INTRODUCTION. Study of epidemiology of hydrocephalus cases is currently problematic issue due to its abundance, high levels of associated mortality and negative socio-economic consequences. AIM. Perform a dynamic analysis of epidemiological characteristics of progressing hydrocephalus cases in kids in Republic of Tatarstan from 1995 to 2022. MATERIALS AND METHODS. We analyzed medical histories of 1288 kids with different forms of progressing hydrocephalus cases, that currently live in Republic of Tatarstan. RESULTS. From 1995 to 2022 we observed a statistically significant growth of hydrocephalus cases from 2,76 to 5,05 per 100 000 kids. From 2013 to 2022 we observed a tendency that hydrocephalus cases became more abundant from 61,93 to 67,31 cases per 100 000 kids. We observed significant increase in appearance of pathology in boys (60.9 %), than in girls (39.1 %). The most common cause of hydrocephalus cases during the time of the study were intracranial non-traumatic hemorrhage (36.1 %) and tumors of central nervous system (29.2 %). CONCLUSION. Rates and spread of hydrocephalus cases in kids in Republic of Tatarstan from 1995 to 2022 gradually increases. It is most common in boys and in kids that are aged from 28 days to 3 month.
