The transobturator tape method is a newer surgical technique for the treatment of stress urinary incontinence. Limited data exist related to complications with this approach or the types of mesh products used. We report our experience with vaginal erosions associated with the Mentor ObTape™ and American Medical Systems Monarc™ transobturator slings.

Materials and Methods

Beginning in December 2003 selected female patients with anatomic urinary incontinence were prospectively followed after placement of the Mentor ObTape™. Beginning in January 2004 we also began using the American Medical Systems Monarc™ in similar patients. Patients were admitted overnight after surgery, discharged on oral antibiotics, and seen in the clinic at 6 weeks postoperatively.


A total of 67 patients have undergone placement of the Mentor ObTape™ and 9 of those patients (13.4%) have had vaginal extrusions of the sling. Eight patients reported a history of persistent vaginal discharge. One patient presented initially to an outside facility with a left thigh abscess tracking to the left inguinal incision site. Each patient was taken back to the operating room for mesh removal. A total of 56 patients have undergone placement of the AMS Monarc™ and none have had any vaginal erosions.


Our high rate of vaginal extrusion using the ObTape™ has led us to discontinue the use of this product in our institution. Continued followup of all of these patients will be of critical importance.
