Urethral prolapse in a dog of the American Bully breed

Abstract

Urethral prolapse, which is uncommon in dogs, is characterized by protrusion of the urethral mucosa beyond the tip of the penis and the external orifice of the urethra. It can occur due to congenital or acquired causes, with a higher incidence in young animals not castrated. The present study aims to report a case of urethral prolapse in a non-castrated dog of 2 years old (American Bully Terrier), which was treated at the Estácio de Sá University located in Rio de Janeiro city, with a history of excessive penis licking, dysuria, prepucial bleeding, and protrusion of the urethral mucosa after an attempt of copulation. During the physical evaluation, the animal presented all clinical parameters within the normal range; however, it showed excessive agitation and pain in the affected region. Then, the diagnosis was defined through direct inspection of the visualization of the protruding urethral mucosa. Given the animal's clinical and physical condition, the surgical procedure of resection and anastomosis of the prolapsed urethral portion was adopted. Therefore, it is concluded that this surgical technique proved to be effective since the patient presented excellent recovery and urethral healing, without any signs of post-surgical complications.
