Abstract
Thirty-two patients with hypertension were given a pressor dose of angiotensin in the course of individual kidney function tests. In eight patients with unilateral renal artery stenosis the differences in urine sodium and creatinine concentration between the affected and the nonaffected kidney did not become greater with angiotensin infusion. In four patients with unilateral pyelonephritis and falsely positive individual kidney function tests, these tests became normal following angiotensin infusion. It is concluded that angiotensin infusion is not a useful means of improving the results of individual kidney function tests.
