Plain-English summary
Pyometra is a serious condition that affects female dogs, especially older ones that have never had puppies. It involves inflammation of the uterus, the buildup of pus inside it, and a bacterial infection. While a hormone called progesterone plays a big role in causing pyometra, recent research suggests that a condition called cystic endometrial hyperplasia (a thickening of the uterine lining) is not as closely linked to pyometra as previously thought. Instead, this study highlights the need for better terms to describe these conditions and their relationships. Overall, the findings aim to improve how veterinarians diagnose and understand pyometra in dogs.
Abstract
Pyometra is frequently diagnosed in female dogs, and it is characterized by endometrial inflammation, accumulationof purulent exudate within the lumen, and bacterial infection. In the dog, pyometra affects more often aged nulliparousbitches during the luteal phase. Pathogenesis of pyometra is multifactorial and progesterone seems to be a key factor. Cysticendometrial hyperplasia has been described as a predisposing condition for canine pyometra. However, a recent studydemonstrated that cystic endometrial hyperplasia is not significantly associated with naturally occurring pyometra, whereasthere is a significant association of this condition with pseudoplacentational endometrial hyperplasia. The aim of this reviewis to provide an update on canine pyometra, with focus on its association with uterine hyperplasic lesions, which supports aproposal for adoption of more adequate diagnostic terminology.
