摘　　要：目的通过对尿芽孢形红细胞的检查,为肾小球性与非肾小球性血尿的诊断提供依据。方法用位相显微镜检查血尿中芽孢形红细胞的比例,并做统计分析。结果诊断肾小球性血尿,以芽孢形红细胞百分率≥5%为诊断标准,其敏感性为48.9%,特异性为100%;以芽孢形红细胞百分率≥4%为诊断标准,敏感性为63.8%,特异性为100%;以芽孢形红细胞百分率≥3%为诊断标准,敏感性为74.5%,特异性为99%;以芽孢形红细胞百分率≥2%为诊断标准,敏感性为85.1%,特异性为96.1%,以芽孢形红细胞百分率≥1%为诊断标准,敏感性为89.4%,特异性为88.3%。结论以芽孢形红细胞百分率≥2%诊断肾小球性血尿,敏感性和特异性均较好,可以做为鉴别血尿来源的一种有效的方法,值得临床推广。Objective To provide evidences for diagnosis of glomerular hematuria and non-glomerular hermaturia through the examination of urine sporeshaped red blood cell. Methods The percentage of Sporeshaped Red Blood Cell（SRBC） in hematuria was examined and analyzed by the phase-microscope. Results When the percentage of SRBC was more than 5%, the sensitivity and specificity of glomerular hematuria＇s diagnosis were 48.9% and 100%, respectively. When the percentage of SRBC was greater than 4%, the sensitivity and specificity of it were 63.8% and 100%, respectively. When the percentage of SRBC was larger than 3%, the ＂sensitivity and specificity of it were 74.5% and 99%, respectively. When the percentage of SRBC exceeded 2%, the sensitivity and specificity of it were 85.1% and 96.1%, respectively. Nevertheless, while the percentage of SRBC was more than 1%, the sensitivity and specificity of it were 89.4% and 88.3%, respectively. Conclusion When the percentage of SRBC was larger than 2%, its sensitivity and specificity were better to diagnosis of glomerular hematuria. It was an available method for the identification of hematuria source and to be worth to the extention of clinical application.
