摘　　要：目的探讨UF-500i尿沉渣分析仪检测在排除患者尿路感染(UTI)中的临床价值。方法该院2013年4月至2014年3月500份尿液标本,同时进行细菌培养、UF-500i尿沉渣分析和尿干化学分析,比较UF-500i尿沉渣分析和尿干化学分析法的检测灵敏度、特异度、与细菌培养结果的符合率。结果 500份尿样中,细菌培养阳性180例。UF-500i法与细菌培养检测符合率为98.33%(177/180),干化学法与细菌培养检测符合率为91.67%(165/180),两种方法符合率比较差异有统计学意义(χ2=4.204,P<0.05)。UF-500i法检测敏感度和特异度分别为98.33%、99.06%,干化学法检测敏感度和特异度分别为为91.67%、95.31%,差异均有统计学意义(P<0.05)。结论 UF-500i法可作为疑似UTI患者的初筛项目,以为临床治疗提供及时的信息。Objective To investigate the value of UF-500i urinary sediment analyzer in diagnosis for urinary tract infection. Methods A total of 500 urine specimens were collected in Guanghe Hospital of Traditional and Western Medicine from April 2013 to March 2014. All the specimens were did bacterial culture,detected by UF-500i urinary sediment analyzer and urine dry chemistry analysis. The sensitivity, specificity and coincidence with the bacterial culture result of the UF-500i urinary sediment analyzer and u- rine dry chemistry analysis result were compared. Results There were 180 specimens with positive bacterial culture results. The coincidence rates of UF-500i urinary sediment analyzer and the bacterial culture results was 98. 33% （177/180）, the coincidence rates of urine dry chemistry analysis and the bacterial eulture results was 91.67 % （165/180）, there was a significant difference be- tween them（χ2 = 4. 204, P〈0.05）. The sensitivity and specificity of UF-500i urinary sediment analyzer（ 98.33 %, 99.06 % ） and u- rine dry chemistry analysis （91.67% ,95.31%） were significant different（P〈0.05）. Conclusion UF-500i urinary sediment analyzer could be used as an early screening method in diagnosis for urinary tract infection.
