Pyometra is a bacterial infection of the uterus. The uterine lining gets thick, and then infected by bacteria and filled with pus. Bacteria from the uterus can leak into the blood and abdomen, causing shock and death.
Pyometra is a life-threatening condition that requires quick and aggressive treatment.
Pyometra most commonly occurs in older, non-spayed, females following a heat cycle.
With every heat cycle, the uterine walls thicken, preparing for pregnancy. If pregnancy does not occur after a few cycles, the following will cause infection:
During a heat cycle, white blood cells cannot enter the uterus. Therefore, when the bacteria grow, there is nothing to stop it.
Another cause can be reproductive medications thatmay contain hormones that cause the uterine wall to thicken. If your cat is not spayed, and is on reproductive medicine, your veterinarian should monitor her.
Signs depend if her cervix (the opening to the uterus) is open or closed.
Foul-smelling vaginal discharge (blood, pus or mucus) is the first sign of an infected uterus. You may see this discharge on your cat’s skin, on the hair below the tail, or anywhereshe has lain. These cats seem less sick because the infection is able to leave the body.
Keep in mind: many cats clean themselves of vaginal discharge before the owner sees it.
There will be no vaginal discharge. Rather, the infection leaks into the bloodstream and abdomen, leading to shock and death. These cats will be sicker than those with an open cervix because the infection stays in their body.
Common signs with a closed cervix:
If you do not have your cat spayed, and she displays any of the above signs, go to your veterinarian right away. Pyometra is fatal without immediate treatment.
To diagnose your pcat with pyometra, your veterinarian may perform the following:
Pyometra is life threatening, and needs aggressive treatment. The best treatment is an emergency spaying surgery, which is complicated because the infected contents of the uterus can spill.
The emergency spaying surgery includes:
With an open cervix, and if the owner insists on preserving the animal’s reproductive capability, your veterinarian may try treating the pyometra with hormone injections. These cause the uterus to contract and expel the pus.
This treatment is dangerous because the contracting uterus can rip and spill puss. Its success rate is lower and leaves room for a relapse. Also, your cat will not improve for about forty-eight hours, so it is not an option for severely ill cats.
Side effects last for a few hours after each injection, and become milder with each treatment:
Spaying your pet is a simple way to prevent pyometra. Otherwise, your pet will eventually contract pyometra.
The importance of spaying cannot be stressed enough. A female pet will benefit from spaying at any age, but it’s best to have your pet spayed at the youngest age possible
Most pets will recover successfully with immediate surgery. However, if treatment is not performed promptly, pyometra is fatal because of the toxic effects of the pus.
