Kidney transplant artery stenosis. Interrelationship between blood pressure, kidney function, renin-aldosterone system and body sodium content.
Among 9 hypertensive recipients with kidney transplant artery stenosis (KTAS) evidence of increased activity of the renin system was present in 3. Surgical repair of KTAS in 4 recipients resulted in an increase in renal plasma flow and glomerular filtration rate associated with a decrease in exchangeable sodium and blood pressure. Peripheral plasma renin and aldosterone values were normal before and after operation in all. It is suggested that sodium retention may counterbalance increased activity of the renin system in KTAS. Preoperative determinations of plasma renin do not predict the effect of surgical repair of KTAS on hypertension.
