At the beginning of XVII century R. At the beginning of XVII century R. Brite offered the first classification of Brite offered the first classification of nephropathy nephropathy
At the beginning of XX century At the beginning of XX century clinicist Folgart and pathologist Far clinicist Folgart and pathologist Far divided Brite’s illness on three divided Brite’s illness on three groups:groups: - nephrites;- nephrites; - nephroses;- nephroses; - nephroscleroses.- nephroscleroses.
