摘要
目的探讨尿沉渣细菌定量计数能否作为尿路感染的一项快速筛查指标。方法以UF-1000i全自动尿沉渣定量分析仪和尿液细菌培养对医院246例尿液标本进行检测并且对检测结果进行统计分析和比较。结果 246例尿液标本中,尿沉渣细菌计数阳性50例,阳性率为20.3%,阴性196例,阴性率为79.7%;尿液细菌培养阳性54例,阳性率为21.9%,阴性192例,阴性率为78.1%。两者差异无统计学意义(P>0.05)。以尿液细菌培养结果为参照标准,尿沉渣细菌定量检测的敏感度为52.0%,特异度为85.7%,准确率为78.9%,阳性预测值为48.1%,阴性预测值为87.5%。结论尿沉渣细菌定量计数可作为尿路感染的一项快速筛查指标,但不能作为尿路感染的确诊指标。
Objective To investigate whether the quantitative bacterial count can be used as a rapid screening method for urinary infection.Methods Quantitative bacterial count of urinary sediment analyzed by UF-1000 and bacterial culture results of 246 urine samples were retrospectively studied and compared.Results The positive rate for urine sediment bacteria counts was 20.3%（50/246）,while the negative rate was 79.7%（196/246）;the positive rate for urinary bacterial culture was 21.9%（54/264）,while the negative rate was 78.1%（192/246）.Took urinary culture results as a reference standard,the sensitivity of quantitative bacterial count of urinary sediment was 52.0%,the specificity was 85.7%,the accuracy 78.9%,the positive predictive value was 48.1%,and the negative predictive value was 87.5%.Conclusion Quantitative bacterial count of urinary sediment could be used as a rapid screening methord for urinary tract infection,but can′t be used to make a definite diagnosis.
