[Phospho-calcium metabolism after operation for hyperthyroidism]

Study of data concerning calcium and phosphorus after removal of an adenoma in 60 cases of primary hyperparathyroidism, showed that serum calcium levels always fall. Serum phosphorus usually rises, but not always. There is a fall in urinary calcium in cases which previously had increased calcium in the urine. Phosphorus in the urine falls, but in a variable manner. The authors discuss the role of bony lesions and renal failure.
