As use of the tension-free vaginal tape (TVT) grows, more unexpected findings during this procedure are likely to be encountered. However, concomitant resection of a bladder tumor during the TVT procedure is rare. A TVT operation was carried out in a 56-year-old woman with urodynamic stress incontinence. A bladder tumor located in the trigone was found incidentally during cystoscopy. Concomitant resection of the bladder tumor was performed following the TVT procedure. The surgical result of our patient suggests that concomitant resection of a benign intravesical pathology with TVT procedure is safe and effective. Moreover, it does not compromise overall improvement of stress incontinence. The value of cystoscopy during the TVT procedure is emphasized.
