Complications associated with perineal urethrostomy in the cat.

Urethral obstruction is a common problem in male cats. The most prevalent location for the obstruction is the penile urethra. Most male cats with urethral obstruction can be effectively treated without surgery. However, some cats with this condition require a perineal urethrostomy. This surgical procedure involves removing the penile urethra and creating a permanent stoma between the skin and pelvic urethra. A variety of medical and management problems can develop early in the course of urethral obstruction. In addition, there are several potential intraoperative and postoperative complications related to the technique of perineal urethrostomy. Most medical problems and surgical complications respond to appropriate treatment.
