UF-500i型尿流式分析仪在筛查妊娠期无症状泌尿道感染中的应用

Clinical application of the UF-500i Flow Cytometer in screening the asymptomatic urinary infection of pregnant women

目的:采用UF-500i型尿流式分析仪检测妊娠妇女中段尿,以中段尿细菌培养为"金标准",评价UF-500i型尿流式分析仪在筛查妊娠妇女无症状泌尿道感染(UTI)中的价值。方法:对500份妊娠妇女中段尿标本做细菌培养菌落计数,并与UF-500i型尿流式分析仪结果进行比较。结果:UF-500i型尿流式分析仪阳性检出率为10.4%,细菌培养阳性检出率为8.6%,差异无统计学意义(P>0.05),且一致性较好(Kappa=0.999,P<0.05)。UF-500i型尿流式分析仪筛选UTI的敏感度和特异性分别为88.4%和96.9%,阳性预测值和阴性预测值分别为73.1%和98.9%。结论:UF-500i型尿流式分析仪筛查妊娠无症状UTI具有快速、方便、经济的特点,有很高的实用价值,但要注意尿液污染问题。

Objective： To evaluate the clinical application of the UF-500i Flow Cytometer in screening the asymptomatic urinary infection of pregnant women. Methods：The leukoeytes and bacteria in 500 mid-stream urine specimens of pregnant women were detected and compared with UF-500i. Results ：The positive rates of UF-500i and urine euhure were 10.4% and 7.6% respectively, and their differences had no statistical significance and kept considerable consistency （ Kappa = 0. 999, P 〉 O. 05 ）. The sensitivity and specificity of the UF-500i detection for urinary infection were 88.4% and 96.9% and the positive and negative predictive value were 73.1% and 98.9% respectively. Conclusions： The UF-500i Flow Cytometer in screening the asymptomatic urinary infection of pregnant women is rapidly, convenient and economical, which has good application value, and the urine contamination must be pay attention to.
