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%.
对352名年龄在5至12岁的儿童的随机尿液样本进行了尿钙肌酐比值（Uca/Ucr mg/mg）研究。无一例有继发性高钙尿症的诱发因素。钙和肌酐均采用比色法测定。我们观察到，普通儿科人群中的Uca/Ucr呈偏态分布，其模式与西方儿童中描述的相似，且与年龄和性别无关。Uca/Ucr的平均值和标准差（SD）为0.10±0.094。将平均值+2SD作为正常上限，本系列中该值为0.29，高钙尿症的患病率为6.5%。
