| Abstract: | Eleven patients with renovascular arterial hypertension were studied, 9 of whom had unilateral renal artery stenosis and 2 bilateral renal artery stenosis. Angiotensin increased sodium excretion in the contralateral kidney and did not change it in the stenotic one. In bilateral stenosis angiotensin increased sodium excretion significantly in both kidneys. The difference in response to angiotensin between patients with unilateral stenotic kidney and those with bilateral stenosis is apparently unrelated to arterial blood pressure distal to the arterial stenosis. |
