Pyometra is an accumulation of purulent material within the uterus and one of the most frequent geriatric diseases in non-spayed female dogs.


Present study was conducted to survey for relevance between pyometra and relevant factor such as breed, age, and presence of tumors in dogs.


Records of 42 cases of pyometra in dogs presented to the Department of Surgery, Animal Medical Center, Chonbuk National University from 2012 to 2014, were evaluated.


Pyometra were classified into three types such as closed, open and stump and the incidence ratio were 55% (n = 23), 38% (n = 16), and 7% (n = 3), respectively. The mean age is 9.4 ± 3.7 year-old and more than half of cases (n = 25) were geriatric patients (> 10 years). Based on diagnostic imaging, the intercurrent tumors were revealed in 21 cases (50%) and within tumor-intercurrent cases, 4 cases showed multiple region of tumors. Most affected sites were mammary (n = 7) and uterine (n = 7) and spleen, liver, perineal, ovary and inguinal tumors followed in order. Within mammary tumors, adenoma, carcinoma and adenocarcinoma were diagnosed on histopathological examination. Most frequent breeds were mixed (n = 8) and Maltese (n = 7) while there were not significant breed differences in the present study.


The present study described relevance between pyometra and other clinical factors. Pyometra more frequently occurred in geriatric patients and concurrent tumors should be assessed in canine pyometra patients.


This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (NRF-2014R1A2A2A01007969).
