Plain-English summary
Pyometra is a serious condition that affects female dogs who have not been spayed, where pus builds up in the uterus. The exact cause isn't fully understood, but it seems to be related to hormonal changes in the body, particularly involving estrogen and progesterone. This paper discusses the signs to look for, factors that increase the risk of developing pyometra, how common it is, and the different treatment options available, including both medical and surgical approaches. It also covers what the chances are for recovery and how it might affect a dog's ability to have puppies in the future. Overall, the treatments for pyometra can be effective, but the specifics depend on the individual case.
Abstract
Pyometra, literally meaning pus in the uterus, is a common disease entity of intact bitches. Similar conditions occur, including hydrometra and mucometra [De Bosschere H, Ducatelle R, Vermeirsch H, Van Den Broeck W, Coryn M. Cystic endometrial hyperplasia-pyometra complex in the bitch: should the two entities be disconnected? Theriogenology 2001;55:1509-19]. The exact etiology is unknown; however the repeated and prolonged response to estrogen followed by long intervals of progesterone dominance in the intact bitch leads to hormonally mediated changes in the endometrium. The endometrium changes when impacted by bacterial infiltration; changes in endometrial steroid receptors can result in the clinical syndrome described as pyometra. This paper will describe the signalment, risk factors, prevalence, proposed etiologic events, and both medical and surgical therapies. In addition, the prognosis for successful outcome and effects on future reproduction will also be described.
