Pedicled vastus lateralis musculofascial flap as a new technique for repairing rectourethral fistula after radical prostatectomy.

Abstract

We present a case of successful operative management of an iatrogenic rectourethral fistula with a pedicled vastus lateralis musculofascial flap. The fistula was created during radical prostatectomy operation. During the operation, it was deemed possible to spare this patient from a diverting colostomy and primarily repair a rectal injury. Postoperatively, however, a rectourethral fistula occurred, which was confirmed on retrograde urethrogram. A first attempt failed to close the fistula utilizing the transanal rectal flap advancement technique. A novel technique was attempted using a pedicled vastus lateralis musculofascial flap. This is the first report to our knowledge of repairing a rectourethral fistula with a pedicled vastus lateralis musculofascial flap.
