血尿为儿童期常见的尿异常。据有关无症状患儿的筛选研究,镜下血尿的发生率约为0.05-2%,而采用现代诊断方法则大约40%的单纯血尿症可归属于“特发性血尿”。1981年Moore等报道23例高尿钙症有8例开始仅表现为血尿而无尿结石。以后,作者及其他学者发现肉眼血尿可能是床结石的前躯表现。但以前血尿在儿童中未能对尿钙排泄作常规检查,故对血尿患儿的高尿钙的发生率还不清楚。为此,作者进行了有关研究。
Hematuria is a common childhood urine abnormalities. According to screening studies on asymptomatic children, the incidence of microscopic hematuria is about 0.05-2%, whereas about 40% of simple hematuria with modern diagnostic methods can be attributed to “idiopathic hematuria.” In 1981, Moore et al. Reported that in 23 cases of hypercalciuria, only 8 cases started to show hematuria without urinary stones. Later, the author and other scholars found that gross hematuria may be the forerunner of bed stones. However, before hematuria failed to routine examination of urinary calcium excretion in children, so the incidence of high urinary calcium in children with hematuria is not yet clear. To this end, the author conducted a study.
