高钙尿症,特别是特发性高钙尿症是儿童尿路疾患的一种病因。Rofer和Maly报告正常儿童尿钙排钙<4 mg/kg体重/24小时。作者从随机尿标本中测定尿钙/肌酐(Ca/Cr)含量比率(mg/kg),发现3个月～18岁儿童正常Ca/Cr比率为0.06±0.06。此值与Stapelton对6～13岁儿童研究结果相似。比率大于0.18将初步诊断为高钙尿症,如尿钙排泄量>4毫克/公斤体重/24小时则可确诊。儿童高钙尿症常见病因是:制动、速尿或利尿酸
Hypercalciuria, especially idiopathic hypercalciuria, is a cause of urinary tract disorders in children. Rofer and Maly report normal urinary calcium excretion in children <4 mg / kg body weight / 24 hours. The authors measured urinary calcium / creatinine (Ca / Cr) content ratio (mg / kg) from random urine samples and found a normal Ca / Cr ratio of 0.06 ± 0.06 for children from 3 months to 18 years of age. This value is similar to Stapelton’s findings for children 6-13 years of age. Rates greater than 0.18 will be initially diagnosed as hypercalciuria, such as urinary calcium excretion> 4 mg / kg body weight / 24 hours can be diagnosed. Common causes of hypercalciuria in children are: brake, furosemide, or diuretic
