title: Renal angiography may be used primarily in the diagnosis of renovascular hypertension.
abstract: Three hundred and twenty consecutive patients with hypertension were referred to examination with intravenous urography. Only 2 of the 320 urograms performed showed abnormalities possibly related to hypertension. Renal angiography was performed in 39 (12%) of the patients. Seventeen (7%) subjects had renal artery stenosis, of whom 8 (2.5%) were referred to surgery. Four became normotensive and the other 4 had a more treatable hypertension. Urography is an expensive and insensitive method for evaluation of patients with hypertension and should be abandoned. Proper treatment of renovascular hypertension demands the performance of renal angiography. We therefore suggest a program for primary use of renal angiography in the examination of patients with suspected renovascular hypertension.
