title: Surgical therapy for persistent hypertension after renal transplantation.
abstract: The presence of the original diseased native kidneys in renal allograft recipients is associated with an increased prevalence of persisting post-transplant hypertension. In 9 of 10 such transplant patients bilateral nephrectomy of these native kidneys, performed at least 1 year after successful transplantation of a renal allograft, resulted in improved blood pressure control. Although these 10 patients had higher peripheral plasma renin activity (PRA) than normotensive patients (5.9 +/- 1.3 ng/ml/hr versus 1.5 +/- 0.3 mg/ml/hr), selective renal vein renin measurements did not consistently demonstrate higher renin concentrations from the native kidneys. Removal of the original kidneys was beneficial even in some patients who had stenosis of the allograft artery demonstrated by arteriography.
