Plain-English summary
A group of 405 female dogs diagnosed with pyometra (a serious infection of the uterus) underwent surgery to remove their uterus and ovaries. The good news is that 97% of these dogs survived the surgery and were able to go home, although some needed to stay in the hospital for a couple of nights. Dogs that had high levels of certain blood markers or a heart murmur were at a higher risk of complications. Overall, the surgery is effective and can be performed safely in regular veterinary clinics, allowing more dogs to get the help they need for this dangerous condition.

Abstract
OBJECTIVE: To determine the rate of survival to hospital discharge and identify indicators associated with poor outcomes among female dogs (bitches) with pyometra treated with ovariohysterectomy (OHE) in a nonspecialized setting. ANIMALS: 405 bitches diagnosed with pyometra at the American Society for the Prevention of Cruelty to Animals Animal Hospital from January 1, 2017, to February 8, 2019. PROCEDURES: For this retrospective study, medical records were searched and data collected including patient history, clinical signs, serum biochemical analyses results, and outcome (survival to hospital discharge, length of hospital stay, and uterine rupture). Logistic regression models were used to assess multivariable associations and identify potential predictive variables. RESULTS: The rate of survival to hospital discharge for bitches with pyometra treated with OHE was 97% (394/405); 44% (174/394) stayed in the hospital ≥ 2 nights, and 3% (11/390) had a ruptured uterus. Bitches with a high BUN concentration or heart murmur had greater odds of death after OHE; however, the model had low predictive power. Those with uterine rupture, inappetence, high concentrations of BUN or serum creatinine, low PCV, or dehydration had greater odds of hospitalization ≥ 2 nights. There were no significant predictors of uterine rupture. CLINICAL RELEVANCE: The rate of survival to hospital discharge was high for bitches with pyometra treated with OHE in a nonspecialized setting; therefore, general practitioners could expect similar outcomes. With this important procedure widely available in general practices, more pets can receive treatment for this life-threatening disease.
