Rectourethroperineal fistula in Crohn's disease.

We report the ninth case of a rectourethral fistula in Crohn's disease. The patient had undergone numerous surgical procedures for complications of severe ileocolitis before developing a rectourethroperineal fistula. His symptoms were confined to urine leaking from the perineal opening; the most common symptom of rectourethral fistula in Crohn's disease. He underwent surgical repair by an abdominoperineal approach and has been free of recurrence for a period of 2 years. The literature suggests that the incidence of rectourethral fistulae in patients with Crohn's disease is approximately 0.3% and that this complication comprises 6.2-11.1% of all genitourinary fistulae in Crohn's disease.
