全自动尿液有形成分分析仪细菌检测对尿路感染诊断价值的探讨

目的探讨UF-1000i全自动尿液有形成分分析仪细菌信息对临床尿路感染(UTI)诊断的应用价值。方法收集216例临床疑似尿路感染患者尿液样本,分别采用UF-1000i全自动尿液有形成分分析仪和尿液细菌培养及鉴定,比较两者结果。结果 216例临床诊断为尿路感染患者的UF-1000i全自动尿液有形成分分析仪细菌数量检测阳性率为38.0%(82/216),细菌培养阳性率为31.0%(67/216),两种方法检测结果经统计无显著性差异(P0.05)。UF-1000i全自动尿液有形成分分析仪细菌检测诊断尿路感染的敏感度为69.0%、特异性为82.9%、假阳性率为17.1%、假阴性率为31.0%、阳性预测值为73.2%、阴性预测值为79.8%、诊断符合率为77.3%。结论 UF-1000i全自动尿液有形成分分析仪检测简易、快速,细菌检测有助于及时辅助尿路感染临床诊断,可作为临床筛查的手段。

To explore the appilication value of bacteria detection in the diagnosis of urinary tract infection by using the fully auto-mated urine particle analyzer UF-1000i

Objective To study the application value of bacteria detection in the diagnosis of urinary tract infection (UTI) by using the fully automated urine particle analyzer UF-1000i. Methods A total of 216 urine samples from the patients with clinical suspected urinary tract infection were analyzed by the fully automated urine particle analyzer UF-1000i and proceeded with the bacteria culture and identification at the same time. According to the guidelines for the diagnosis of urinary tract infection ,the sen-sitivity,false positive rate,false negative rate,positive predictive value,negative predictive value and accuracy of the diagnosis of urinary tract infections were calculated respectively. And the results derived from fully automated urine particle analyzer UF-1000i and the urine bacteria culture were compared. Results The positive rate of bacteria detection with the fully automated urine parti-cle analyzer UF-1000i and bacteria culture was 37.9% (82/216),31.0% (67/216) respectively(P<0.01). The sensitivity,specificity, false positive rate,false negative rate,positive predictive value,negative predictive value and accuracy for screening urinary tract infection with the fully automated urine particle analyzer UF-1000i were 69.0%,77.3%,82.9%,17.1%,31.0%,73.2%and 79.8%, respectively. Conclusions The detection of bacteria with the fully automated urine particle analyzer UF-1000i is helpful for screening early urinary tract infection.
