The diagnosis of hypertension secondary to renal artery or kidney disease presently depends upon abnormalities detected by renal angiography, radioactive isotope renal scanning, and differential ureteral catheterization. The comparative accuracy of each of these techniques, however, and the role each should have in the examination of patients with high blood pressure, have not been clarified.1-3 The purpose of this paper is to describe the application of these methods and their correlation in the evaluation of 130 hypertensive patients. On the basis of the data obtained, a diagnostic program has evolved for the evaluation of patients suspected of having hypertension of renal artery or kidney origin. Material and Methods A total of 130 patients with arterial hypertension were examined by percutaneous transfemoral retrograde catheter aortography on the basis of the following criteria: (1) sudden onset of hypertension, (2) hypertension refractory to medical management, (3) hypertension occurring below age of 40
