We aimed to replace an ileal segment in the place of posterior urethra using the anal sphincter as a continence mechanism. The experiment was carried on three male street dogs. In the first stage, only urethral replacement with an ileal segment was done and pulled through the anal sphincter in a male dog to see if anal sphincter would do any help for continence. A protruding stoma was created on the perineum. Perineal end of the ileal segment was sutured to the bulbous urethra in the other two male dogs to provide urethral patency in the second step of the operation. The dog in which the first operation was made gained continence on the 12th postoperative day. The other two male dogs, in which ileourethral anastomosis were made, became continent on the postoperative 12th and 15th days. No residual urine was found by catheterisation performed after urination. In controls, neither the stoma nor the anastomosis sites developed stenosis. This procedure may be applied in patients with complete incontinence who can not be corrected by any other surgical procedures, and a very good cosmetic result may be obtained.
