尿干化学与尿沉渣联合检测在泌尿系统疾病筛查中的临床价值分析

Objective To investigate the clinical application value of combined urine dry chemistry and urinary sediment testing in the screening of urinary system diseases, to compare the diagnostic performance of single-test versus combined-test modalities, and provide a clinical basis for rapid and accurate screening of urinary system disorders. Methods A retrospective study was conducted involving 200 patients with suspected urinary system diseases admitted to the nephrology and urology departments of our hospital from January 2024 to June 2025. All subjects underwent both urine dry chemistry and urinary sediment testing simultaneously. The results of these tests as well as combined testing were statistically analyzed, with clinical comprehensive diagnosis and 6-month follow-up outcomes serving as gold standards to evaluate the diagnostic performance of each method. Results The combined testing demonstrated significantly higher sensitivity and accuracy compared to either single test method(P<0.05). Although the specificity of combined testing showed a slight decrease, this difference was not statistically significant(P>0.05). The consistency between urine dry chemistry and urinary sediment testing was moderate(kappa=0.58). Conclusion The integrated approach combining rapid urine dry chemistry screening with precise identification of urinary sediment components offers dual advantages in enhancing the accuracy and diagnostic efficacy of urinary system disease screening. It comprehensively reflects abnormalities in urine physicochemical properties and cellular components, it can provide a reliable detection plan for clinical screening of urinary system diseases.
