Traumatic urethral rupture is uncommon in cats but may occur secondary to high energy trauma and can cause severe systemic compromise. An 8-month-old neutered male cat presented after trauma by hit-by-car, and retrograde urethrography confirmed a pelvic urethral rupture. Despite conservative management, urethral stricture subsequently developed. Surgical correction was performed by resection of the stenotic segment and urethral anastomosis via a pubic osteotomy approach. The cat recovered normal urination without complications, and no recurrence was observed during one year of follow-up. This case demonstrates successful surgical repair of post-traumatic urethral rupture and stricture in a cat using a pelvic osteotomy approach.
