Plain-English summary
A 9-year-old female dog was taken to a veterinary hospital because she was having trouble urinating and defecating after having her ovaries and uterus removed. Doctors suspected a blockage in her vagina due to fluid buildup and tried surgery three times to fix the issue. They eventually performed another surgery to remove the entire lining of the vagina to prevent the problem from coming back, which worked well. Tests on the removed tissue showed it was a cyst from a leftover part of her developing urinary system. In this case, completely removing the cyst lining successfully treated the problem without harming the surrounding blood vessels and nerves.
Abstract
A 9-year-old female dog was referred to Azabu University Veterinary Teaching Hospital for dysuria and dyschezia after ovariohysterectomy. After a series of diagnostic imaging, vaginal obstruction was suspected by vaginal fluid retention. Surgical repair was attempted three times to establish patency through the vagina and the vestibule by episiotomy and laparotomy. Another laparotomy was performed to remove the entire vaginal mucosal layer to prevent recurrence, which resulted in favorable outcome. Histopathological examination revealed that the resected tissue was a cyst originated from mesonephric duct remnant. In the present case, the cyst was curable by the entire resection of the cyst lining membrane, which could eradicate all the secretory cells with least damage to the urethral vasculature and innervation.
