尿沉渣分析仪和尿干化学分析仪联合检测对尿路感染的诊断价值

摘要

目的评价尿干化学分析仪PRO-II和尿沉渣分析仪UF-500i联合检测对尿路感染的诊断价值。方法回顾性分析疑为尿路感染的1600份住院患者尿液标本，对比分析同期作为诊断金标准的尿液细菌定量培养结果与白细胞酯酶、亚硝酸盐、尿沉渣白细胞计数和尿沉渣细菌计数结果，对照评价。结果干化学亚硝酸盐、白细胞酯酶、尿沉渣细菌计数与尿定量培养结果对尿路感染诊断具有统计学意义，尿沉渣白细胞计数无统计学意义；尿干化学分析和尿沉渣分析联合检测诊断尿路感染的灵敏度为96.2%、特异度为92.3%、阳性预测值为78.5%、阴性预测值为86.8%、总符合率为93.4%。结论联合应用PRO-II尿干化学分析仪和UF-500i尿沉渣分析仪与尿定量培养结果对尿路感染诊断具有高度一致性，对尿路感染的早期筛查与诊断具有重要的临床价值。%Objective To evaluate the ef iciency of routine urine test and UF-500i urine analysis in diagnosis of urinary tract infections.Methods To analysis retrospective 1660 urine of urinary tract infections ,contrarstive analysis urine bacteria culture、leukocyte esterase,nitrite、numeration of leukocyte and bacteria counting in the same priod. Results Urine bacteria culture、leukocyte esterase、nitrite and bacteria counting have statistical significance for urinary tract infections,but numeration of leukocyte no statistical significance for urinary tract infections. Sensitivity of rouitine urine test and UF-500i urine analysis is 96.2%,specificity is 92.3%,positive predictive value is 78.5%,negative predictive value is 86.8%,total coincidence rate is 93.4%. Conclusion Combined application of rouitine urine test and UF-500i urine analysis and urine bacteria culture are uniform in diagnosis of urinary tract infections and have the diagnostic value of the early urinary tract infections screening.
