Inadvertent iatrogenic prostatectomy and urethrectomy in 2 dogs.

Two dogs were referred because of dysuria following inadvertent iatrogenic total prostatectomy and urethrectomy. In both cases an existing perineal hernia was not recognized by the referring veterinarians and the caudally herniated prostate gland was diagnosed as a perianal neoplasia and subsequently removed. Both dogs were treated with isolation of the urinary bladder from the urethra and a permanent prepubic cystostomy tube.
