How to do a transperineal rectovesical fistula repair with dartos flap interposition

Rectovesical fistula (RVF) is defined as an extra-anatomic communication between the rectum and bladder. A multitude of approaches and techniques have been described; however, there is a lack of consensus regarding which of these procedures is the optimal cost-effective, appropriate treatment to perform. We describe the repair of a persistent RVF via a transperineal approach, utilizing the dartos fascia flap, a technique with minimal description in the literature.
