Medical management of urethral and colonic perforation associated with urinary catheterization in a kitten.

A 6-week-old male kitten was evaluated because of stranguria and possible urethral blockage; a urinary catheter placed during general anesthesia penetrated the urethral and colonic walls and entered the colon. Treatment was conservative, with fluids administered i.v., administration of piperacillin, and supportive care. The kitten never became febrile or clinically ill and continued to thrive. There was no development of clinical signs consistent with stricture, diverticulum, or fistula formation. Complications from urethral perforation include infection and urethral stricture. Reconstructive surgery is considered the treatment of choice for traumatic urethral-colonic perforation. However, surgery may not be feasible or may be cost-prohibitive in certain situations. In such instances, medical management may provide a reasonable alternative to euthanasia.
