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.
约10%的高血压病例是由肾脏因素引起的。肾血管造影为肾动脉和肾实质病变的形态学诊断提供了最清晰的证据。在180例有肾血管造影病理结果的高血压患者中，最常被证实为肾盂肾炎改变。其次是动脉病变、肾积水、多囊性退变和发育不全。然而，在108例血压值正常的患者中也发现了这些疾病。可能涉及到一些疾病不存在血液动力学影响的病例。在晚期病例中，发现器官有缩小。部分病例中，肾脏大小在正常范围内。只有一些高血压患者有器官增大。当存在多条肾动脉时，高血压的发生率明显高于每侧肾脏由一条动脉供血的情况。
