[The epidemiology of the most prevalent kidney diseases in the nationalities of the North].

Health examination of events in the Evenki Autonomic Region and events in Yakutia using multiprofile questionnaires revealed high incidence of renal diseases: chronic pyelonephritis, chronic cystitis, nephroptosis. The former occurs most frequently, runs in association with nephroptosis and chronic cystitis, affects females more frequently than males. Nephroptosis is attributed to a nomad's life which the natives lead. In spite of high urinary oxalates and urates levels, urolithiasis in the Northerners occurs relatively seldom.
