The Relation Between the Urinary Excretion of Citric Acid and Calcium; Its Implications for Urinary Calcium Stone Formation

Abstract
Parallel changes in Ca and citrate content of the urine were observed in patients in whom variations in urinary Ca excretion were induced by variations in diet and hypoparathyroidism. The level of citrate excretion was influenced by the Ca excretion. This study is of importance in the consideration of proper treatment of patients with Ca stones of the urinary tract.
