Pyometra
Also known as: Infected uterus
Pyometra is a life-threatening bacterial infection of the uterus that develops in intact females, usually within weeks of a heat cycle under the influence of progesterone. Pus accumulates within the uterus, and toxins released into the bloodstream can cause sepsis, kidney injury, and death. It is classified as open (cervix open, discharge visible) or closed (cervix shut, no discharge), with the closed form being more dangerous. Emergency surgical removal of the uterus and ovaries is the treatment of choice.
