　　目的探讨FUS-200全自动尿沉渣分析仪在尿路感染诊断中的应用价值。方法对219例怀疑尿路感染患者留取的尿常规标本进行尿有形成分分析、清洁中段尿进行细菌培养，以尿细菌培养结果为尿路感染确诊的金标准，计算FUS-200尿沉渣分析仪测定的白细胞数、细菌计数对尿路感染诊断的敏感性、特异性、阳性预测值、阴性预测值。结果白细胞的敏感性虽高，为88.0%，但它的特异性最低，仅为55.9%；细菌计数的特异性最高，为91.2%，但敏感性稍低，为77.1%；而白细胞和细菌计数联合诊断尿路感染的敏感性、特异性、阳性预测值、阴性预测值都很高，分别为89.7%、88.4%、84.7%、91.5%。结论 FUS-200全自动尿沉渣分析仪可作为临床诊断尿路感染的初筛方法，它具有快速、经济、准确、重复性好等优点，但尿路感染的确诊需要依据细菌培养的鉴定和药敏结果。

Objective To study the application value of FUS-200 full-automatic urine sediment analyzer in diagnosing urinary tract infection(UTI). Method We determined the urine speciments and cultured the clear-catch midstream urine speciments from 219 patients suspected UTI. Using the results of urine bacteria culture as golden standard in diagnosing UTI, We coculated the sensibility, specificity, positive predictive value and negative predictive value of WBC counts and bacteria counts(BACT) detected by FUS-200 in diagnosing UTI. Results The sensitivity of WBC was high(88.0%),but the specificity was minimum (only 55.9%).The specificity of BACT was the highest (91.2%),but the sensitivity was slightly lower (77.1%).When WBC was combined with BACT, the sensitivity, specificity, positive predictive value and negative predictive value were very high (89.7%,88.4%,84.7%,91.5%).Conclusion FUS-200 urine sediment analyzer can be used as screening methods for clinical diagnosis of UTI ,and it is fast, economical, accurate and repeatable.But UTI diagnosis need to based on the urine bacteria identification and drug sensitivity results.
