Prostatorectal fistula associated with tubular colorectal duplication.

Tubular colonic duplications are exceedingly rare. The authors present an unusual case of a boy with a persistent prostatorectal fistula resulting from a tubular colorectal duplication. The current case is unique for 2 reasons: (1) the presence of a fistula without any concomitant genitourinary anomalies and (2) the existence of a prostatorectal fistula.
