A case of a bitch with imperforate hymen and hydrocolpos.

ABSTRACT

A 38-month-old female Golden retriever was presented with dysuria and dyschezia. It was difficult to visualize the vagina by vaginoscopy due to a cystic polyp on the hymen. The polyp was 2 x 3 cm in diameter, round, and pink in color. From clinical and imaging evaluations the original diagnosis was mucometra or pyometra. From endoscopic examination of the vagina an imperforate hymen was finally diagnosed. The ovaries, uterus, and half of the vagina were removed through a median abdominal incision. The vagina contained about 1.5 liters of fluid, but the uterus and ovaries appeared normal. This is a rare case with imperforate hymen and hydrocolpos with a polyp on the hymenal membrane in bitch.
