目的 研究UF-1000i尿有形成分分析仪对诊断尿路感染的价值.方法 采用UF-1000i尿有形成分分析仪检测150份临床尿液标本的白细胞、酵母样真菌及细菌计数,将这3项检测结果结合起来判断是否具有尿路感染(UTI)信息,并记录下具有UTI信息标本的散点图.同时将尿标本进行细菌培养和鉴定,将UF-1000i尿有形成分分析仪的检测结果与之做比较分析.以临床诊断尿路感染的标准作为诊断UTI的金标准,计算UF-1000i尿有形成分分析仪对诊断UTI的敏感度、特异度等评估参数,以及细菌散点图分布与尿细菌培养结果、临床诊断的符合情况.结果 通过对146份标本的比较分析,UF-1000i尿有形成分分析仪阳性检出率为32.9%(48/146),细菌培养阳性检出率为28.8%(42/146),2种检测方法之间差异无统计学意义(χ2=1.79,P0.05),且一致性较好(Kappa=0.775 6).UF-1000i尿有形成分分析仪判断筛选UTI信息的敏感度为76.0%(38/50),特异度为89.6%(86/96),阳性预测值为79.2%(38/48),阴性预测值为87.8%(86/98);UF-1000i尿有形成分分析仪测得细菌的球杆菌分布与细菌培养结果基本一致.结论 UF-1000i尿有形成分分析仪的"YTU信息"研究参数对诊断尿路感染具有重要价值.

Objective To evaluate the application value of UF-1000i automated urine formed elements analyzer in the diagnosis of urinary tract infection. Methods 150 urine specimens were analyzed using the UF-1000i in parallel with detection of leukocyte, yeast-like fungus, and bacteria. These detection results were collected for evaluation of urinary tract infection and scatter grams were recorded. At the same time, these samples were cultured for bacterial identification, which results were compared with that of the UF-1000i. The clinical diagnose criteria of the UTI was performed as golden standard. As compare with results obtained with UF-1000i, the sensitivity and specificity of UF-1000i for diagnosis of urinary tract infection were evaluated, and the consistency were analyzed among scatter grams, bacterial culture and final diagnosis. Results The statistical results from 146 specimens showed that the positive rate of UF-1000i was 32. 9% (48/146), the positive rate of urine culture is 28. 8% (42/146). There was no significant statistical difference found (χ2 = 1.79 ,P = 0. 18 )and Kappa test showed a considerable consistency (K = 0. 775 6). The UF-1000i detection results showed the sensitivity 76. 0% ( 38/50 ), specificity 89. 6% ( 86/96 ), positive predictive value 79. 2% ( 38/48 ) and negative predictive value 87. 8% ( 86/98 ), respectively. The distribution of coccus and bacilli obtained from the UF-1000i testing was basically in accordance with the results of bacterial culture. Conclusion The "UTI-information" of UF-1000i is very important for the diagnosis of urinary tract infections.
