尿MCV和RDW测定鉴别血尿来源

IDENTIFYING THE SOURCE OF HEMATURIA BY MCV AND REW

采用Ｆ－８００血细胞分析仪，分析尿沉渣中的红细胞，结果发现：肾小球性血尿的平均红细胞体积（ＭＣＶ））为５９．１±６．１６ｆｌ，明显低于非肾小球性血尿的ＭＣＶ（９６．４±６．３５ｆｌ）（Ｐ＜０．０１），两组也与健康人运动后血尿的ＭＣＶ（３３．１±５．７８ｆｌ）有显著差别（Ｐ＜０．０１）。认为通过测定血尿ＭＣＶ和红细胞容积分布宽度（ＲＤＷ），可以将肾小球性血尿、非肾小球性血尿、健康人运动后血尿区分开来，为判断血尿来源提供依据。

As result of analysing erythrocyte in ruinary sediment by F-800 red cell analyer(RCA),It was found that the mean corpuscular volume(MCV)in glomerular hematuria is adout 59.1±6.16 fl,obviously lower than that of non-glomerular hematuria (about 96.4 ±6.34 fl)(P<0.01),and these two groups above also have obvious difference to that of normal persons exertional hematuria(about 33.1 ±5.78fl )(P<0.01),so from all above,we can discriminate glomerular hematuria and non-glomerualr hematuria by MCV and red cell distri-bution width(RDW), and tell the origin of hematuria.
