Assessment of some endogenous factors influence on urolithiasis incidence in dogs and cats in the city of Abakan

The aim of the study is to analyze the prevalence of urolithiasis in dogs and cats in Abakan in 2021-2023 and to assess the influence of some endogenous factors on the possibility of urolithiasis formation. In order to identify the incidence of urolithiasis in dogs and cats in Abakan, comprehensive retrospective and prospective studies were carried out using primary documents (outpatient journals, outpatient cards, patient medical histories) of veterinary institutions (clinics, offices, points, animal disease control stations) in Abakan, Republic of Khakassia, for the period from 01/01/2021 to 12/31/2023. The total number of outpatients admitted during the reporting period, the number of patients with urinary tract pathologies, including the number of animals with newly diagnosed urolithiasis, were assessed. The species, age, sex, size and condition of the animal were taken into account. A comprehensive examination of 9,074 cats and 7,433 dogs living in the city of Abakan was conducted. During the specified period, 359 cats and 208 dogs with urolithiasis were identified. It was found that the incidence of urinary tract pathologies is 34.15% in cats and 17.65 % in dogs. Urolithiasis accounts for 11.58 % of cases in cats and 15.86 % of cases in dogs. The main endogenous factors influencing the occurrence of urolithiasis in dogs and cats are age (urolithiasis was more common among groups of dogs and cats of reproductive age), gender (urolithiasis was more often recorded in neutered male dogs and cats), early castration (only in male cats), excess weight, and belonging to a small size group (only in dogs).
