Introduction. It is believed that Urolithiasis men of working age are most often affected. However, recent studies have shown that the difference between the incidence of this disease among men and women is rapidly decreasing due to the increased incidence of urolithiasis in women. The purpose of the study: to determine the prevalence of urolithiasis among women over 45 years of age as part of screening study in the Republic of Chuvashia. Materials and methods. A population study of 658 women over 45 years of age was conducted on the basis of hospital № 1 in Cheboksary (Republic of Chuvashia) in 2021-2022. All participants underwent ultrasound examination of the urinary system organs to detect urinary stones. The diagnosis was confirmed by CT of the abdominal cavity and retroperitoneal space. Statistical data processing was carried out using the Statistics 10,0 program and Microsoft Excel. Results. Of 658 women, 147 had previously noted urolithiasis in past, 124 of them were associated with this disease (the group with a positive history of urolithiasis), 511 had not previously sought medical help from a urologist for stones of the urinary system (the group with a negative history of urolithiasis). In total, 95 (14.4%) women with calculi in the urinary tract were identified. In the group with a positive history of urolithiasis, stones were detected in 22.4% of cases, with a negative one – in 12.1%. The most frequent localization of concretions in all groups was the lower group of calyx. The size of the concretions varied in the group with a negative history of urolithiasis from 5.70±0.77 mm to 7.50±0.50 mm, in the group with a positive history of urolithiasis – from 5.00±0.56 mm to 21.75±8.24 mm. Conclusion. The present study showed that the true incidence of urolithiasis is 14,4%, which is several times higher than the official figures. To study the true incidence of urolithiasis, it is necessary to conduct large epidemiological studies in the russian population.
