However, pyometra is one of those pathologies that is frequently presented in the practice and is related to a large number of secondary complications, largely due to the migration of bacteria through the blood.
Generally, female cats during estrus show behavioral changes such as continuous rubbing of the face, neck or back, increased vocalizations and urination, as well as being more restless than usual.
Most cases of pyometra occur within two months after ovulation, when estrogens have been used previously as abortifacients or to prevent pregnancy, or after administration of progestogens to prevent estrus, but there are studies in which up to 22% of pyometra cases were not related to estrus in the previous 30-60 days.
How risky is pyometra surgery?
This operation is urgent, because if the womb is closed, it can burst at any moment inside the bitch and cause a peritonitis (abdominal infection) that is much more difficult to control.
What happens if pyometra is not operated?
If the disease progresses undetected and untreated, septicemia (bacteria in the blood), toxemia (toxins in the blood), renal failure and peritonitis may occur.
How is the pyometra operation performed?
– Surgical: this involves performing an ovariohysterectomy, i.e. removing the uterus and ovaries. Depending on the state in which the bitch is admitted to surgery, it will require subsequent hospitalization or not, to treat possible complications arising from the disease (renal failure, sepsis, anemia …).
Death due to canine pyometra
In this case there is no other alternative but to resort to surgery; here the recovery is complete because everything is removed and the infection disappears with what is removed. Treatment with medication is indicated when the animal is to be kept for reproduction, when the sanitary condition is not adequate to withstand an operation and also for economic reasons since surgery is more expensive.
Symptoms appear 3-6 weeks after estrus. They are very variable, but the most frequent are: apathy, anorexia (stop eating), fever (in 20% of cases), vomiting, polydipsia (drinking a lot), polyuria (urinating a lot) and dehydration. Sometimes, when the pyometra is “open”, a discharge of purulent discharge from the vagina is observed. Some bitches arrive in shock due to severe complications secondary to pyometra such as: septicemia (bacteria in the blood), endotoxemia (toxins in the blood), peritonitis or renal failure.
How long can a dog with pyometra last?
It can last up to 11 days and the bitch will attract males but will not allow mating. Estrous: at this stage the bitch allows the male to mount her and bleeding decreases. It can last up to 21 days but normally lasts 9 days. Ovulation also takes place here, normally 2 days after the beginning of estrus.
How long does pyometra surgery last?
It lasts about 60 days. The female rejects the male again, the vulva decreases in size and sometimes expels a mucous discharge through the vagina. The changes are caused by a predominance in the secretion of the hormone progesterone. During this phase the animal is susceptible to pyometra.
How is pyometra cured?
Treatment for canine pyometra
Once the disease is detected, the most common treatment used to cure canine pyometra is surgery. This surgical treatment consists of removing the ovaries and uterus. With this operation, your dog will not be able to become pregnant.
Pyometra after surgery
of them with open neck pyometra with sepsis, 5 with open neck without sepsis and 1 with closed neck without sepsis, which were attended at the Veterinary Hospital “Humberto Ramírez Daza” (HVHRD) of the Universidad Centroccidental “Lisandro Alvarado” (UCLA).
The results are consistent with those reported by Weiss, et al. (2004) and Gama and Russiano (2007), who found a higher percentage of open-neck pyometra than left ventricular pyometra (left ventricular blocks).

Why does pyometra happen?
Pyometra is caused by an acute or chronic alteration of the endometrium – walls that cover the uterus – and appears during the luteal phase due to a colonization of the uterus by opportunistic bacteria from the bitch’s vaginal flora.
What medication is used for pyometra?
Surgery should be performed as soon as possible when the patient is stabilized by administration of saline and antibiotics. In animals of high reproductive value that have open type canine pyometra and are stable, a treatment based on antibiotics and prostaglandins can be used.
How to cure metritis in dogs?
The most effective recommendation and treatment for an infection in the womb is surgical resolution: i.e. Ovariohysterectomy. It consists of the surgical removal of the ovaries and uterus (womb). It is a major surgery and requires general anesthesia.
How much does a pyometra operation cost?
All patients who are being treated for pyometra should immediately begin empirical bactericidal antibiotic treatment. A good choice of antibiotics, based on the historical bacterial causes of uterine infection, is amoxicillin-clavulanate or a combination of a penicillin and a fluoroquinolone. The adequacy of empirical antibiotic treatment should then be confirmed by antibiotic susceptibility results, which are reported from the patient’s original bacterial cultures. Antibiotic therapy should be continued for 7 to 14 days after resolution of the patient’s pyometra, based on physical examination, laboratory and ultrasonographic findings.3,4
Regardless of cervical patency, ovariohysterectomy is the treatment of choice for bitches with pyometra, which owners do not consider to be of reproductive importance.4 The main advantage of ovariohysterectomy over medical management is that it is both curative and preventive of pyometra recurrence. A discussion of ovariohysterectomy is beyond the scope of this article and can be reviewed in any veterinary surgical text.
