Abstract
in English, French

A case of a developmental cloacal anomaly is described in a 5-month-old male puppy. The animal had a unique combination of anomalies: confluence of the urethra and rectum into a common tract with a single perineal opening, atresia ani, and 3 genital anomalies, namely, a perineal hypospadias, penile hypoplasia with ventroflexural curvature, and a scrotal cleft. Surgical correction was successful, with fecal continence maintained and no urinary tract infections occurring during long-term follow-up.

Malformation cloacale chez un chiot mâle âgé de cinq mois. Un cas de développement cloacal anormal est décrit chez un chiot mâle âgé de cinq mois. L’animal avait une combinaison unique d’anomalies : une confluence de l’urètre et du rectum dans un tractus commun avec une ouverture périnéale unique, une atrésie de l’anus, et trois anomalies génitales, à savoir, un hypospadias périnéal, une hypoplasie pénienne avec courbure ventroflexurale, et une fissure scrotale. La correction chirurgicale fut une réussite, avec la continence fécale maintenue et aucune infection du tractus urinaire se produisant durant le suivi à long terme.(Traduit par Dr Serge Messier).

Note the imperforate anus (*), a common wide perineal tract where the rectum and urethra converge into a cloacal opening (black arrow), and a raphe of skin that extends from the anal dimple to the fistula (white arrow). B — The pelvic region shows a penis with preputial aplasia and hypospadias. Note the moderate ventroflexural curvature of the penis and the divided scrotum, a bifid scrotum or scrotal cleft (*).
