THIS SUBJECT has created intense interest and diverse opinions recently among those who treat patients having hypertension and renal disorders. Part of the interest may be attributed to rapid advances in diagnostic and surgical procedures. This is especially true of renal-vascular lesions responsible for the renal stimulus of hypertension. When the proper method of investigation is carried out, a higher incidence of renal arterial lesions is found than formerly thought. These lesions include atherosclerotic plaques, thrombosis, aneurysm, fibrosis, and arteriovenous fistula. The parenchymal lesions of unilateral pyelonephritis, infarct, cyst, tumor, and hydronephrosis continue to account for 2% of the causes of remedial hypertension. Many investigators place great emphasis upon 1 or 2 diagnostic tests for the evaluation of "renal" hypertension. Their application may be advocated out of proportion to actual value. Thus many equally valuable diagnostic procedures may receive inadequate attention. With our incomplete knowledge of the etiology of
