摘要
采用血细胞计数仪测定42例血尿患儿尿红细胞平均体积(R-MCV)对血尿来源进行判断,并与光镜下尿红细胞形态学检查进行比较。其中肾小球性血尿26例,非肾小球性血尿16例。结果表明41例与临床诊断血尿部位相符。肾小球性血尿R-MCV明显小于非肾小球性血尿(P<0.01),且小于自身血R-MCV(P<0.01)。如果以70fl为界区分肾小球性与非肾小球性血尿,其诊断准确率为97.6％,明显高于光镜下尿红细胞形态学检查的正确率(83％,P<0.01)。是一种简便、快捷、客观的血尿筛选方法。还对肾小球性血尿红细胞显著缩小的机理进行了探讨。
Urinary red cell MCV was measured in 42 cases with hematuria by using blood cell counting meter, as a judgement for the source of hematuria,and to compare it with urinary red cell morphology un-der microscope. Among them 26 cases with glomerular hematuria (GH) and 16 cases with non-glomerular hematuria (NGH) were diagnosed clinically. The results showed some C ncidence with the type of hematuria by clinical diagnosis in 41 cases. The R-MCV'in GH was significantly smaller than that in NGH(F<0. 01) and smaller than blood MCV. When<70 fl of MCV was defined as value for differentiation of GH from NGH.its diagnostic accuracy was 97. 6%, which was apparently higher than that obtained by using red cell morphology by microscopy (83% ,P<0. 01). The present study suggested that this method was simple.rapid and objective for screening the source of hematuria. The mechanism of marked shrinkage of RBC in GH was also discussed.
