Value of Combined Intravenous Renal Arteriography and Pyelography in the Diagnosis of Renovascular Hypertension

Abstract

1. The technique of combined intravenous renal arteriography and pyelography is described and results in 848 hypertensive patients are reported. 2. The procedure was tolerated better than Seldinger arteriography and the diagnostic accuracy for renal artery stenosis was 95%. 3. The prevalence of renovascular disease was 7%. 4. Cost-effectiveness calculations favour combined intravenous arteriography and pyelography rather than the usual approach based on assessment of the indications for Seldinger arteriography from clinical and urographic signs.
