目的:探讨尿沉渣白细胞及细菌定量计数联合检测与尿细菌培养诊断尿路感染一致性。方法:选取我院2012年1月-2013年12月320例疑似尿路感染患者,对其尿液标本予以检测,研究组应用尿液沉渣白细胞及细菌定量计数检验,对照组则实施尿液细菌培养进行诊断,将细菌培养作为金标准,分析两种诊断效果。结果:尿液细菌培养作为金标准情况下,研究组检测灵敏度97.3%,特异度95.4%,阳性预测值96.9%,阴性预测值96.1%,阳性似然比21.14,阴性似然比0.041。结论:尿沉渣白细胞及细菌定量计数联合检测可以快速有效筛查出疑似尿路感染患者,结果具有较高准确性,值得临床推广应用。 Objective: To investigate the urine sediment leucocyte and bacterial count combined detection and urine bacterial culture diagnosis of urinary tract infection consistency. Methods: A total of 320 patients with suspected urinary tract infection from January 2012 to December 2013 in our hospital were enrolled in this study. Urinary samples were detected in the study group. Urinary sediment leukocytes and bacteria were counted in the study group while urine in the control group Culture for diagnosis, bacterial culture as a gold standard, analysis of two diagnostic results. Results: In the case of urinary bacterial culture, the sensitivity of the study group was 97.3%, the specificity was 95.4%, the positive predictive value was 96.9%, the negative predictive value was 96.1%, the positive likelihood ratio was 21.14 and the negative likelihood ratio was 0.041. Conclusion: Combined detection of urinary sediment leucocyte and bacterial count can rapidly and effectively screen suspected urinary tract infection patients with high accuracy, which is worthy of clinical application.
