Acquired Rectourethral Fistula: Methods of Repair

Abstract

Rectourethral fistulas are a rare but devastating complication of urinary or rectal surgery, trauma or inflammation. Historically repair has posed a challenge because of technical difficulties and the high incidence of recurrent fistulas. We report 7 cases of acquired rectourethral fistulas of varying etiology (3 after prostatectomy, 3 after trauma and 1 after recurrent perineal abscess), which were managed by various means. Our data and those in the literature suggest that the first attempt at repair is the best and subsequent repairs become increasingly difficult; the York Mason approach allows easy accessibility with minimal risk of complications and the best chance for a functionally successful outcome when a vascularized flap is not required, and some cases may have such a low probability of successful resolution of the fistula as well as maintenance of urinary continence that cystectomy and supravesical diversion are appropriate considerations.
