[The correlation of different forms of primary glomerulonephritis today and their diagnostic criteria (the work experience of a nephrology department and a clinico-morphological analysis of 3000 cases)].

The author reviews the structure of nephropathies on the basis of an analysis of the clinicomorphological data obtained during the follow-up of 3000 patients examined at the nephrological center. In a group of primary glomerulonephritis, the mesangioproliferative form occurred most frequently (68%), the membranoproliferative form was encountered in 27.2% of cases, and the membranous form in 1.8%. Over the recent years not a single case of acute glomerulonephritis has been observed. Analysis of the diagnostic criteria allowed the antibody variety only to be regarded as an independent pattern of rapid-progressing glomerulonephritis. Equally to the manifestations of glomerulonephritis proper, mesangial proliferation should be also viewed as a possible nonspecific response to the other pathological processes. Focal glomerulosclerosis as a disease entity is to be excluded from the nomenclature of glomerulonephritis.
