尿液有形成分与尿培养对尿路感染的临床诊断价值分析

Analysis of Clinical Diagnostic Value of Urinary Tract Infection by Urine Formed Element and Urine Culture

目的:评价尿路感染患者应用尿液有形成分与尿培养的诊断价值。方法:选择2019年6月-2021年6月湖北省麻城市人民医院接诊的100例尿路感染患者,均采用尿液有形成分与尿培养诊断,对比尿路感染患者应用尿液有形成分与尿培养诊断的临床应用价值。结果:尿液有形成分检验的阳性率和诊断准确率高于尿培养,差异有统计学意义(P<0.05)。尿培养中共分离致病菌65例,菌群分布:大肠埃希菌41.54%,肺炎克雷伯菌9.23%,铜绿假单胞菌和其他革兰阳性球菌均为7.69%,屎肠球菌和粪肠球菌均为6.15%,腐生葡萄球菌为3.07%,奇异变形杆菌、阴沟肠杆菌、产气肠杆菌、液化沙雷菌、鲍曼不动杆菌、聚团肠杆菌、其他革兰阴性杆菌、荧光假单胞菌、表皮葡萄球菌、草绿色链球菌、金黄色葡萄球菌、真菌均为1.54%。结论:尿路感染患者诊断中应用尿液有形成分检验的诊断准确率高于尿培养,值得在临床中进行推广使用。

Objective:To evaluate the diagnostic value of urine formed element and urine culture in patients with urinary tract infection.Methods:A total of 100 patients with urinary tract infection treated in People's Hospital of Macheng City from June 2019 to June 2021 were selected.All patients were diagnosed by urine formed element and urine culture,and the clinical application value of urine formed element and urine culture for diagnosis of urinary tract infection was compared.Results:The positive rate and diagnostic accuracy of urine formed element test were higher than those of urine culture,with statistical significance(P<0.05).Sixty-five cases of pathogenic bacteria were isolated in urine culture.Flora distribution:Escherichia coli 41.54%,Klebsiella pneumoniae 9.23%,Pseudomonas aeruginosa and other gram-positive cocci 7.69%,Enterococcus faecium and Enterococcus faecalis 6.15%,Staphylococcus saprophyticus 3.07%,Proteus mirabilis,Enterobacter cloacae,Enterobacter aerogenes,Serratia liquefaciens,Acinetobacter baumannii,Enterobacter agglomerans,other gram-negative bacilli,Pseudomonas fluorescens,Staphylococcus epidermidis,Streptococcus viridis,Staphylococcus aureus and fungi 1.54%.Conclusion:The diagnostic accuracy of urine formed element test is higher than that of urine culture in the diagnosis of urinary tract infection,and it deserves clinical promotion and application.
