Utilising an ileal segment in the posterior urethral replacement procedures using anal sphincter to provide continence in dogs

We aimed to replace an ileal segment in the place of posterior urethra usin g the anal sphincter as a continence mechanism. The experiment was carried on three male street dogs. In the first stage, only urethral replacement wi th an ileal segment was done and pulled through the anal sphincter in a mal e dog to see if anal sphincter would do any help for continence. A protrudi ng 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 ureth ral 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 ot her two male dogs, in which ileourethral anastomosis were made, became cont inent on the postoperative 12th and 15th days. No residual urine was found by catheterisation performed after urination. In controls, neither the stom a nor the anastomosis sites developed stenosis. This procedure may be appli ed in patients with complete incontinence who can not be corrected by any o ther surgical procedures, and a very good cosmetic result may be obtained.
