On the Use of Renal Angiography and Intravenous Urography in the Investigation of Renovascular Hypertension

. The value of renal angiography for revealing renovascular changes has been investigated in 126 patients with hypertension, and in 102 of them a comparison was made with i.v. urography. It was concluded that i.v. urography does not reveal renovascular changes and thus the primary investigation should be renal angiography, in some cases followed by urography in the same session.
