[Pathophysiology of renal hypertension (author's transl)].

The review discusses the pathophysiology of the renal mechanisms of blood-pressure control. The physiology of the renin-angiotensin system is described and the mineralo-corticoid function has also been considered. The implications of alterations of these systems in various nephropathies are briefly summarized (renal artery stenosis, infarction, Page's syndrome, acute glomerulonephritis, essential hypertension a.o.).
