【摘要】 目的:评价用多次尿棘红细胞计数鉴别肾小球性及非肾小球性血尿的应用价值。方法:用普通光镜通过比较80例(经肾活检证实)各类型肾小球疾病患者和50例非肾小球疾病患者的一次及多次血尿标本棘红细胞百分数,来评价多次尿棘红细胞检查对血尿定位诊断的价值。结果:以棘红细胞数≥5%的标准对诊断肾小球性血尿的特异性为100%,敏感性为90.0%。结论:与一次尿检比较,多次尿棘红细胞检查可提高棘红细胞的检出率,此法对肾小球性血尿定位诊断的准确性更好。更多还原

【Abstract】 Objective:To evaluate the value differentiating glomerular hematuria from non-glomerular hematuria with multiple urine acanthocyte（G₁ cell）counts.Methods:Urine samples of 80 hematuria cases with various glomerular diseases and 50 cases without glomerular diseases were observed with single and multiple urine acanthocyte counts under light microscope.Results:As a diagnostic standard,the specificity and sensitivity of G₁≥5% were 100%and 90.0% in diagnosis of glomerular hematuria.Conclusion:G₁ cell is recognized easily,and it’s more sensitive and accurate with acanthocyte counts of multiple urine than that of single urine for hematuria position diagnosis.更多还原
