Abstract

Objective To study the clinical effect of dry chemical method combined with urinary sediment in routine urine examination. Methods From January 2018 to October 2018, 200 patients with suspected urinary tract infection who underwent routine urine examination in the Traditional Chinese Medicine Hospital of Yuyao were selected for prospective study, and fresh morning urine samples were collected from 200 patients.Urine samples were detected by urine dry chemistry analyzer and urine sediment analyzer respectively, and the urine routine indicators of urine dry chemistry method and urine sediment method were compared.According to the results of urine bacterial culture, the sensitivity, specificity and accuracy of urine dry chemical method, urine sediment method and urine dry chemical method for the diagnosis of urinary tract infection were calculated and compared.Then, the consistency test was used to analyze the consistency of results of urine dry chemistry method, urine sediment method, urine dry chemical method+ urine sediment method with urine bacterial culture. Results (1)There were no statistically significant differences between the results of urine dry chemical method and urine sediment method on the urine red blood cell, white blood cell, transparent tube type and other indicators (t=0.562, 0.343, 0.901, all P>0.05). (2)Among 200 suspected patients with urinary tract infection, 157 patients were confirmed to have urinary tract infection by urine bacterial culture, and the remaining 43 patients had no urinary tract infection.The sensitivity, specificity, accuracy of urine dry chemistry method and urine sediment method in the diagnosis of urinary tract infection had no statistically significant differences (χ2=0.120, 0.081, 0.022, all P>0.05). But the sensitivity, specificity, accuracy of urine dry chemistry method + urine sediment method in the diagnosis of urinary tract infection were 96.18%, 97.67%, 96.50%, respectively, which were higher than those of the urine dry chemistry method and urine sediment method (χ2=6.497, 6.081, 11.923, 8.219, 4.962, 12.858, all P<0.05). According to the consistency analysis, the diagnosis results of urinary tract infection by urine dry chemical method and urine sediment method were in good consistency with the results of urine bacterial culture, with the Kappa value of 0.854, while the consistency of urine dry chemical method, urine sediment method with the urine bacterial culture results were all moderate, with the Kappa value of 0.642 and 0.637, respectively. Conclusion The combination of urine dry chemical method and urine sediment method can improve the accuracy of urine routine examination and improve the value of urine routine examination in the diagnosis of urinary tract infection.

干化学法与尿沉渣法联合应用于尿常规检查的临床观察

目的探讨干化学法结合尿沉渣法进行尿常规检查的临床效果。方法选择2018年1月至2018年10月在余姚市中医院接受尿常规检查的200例疑似尿路感染患者进行前瞻性研究，采集200例患者晨尿新鲜样本。分别用尿液干化学分析仪和尿沉渣分析仪检测尿液样品，并对尿液干化学法和尿沉渣法的尿常规指标进行比较。根据尿液细菌培养结果，计算并比较了尿液干化学法、尿液沉淀法和尿液干化学方法诊断尿路感染的敏感性、特异性和准确性。然后，通过一致性检验，分析尿液干化学法、尿液沉淀法、尿液干化学方法+尿液沉淀法与尿液细菌培养结果的一致性。结果（1）尿液干化学法和尿液沉淀法在尿红细胞、白细胞、透明管型等指标上的结果无统计学意义（t=0.562、0.343、0.901，均P>0.05），157名患者经尿液细菌培养证实有尿路感染，其余43名患者无尿路感染。尿干化学法和尿沉渣法诊断尿路感染的敏感性、特异性、准确性无统计学意义（χ2=0.120、0.081、0.022，均P>0.05），而尿干化学+尿沉渣法对尿路感染诊断的敏感性、特异性、准确性分别为96.18%、97.67%、96.50%，分别高于尿液干化学法和尿液沉淀法（χ2=6.497、6.081、11.923、8.219、4.962、12.858，均P<0.05），Kappa值为0.854，而尿液干化学法、尿液沉淀法与尿液细菌培养结果的一致性均为中等，Kappa值分别为0.642和0.637。结论尿干化学法与尿沉渣法相结合，可提高尿常规检查的准确性，提高尿常规检测在尿路感染诊断中的价值。关键词：尿路感染；尿常规；体检；尿液干化学；尿液沉淀法；诊断；红细胞；白细胞；透明质管类型
