Clinical and epidemiological characteristics of dogs with pyometra

The aim of research is to study the clinical and epidemiological features of dogs with pyometra. The practical part of the work was carried out at the AlisaVet veterinary clinic and the International Center for Reproduction and Animal Health Kovcheg LLC from September 2020 to May 2024. The diagnosis of pyometra was made comprehensively, based on the anamnesis, clinical and gynecological examination, transabdominal ultrasound (ultrasound) of the internal genital organs, ultrasound Dopplerography (USDG) of the uterine vessels and the results of a clinical blood test. When collecting complaints from owners about the health of pets, information was collected on their age, gender, breed, body weight, vaccination data, deworming, obstetric and gynecological history, duration and characteristics of the manifestation of the disease. During the clinical examination, the general condition of sick dogs was assessed, thermometry was performed, the rhythm and frequency of the pulse wave and the nature of breathing were examined. The external genitalia were also examined for the presence or absence (in the case of a closed form of the disease) of vaginal discharge. A clinical and epidemiological analysis of 54 cases of dogs with pyometra was conducted. To determine the characteristics of the blood flow (hemodynamics) of the uterus in pyometra, pulsed-wave Dopplerography of both uterine arteries was performed in 15 sick dogs with open and 10 with closed forms of the disease. The comparison group consisted of 10 healthy dogs in the diestrus stage. Hemodynamic indices (peak systolic (PSV) and peak diastolic (EDV) blood flow velocities, resistance indices (RI), systolic-diastolic ratio (S/D) were measured. In the comprehensive diagnosis of pyometra, the results of laboratory studies (general clinical (morphological) and biochemical blood composition) were also taken into account. This pathology was recorded in all climatic seasons of the year with a peak in winter (38.88 %). The bulk of the contingent of patients with pyometra were iparous bitches of small breeds (with a live weight of up to 10 kg) in the age range of 4-12 years. The average age of dogs with pyometra was (8.07 ± 3.61) years.
