Diagnosis of Renal Arterial Lesions

The diagnosis of renal arterial disease is made by arteriography, but, at the present time, this technique is not used in every hypertensive patient. Since renal arterial stenosis often causes a remedial type of hypertension, arteriography should be performed whenever occlusive disease is suspected. Accordingly, we reviewed our six years' experience with diagnosis of these lesions to determine the features of the usual examination of the hypertensive patient which suggest the presence of renal stenosis and can serve as indications for renal arteriography. This report describes the importance of some clinical and urographic features in the diagnosis of this type of renal hypertension. Clinical Material There were 139 patients; 82 had unilateral main renal arterial disease, and 35 had bilateral lesions; 20 had stenosis of one or more primary arterial branches to one kidney, and 2 had bilateral branch arterial disease.* To determine whether these patients differed greatly from essential
