Surgical correction of rectoprostatic fistula.

A rectoprostatic fistula is a rare complication of prostatic operations, and the literature on the subject is scanty. Three men were treated for rectoprostatic fistulas representing complications of prostatic surgery. Mason's transsphincteric transrectal operation resulted in prompt, primary healing of the fistula. Subsequent colostomy closure left all 3 patients with normal urinary and fecal control. A systematic three-step sequence of operation is advocated for the treatment of rectoprostatic fistulas. The Mason technique provides excellent exposure and reliable closure of rectourinary fistulas.
