Abstract
Patients (15) were operated upon for renovascular hypertension associated with bilateral renal artery stenosis. Followup has been for 1 to 12 yr. Four of 5 patients with positive split renal function studies and 3 of 5 patients with positive renal vein renin assays underwent unilateral operations on the positive side. All of these patients were cured or improved. The guide for unilateral operations in hypertensive patients with bilateral renal artery stenosis by angiography was the physiological information obtained from the preoperative screening tests, especially the plasma renin activity ratios of the 3 different veins and the split renal function studies.
