The calcium content in a comparison group of children after 120 minutes returned to the baseline, in patients with a renal form of primary hyperparathyroidism its level was greater than 1.3 times. The test was sensitive and provided an opportunity to reveal hypercalcemia in 39 children who had been the normo- and hypocalcemia. The impaired renal function had no effect on the significance of the test. Osmotic hypertension develops under the influence of hypertonic sodium chloride. In osmotic diuresis, the excretions of calcium and sodium cations are interdependent.&nbsp; Increasing sodium in the loops of Henle and distal renal tubules stimulates sodium excretion, decreased reabsorption, which leads to increased levels of calcium in the daily urine in children with primary hyperparathyroidism. Test with sodium chloride made it possible to detect hypercalciuria in 12 (21.43%) children who have had normal levels of calcium in urine.</p> Abdusattor Akhatovich Nasirov Bayakhmedov Fathulla Faizievich Copyright (c) 2022 Author 2022-12-04 2022-12-04 3 4 1 3
