摘要
目的评价血液分析仪检测尿红细胞平均体积对鉴别血尿来源的临床诊断价值。方法按照纳入排除标准收集关于血液分析仪检测尿红细胞平均体积用来鉴别血尿来源的文献22篇,采用Meta分析方法进行统计分析。结果肾小球性血尿患者尿红细胞平均体积值小于非肾小球性血尿患者,两者差异有统计学意义;但不同文献报道尿红细胞平均体积的结果间存在显著异质性(P<0.001)。结论所评价的文献提供的诊断性试验评价指标欠缺,用尿红细胞平均体积诊断血尿来源的标准尚不统一,不能肯定其临床诊断价值。
Objective To evaluate the clinical diagnosis value of detecting mean eorpulseular volume（MCV） for identifying the source of hematuria by hematoanalyser. Methods 22 primary documents on detecting urine MCV for identifying the source of hematuria by hematoanalyser were collected on the basis of inclusive and exclusive standard and were analyzed by meta-analysis. Results The urine MCV in glomerular hematuria patents is lower than that in non- glomerular hematuria patents, which showed a difference of statistical significance. However, different documents reported that there was notable heterogeneity among the detected value of urine MCV（P 〈 0.001）. Conclusion Because of lacking in the assessment indexes of diagnostic test from the documents, no unified standard was presented in the diagnosis of hematuria by detecting urine MCV and its clinical diagnostic value could not be confirmed.
