目的 为了提高血尿鉴别诊断的准确性和特异性 ,寻找一种有具体意义的特异性形态的红细胞作为判断标准。方法 对 2 41例各类型肾小球疾病患者和 88例非肾小球性疾病患者的血尿标本 ,用位相差显微镜观察并确定具有明显的芽胞状的红细胞 (G1)。结果 用G1≥ 5 %的标准对诊断肾小球性血尿的特异性为 10 0 % ,敏感性为 82 2 % ;若在酸性浓缩尿中 ,其敏感性为 90 6 % ,特异性为 10 0 %。在非肾小球性血尿中G1<5 %。结论 该细胞形态特殊易于辩认。通过计数酸性浓缩尿中G1百分率 ,能正确诊断肾小球性血尿和非肾小球性血尿。
Objective To improve the accuracy and specificity of differential diagnosis of hematuria, to find a specific significance of the specific morphology of red blood cells as a criterion. Methods Serum and urine samples from 241 patients with various types of glomerular diseases and 88 patients with non-glomerular diseases were observed by phase contrast microscopy and identified as spicular erythrocytes (G1). Results The specificity of G1 ≥ 5% was 100% for diagnosis of glomerular hematuria and 82 2% for sensitivity. In the case of acidic concentrated urine, the sensitivity and specificity were 90.6% and 100% respectively %. G1 <5% in non-glomerular hematuria. Conclusion The cell morphology is easy to identify. By counting the percentage of G1 in acidic concentrated urine, glomerular hematuria and non-glomerular hematuria can be correctly diagnosed.
