Hydrocolpos in dogs: surgical treatment in two cases

Two young female dogs were diagnosed with hydrocolpos as a result of a congenital vaginal obstruction. In one dog, hydrocolpos had led to faecal tenesmus; in the other, the condition was an incidental finding during laparotomy. Diagnostic tests included vaginoscopy, ultrasonography and retrograde vagino-urethrocystography. In both dogs, the obstruction was located at the junction between the caudal vagina and the vaginal vestibule. Anastomosis of the caudal vagina and vestibule through an episiotomy was successful in both cases.
