title: [Changes in plasma renin and aldosterone after parathyroidectomy in patients with hyperparathyroidism].
abstract: The plasma renin activity and its changes after parathyroidectomy indicate a preserved internal secretory renal function in dialyzed patients. The PRA values before parathyroidectomy are not unequivocally related to the blood pressure reading. After parathyroidectomy during the initial months the renin and aldosterone plasma levels decline in patients with secondary and primary HPT (p < 0.001), the urinary Na/K quotient rises in primary HPT (p < 0.05) and the systemic blood pressure declines in dialyzed patients with secondary HPT (p < 0.001). The findings suggest relations between the two hormonal systems during hyperparathyroidism and in the early stage after parathyroidectomy. Parathormone probably stimulates renin secretion. After a prolonged time interval following operation the parathormone levels in the blood steam reach normal levels and the same probably applies to intracellular calcium in cells of the iuxtaglomerular apparatus along with PRA.
