The detection of unilateral renal artery stenosis, a potentially curable lesion, is of utmost importance. The use of excretory urography, radiorenography, split renal function tests, and aortography is frequently unsatisfactory. Modification of the above procedures and new techniques are constantly being sought. The reduction of oxygen saturation and tension of the renal vein blood may be of value in identifying the ischemic kidney with an obstructive lesion.
Renal vein blood was collected anaerobically by renal vein catheterization or direct puncture. Oxygen saturation was analyzed by the Van Slyke method and tension by the Astrup Po2 meter or calculated from the
