尿红细胞形态及平均体积在在血尿定位应用分析

目的探讨尿红细胞形态及尿红细胞平均体积(MCV)检查在判定血尿来源定位应用价值。方法选取100例血尿的标本作为考察对象,Sysmex XN-1000全自动血球分析仪检测尿红细胞平均体积(MCV),并用相差显微镜检查尿红细胞形态学,观察和分析肾小球性血尿组(glomerular hematuria,GH)和非肾小球血尿组(non glomerular hematuria,NGH)尿红细胞形态及尿红细胞平均体积的差异。结果肾小球性血尿(GH)组尿MCV值(63.71±6.03)fl明显低于非肾小球性血尿(NGH)组MCV值(92.37±12.11)fl(P0.05)且尿MCV不高于72.0fl,变形红细胞80%呈多形型。结论尿中红细胞形态及红细胞平均体积特征分析可作为血尿定位诊断和鉴别诊断的方法之一,有助于判断血尿的来源提供临床参考依据。

The application value of urine red blood cell morphology and mean corpuscular volume in localization of hematuria

Objective To investigate the application value of urinary red cell morphology and mean corpuscular volume (MCV) in localization of hematuria. Methods Select 100 cases of hematuria samples as investigation object,Sysmex XN-1000 automatic blood cell analyzer was used to detect urine mean corpuscular volume (MCV),and phase-contrast microscope was used to observe urine red blood cell morphology. Observation and analysis of the difference of urinary red cell morphology and mean corpuscular volume between glomerular hematuria group (GH) and non glomerular hematuria (NGH) group. Results The MCV values (63.71+6.03) fl in glomerular hematuria (GH) group were significantly lower than MCV values (92.37+12.11) fl in glomerular hematuria (NGH)group. the urine MCV values are not higher than 72.0 fl,The rate of deformed of red blood cells >80% and the red blood cells are polymorphic type. Conclusion The characteristics analysis of urine red blood cell morphology and mean corpuscular vol-ume can be used as one of the methods in the localization diagnosis and differential diagnosis of hematuria ,It is helpful to deter-mine the origin of hematuria and provide clinical reference.
