中文摘要：目的观察分析细菌定量计数联合尿沉渣白细胞检验在尿路感染诊断中的应用价值.方法 200 例疑似尿路感染患者,均接受细菌定量计数、尿沉渣白细胞检验及尿细菌培养.分析尿细菌培养结果,以尿细菌培养为金标准,比较细菌定量计数、尿沉渣白细胞单一检验及联合检验的诊断效能.结果 200 例疑似尿路感染患者经尿细菌培养诊断,阳性标本为 104 例,阳性率为 52.00%.以尿细菌培养为金标准,联合检验对尿路感染的诊断敏感性、特异性、阳性预测值及阴性预测值分别为 98.08%、96.88%、97.14%、97.89%,细菌定量计数检验对尿路感染的诊断敏感性、特异性、阳性预测值及阴性预测值分别为 80.77%、69.79%、74.34%、77.01%,尿沉渣白细胞检验对尿路感染的诊断敏感性、特异性、阳性预测值及阴性预测值分别为 91.35%、92.71%、93.14%、90.82%,联合检验对尿路感染的诊断敏感性、特异性、阳性预测值及阴性预测值均高于细菌定量计数检验,敏感性、阴性预测值高于尿沉渣白细胞检验(P<0.05).结论在尿路感染诊断中,应用细菌定量计数联合尿沉渣白细胞检验的结果与尿细菌培养更相近,具有较高的诊断价值.

外文标题：Analysis of the application value of quantitative bacterial count combined with urinary sediment leukocyte test in the diagnosis of urinary tract infection

外文摘要：Objective To observe and analyze the application value of quantitative bacterial count combined with urinary sediment leukocyte test in the diagnosis of urinary tract infection.Methods All 200 patients with suspected urinary tract infection were subjected to quantitative bacterial count,urinary sediment leukocyte test and bacterial culture of urine.The results of urinary bacterial culture were analyzed,and the diagnostic efficacy of quantitative bacterial count and urinary sediment leukocyte test alone and in combination were compared using bacterial culture as the gold standard.Results 200 patients with suspected urinary tract infection were diagnosed by urinary bacterial culture,and 104 cases were positive,with a positive rate of 52.00%.Using bacterial culture of urine as the gold standard,the diagnostic sensitivity,specificity,positive predictive value and negative predictive value of joint test for urinary tract infection were 98.08%,96.88%,97.14%and 97.89%,respectively.The diagnostic sensitivity,specificity,positive predictive value and negative predictive value of quantitative bacterial count for urinary tract infection were 80.77%,69.79%,74.34%and 77.01%,respectively.The diagnostic sensitivity,specificity,positive predictive value and negative predictive value of urinary sediment leukocyte test for urinary tract infection were 91.35%,92.71%,93.14%and 90.82%,respectively.The diagnostic sensitivity,specificity,positive predictive value and negative predictive value of joint test for urinary tract infection were higher than those of quantitative bacterial count test,and the sensitivity and negative predictive value were higher than those of urinary sediment leukocyte test(P<0.05).Conclusion In the diagnosis of urinary tract infection,the application of quantitative bacterial count combined with urine sediment leukocyte test is more similar to urine culture,and has high diagnostic value.
