[Significance of renovasography in the elucidation of hypertension].
About 10% of all cases of hypertension are nephrogeneously conditioned. The renovasography gives the clearest evidence for the morphological diagnostics of changes of the renal arteries and the parenchyma. In 180 hypertensive patients with pathological findings of the renal angiography most frequently pyelonephritic changes were proved. Then follow changes of the arteries, kidneys with urinary stasis, polycystic degenerations and hypoplasias. These diseases were, however, also found in 108 patients with normal values of blood pressure. Possibly cases are concerned in which no haemodynamic effect of the disease is present. In advanced findings reductions of organs were registered. In a part of the cases the sizes of the kidneys were found within the normal values. Only some patients with hypertension had enlargements of the organs. When multiple renal arteries were present a hypertension was significantly more frequent than in a supply of the kidneys by means of one artery each.
