尿干化学分析联合血清PCT、CRP检测在尿路感染诊断中的应用价值

Application Value of Urine Dry Chemistry Analysis Combined with Serum PCT and CRP Detection in Diagnosis of Urinary Tract Infections

目的:分析尿干化学分析联合血清降钙素原(PCT)、C反应蛋白(CRP)检测在尿路感染诊断中的应用价值。方法:选取2022年11月—2023年8月常州市德安医院收治的疑似尿路感染患者88例作为研究对象,均接受尿干化学分析及血清PCT、CRP检测。以中段尿培养结果作为“金标准”,分析尿干化学分析与血清PCT、CRP检测的诊断效能。结果:88例疑似尿路感染患者中确诊73例;尿干化学分析与血清PCT、血清CRP诊断及三项联合诊断的灵敏度比较,差异无统计学意义(P>0.05);尿干化学分析联合血清PCT与CRP诊断的特异度高于三项单独诊断,尿干化学分析联合血清PCT与CRP诊断的准确性高于血清PCT、血清CRP检测,差异有统计学意义(P<0.05)。结论:尿干化学分析联合血清PCT、CRP检测诊断尿路感染的效果显著,能够提高诊断准确性与特异度。

Objective:To analyze the application value of urine dry chemistry analysis combined with serum procalcitonin(PCT)and C-reactive protein(CRP)detection in the diagnosis of urinary tract infections.Methods:A total of 88 suspected patients with urinary tract infections admitted to Changzhou De'an Hospital from November 2022 to August 2023 were selected as the study subjects.All patients underwent urine dry chemistry analysis and serum PCT and CRP detection.The results of mid-stage urine culture were as the gold standard to analyze the diagnostic efficiency of urine dry chemistry analysis and serum PCT and CRP detection.Results:Among the 88 suspected patients with urinary tract infections,73 cases were confirmed;There was no statistically significant difference in the sensitivity of urine dry chemistry analysis,serum PCT,CRP and the three-item combined diagnoses(P>0.05).The specificity of urine dry chemistry analysis combined with serum PCT and CRP was higher than that of the three separate diagnoses,and the accuracy of urine dry chemistry analysis combined with serum PCT and CRP was higher than that of serum PCT and serum CRP,and the difference was statistically significant(P<0.05).Conclusion:The combination of urine dry chemistry analysis and serum PCT and CRP detection in the diagnosis of urinary tract infections has a significant effect,and can improve diagnostic accuracy and specificity.
