尿干化学分析及尿液沉渣检查对尿路感染诊断价值对比

Comparison of Diagnostic Value of Urine Dry Chemical Analysis and Urine Sediment Test for Urinary Tract Infection

目的:探讨尿干化学分析与尿液沉渣检查对尿路感染诊断的价值。方法:选我院尿路感染患者80例。随机分两组各40例,对照组尿干化学分析法,实验组尿液沉渣检查法分析,观察检测结果。结果:采用镜下检查准确率为81.7%,其次为计数检查(WBC)诊断准确率为75.3%,亚硝酸盐(NIT)检查诊断正确率为71.5%,计数检查(WBC)或亚硝酸盐(NIT)准确率为76.9%。结论:在大规模尿路感染检查时,尿干化学分析可作为第一步诊断方案,若检查结果出现问题可采用尿沉渣显微镜观察作为第二步诊断,对于明显阳性患者标本需要进一步病原体分离、培养、鉴定及药敏实验,但尿培养仍然是尿路感染诊断的最重要标准。

Objective:To investigate the value of urine dry chemical analysis and urine sediment examination in the diagnosis of urinary tract infection.Methods:Eighty patients with urinary tract infection in our hospital were selected.They were randomLy divided into two groups.The control group and the experimental group each had 40 cases.The control group was analyzed by urine dry chemical analysis,and the experimental group was analyzed by urine sediment test.The test results were observed.Results:The accuracy of microscopic examination was 81.7%,followed by the diagnostic accuracy of count examination(WBC)of 75.3%,and the diagnostic accuracy of nitrite(NIT)examination was 71.5%.Counting examination(WBC)or nitrite(The accuracy rate of NIT)is 76.9%.Conclusion:For obvious positive patients,further pathogen isolation is required.Culture,identification and susceptibility testing,but urine culture is still the most important criterion for the diagnosis of urinary tract infection.
