Hematocolpos, pyocolpos, and pyocolpometra in intact female dogs with imperforate hymen

Abstract

Accumulations of fluid or blood with or without purulent material in the vagina or uterus are termed hydro/ hemato/pyo-colpos/colpometra. These disorders can occur in animals as well as human patients with a persistent hymen or acquired stenosis of the vagina. The hymen is formed by fusion of the Müllerian ducts and urogenital sinus, and usually regresses during the fetal or neonatal period in domestic animals (Sadler, 1985). Congenital vaginal obstructive disorders have been rarely reported in dogs and treatment options with surgical correction or laser ablation have been published (
