Fistulae involving rectum and urethra: the place of Parks's operations.

Twenty-five rectovesical and rectourethral fistulae were treated over an 18-year period in which various methods for closing the rectal side of the fistula were developed, ultimately with two techniques using the full thickness of intestine. As a result of these operations the management of the urethral and vesical side of the fistulae became a relatively simple problem to which standard techniques could be applied.
