Hypocitraturia in patients with urolithiasis

Abstract

The urinary citrate/creatinine ratio was evaluated in 25 children with idiopathic calcium urolithiasis and 24 controls. The mean (SD) urinary citrate/creatinine ratio in controls and patients was 0.510 (0.205) and 0.181 (0.076), respectively, a statistically significant difference. In neither group was there a relation between age and urinary citrate excretion.
