[Morphological characteristics of nephrosclerosis of different etiologies].

Morphology of nephrosclerosis at the early stage of its development is characterized by its nosological specificity which is determined by qualitative alterations and by the degree of renal structural components involvement into the sclerotic process. Complex morphometric assessment allows one to reveal and make it objective the morphological differences between nosological variants of nephrosclerosis. All the structural renal components equally undergo sclerosis at the late stages of nephrosclerosis and this leads to the leveling off the nosological specificity in the majority of cases. Arterial hypertension in chronic glomerulonephritis and chronic pyelonephritis favours the progressing of the nephrosclerosis and leveling off its nosological differences.
