erosion. Careful and comprehensive urethroscopy, in addition to cystoscopy, should be a mandatory part of the TVT procedure. Further study is needed to determine the optimal technique for mesh removal.
