Random urine samples of 352 children in the age group of 5-12 yrs were studied for urinary calcium-creatinine ratio (Uca/Ucr mg/mg). None had any predisposing factor for secondary hypercalciuria. Calcium and creatinine both were estimated by colorimetric method. We observed that Uca/Ucr in the general pediatric population was skewed, the pattern was similar to that described in western children and it was independent of age and sex. The mean and standard deviation (SD) of Uca/Ucr was 0.10 +/- 0.094. Considering mean +2SD as the upper limit of normal, which was 0.29 in this series, the prevalence of hypercalciuria was 6.5%.
