Abstract

A five-year-old, castrated male, Pung-san dog was referred to Konkuk University Veterinary Teaching Hospital with trauma and persistent hemorrhage in the inguinal region. The dog had a history of being wounded by a wild boar at 5 days prior to presentation. Rupture of the membranous urethra and urethrocutaneous fistula were demonstrated by the retrograde positive contrast urethrography. A urinary catheter was placed to identify the urethra and urethrocutaneous fistula. The necrotic tissues and damaged tissues by urine leakage around urethrocutaneous fistula were debrided. An urethral anastomosis over an indwelling catheter was performed. The dog maintained normal urination without other complications including dysuria and hematouria at the follow-up evaluation after 1 month postoperatively. A retrograde urethrogram repeated at 2 months after surgery showed no urethral stricture.
