    Abstract:
    An experience with 20 patients with renovascular hypertension and renal insufficiency secondary to renal artery stenosis is presented. The mean follow-up was 29 months. Eighteen patients had atherosclerotic renal artery stenosis and two patients had transplant renal artery stenosis. The mean preoperative blood pressure of 162 +/- 5 mmHg decreased significantly to 105 +/- 2 mm Hg (p less than 0.001). The serum creatinine also decreased from a mean preoperative level of 4.7 +/- 0.7 mg/dl to a mean postoperative level of 2.3 +/- 0.3 mg/dl (p less than 0.001). Similarly, the creatinine clearance improved from a mean preoperative level of 28 +/- 2 ml /min to a mean postoperative level of 45 +/- 8 ml/min (p less than 0.03). Four patients (20%) with improved renal function died from 4 days to 15 months postoperatively. Two patients (10%) have progressed to end stage renal disease. These findings demonstrate that renal revascularization is clearly beneficial in the short-term and long-term improvement of renal function.
