Unintentional cystotomy is a known complication of the tension-free vaginal tape procedure and is commonly diagnosed intraoperatively. Delayed diagnosis does occur and various reparative techniques have been described, some requiring laparotomy with intentional cystotomy and repair. We report a case where a 46-year-old woman underwent vaginal reconstructive surgery including placement of a tension-free vaginal tape, which was complicated by unilateral cystotomy. A delayed diagnosis of intravesical tape placement was made requiring reoperation. The patient underwent a minimally invasive transvaginal procedure for removal and immediate replacement of the malpositioned arm of the tape. We conclude that a transvaginal approach may be an acceptable technique for revision and replacement of the tension-free vaginal tape where cystotomy is identified within 44 h after the initial procedure. With this technique, a more invasive surgery including laparotomy with cystotomy might successfully be avoided.
