Abstract

Urinary citrate is a potent inhibitor of calcium-oxalate and calciumphosphate crystal formation. It also forms soluble complexes with calcium, thereby decreasing the calcium-specific ion activity and relative supersaturation of both calcium oxalate and calcium phosphate (1). The present investigation was performed, therefore, to study circadian variations in citrate excretion in patients suffering from calcium urolithiasis and in control subjects.
