摘要
目的评价用三次尿棘红细胞(G1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经肾活检证实的75例各类型肾小球疾病患者和60例非肾小球疾病患者一次及三次血尿标本G1细胞数,并作统计分析。结果以G1细胞≥5%为标准一次尿检敏感性为74.7%,三次尿检对诊断肾小球性血尿的特异性为100%,敏感性为93.3%。结论与一次尿检比较,三次尿G1细胞检查可提高G1细胞的检出率,对肾小球性血尿定位诊断的准确性更好。
Objective To evaluate the value differentiating glomerular hematuria from non-glomerular hematuria with multiple urine acanthocyte(G1 cell)counts.Methods Urine samples of 75 hematuria cases with various glomerular diseases and 60 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 93.3% in diagnosis of glomerular hematuria.Conclusion G1 cell is easily recognized,and it’s more sensitive and accurate with acanthocyte counts of multiple urine than that of single urine for hematuria position diagnosis.
