[Functional state of the kidneys in patients with acute cerebrovascular disorders].

A clinico-laboratorial study of the functional state of the kidneys in 54 patients with severe hemorrhagical and ischemic brain strokes established intensified glomerular filtration in a relatively preserved water excretional, concentrational, Na and K uretical kidney function. The detected azotemia is considered as a result of excessive production of residual blood over the increased function of the kidneys to their elimination. Classical acute kidney insufficiency developed in 3 patients with severe disturbances of hemocirculation.
