Results and complications of tension-free vaginal tape (TVT) for surgical treatment of female stress urinary incontinence.

Thirty-one patients with stress urinary incontinence were operated on using tension-free vaginal tape (TVT). All were evaluated preoperatively with urodynamics, pad test and stress test. Conservative treatment was without significant effect. Three months after the operation no patients had stress incontinence but I with mixed incontinence experienced deterioration of her urge incontinence and 2 experienced de novo urge incontinence. The de novo urge incontinence was significantly improved and the urodynamic investigation normal after approximately 5 months. One patient with a previous operation with Kelly sutures under the urethra developed a urethrovaginal fistula. Fifteen patients were observed for 1 year. One patient who was continent after 3 months developed slight stress incontinence.
