Use of a pedicled rectus abdominis muscle flap for repair of a failed vesicourethral anastomosis in a dog.

A 10-year-old mixed breed dog underwent a prostatectomy for an adenocarcinoma. Within three days the dog had signs of a uroperitoneum. Re-exploration revealed that a portion of the vesicourethral anastomosis had failed. Primary suturing of the tissue along the site of dehiscence following debridement of the devitalised tissue was impossible. A rectus abdominis muscle flap was created and successfully used to repair the site of leakage.
