UF-100尿液自动分析仪和显微镜检测RBC形态在鉴别肾性血尿中的比较

目的探讨尿液RBC形态检测的临床意义。方法采用UF-100和显微镜法对118例尿液标本进行正形(均一性)和异形(非均一性)RBC的检测,将两者结果进行比较分析。结果62例肾性血尿患者中显微镜检测有56例异形RBC增高,临床诊断符合率为90.3%;UF-100检测有58例为非均一性RBC,临床诊断符合率为93.5%。56例非肾性血尿中显微镜检测有54例正形RBC增高,临床诊断符合率为96.4%;UF-100检测有55例为均一性RBC,临床诊断符合率为98.2%。两法比较,经配对x2检验,P>0.05,结果无显著性差异。而肾性和非肾性血尿组相比,经四格表资料x2检验,P<0.05,结果显示两组有显著性差异。结论UF-100和显微镜对RBC形态的检测都可以用于鉴别诊断肾性和非肾性血尿。尤其是UF-100可为临床诊断疗效观察和判断预后起到非常重要的作用。

Determination of erythrocyte shapes for differential hematuria by UF-100 system and microscope

Objective To explore the clinical significance of determing erythrocyte shapes in urine. Methods Normal(isomorphic) and abnormal(dysmorphic) erythrocytes of 118 urine samples were determined by UF-100 urine automated analyzer system and microscope, then analysed the results between them. Results 56 of 62 samples of the renal hematuria, abnormal erythrocytes increased by microscope observation, with 90.3% corresponding rates. While 58 samples were detected dysmorphic erythrocytes by UF-100 determination, with 93.5% corresponding rates. 54 of 56 samples without the diseases of the renal group, normal erythrocytes were increased under the microscope, with 96.4% corresponding rates, and dysmorphic erythrocytes in 55 samples, with 98.2% corresponding rates. It was not showed significantly different between two results, but showed significant difference between renal group and no disease of renal group. Conclusions Determination of erythrocyte shapes are conducive to diagnose renal or non-renal hematuria. Using UF-100 system is bettter for differential diagnosis, observing the effect and evaluating prognosis in the urinary diseases.
