title: Prognostic value of renal vein renin determination in suspected renovascular hypertension.
abstract: Surgical correction of unilateral renal artery stenosis was performed in 31 hypertensive patients. Preoperative renal vein renin ratios (RVRR) before and after dihydralazine stimulation were measured in all patients. Postoperative blood pressure were normal in 12, improved in 17 and unchanged in 2 patients. Six patients did not have renin lateralization, but all were cured or improved after surgery. RVRR was a poor predictor of the results of surgery in patients with unilateral renal artery stenosis.
