摘要
肾脏疾病是全球范围内重要的公共卫生问题，早期诊断对改善预后具有关键意义。本研究旨在评估尿液分析在肾脏疾病诊断中的准确性，并探索其作为无创筛查工具的潜力。通过回顾性分析2018年至2023年间500例疑似肾脏疾病患者的临床数据，采用多参数尿液检测技术结合生物标志物分析，与金标准肾活检结果进行对比验证。结果显示，尿液分析在检测蛋白尿、血尿及特定代谢产物方面表现出较高的敏感性和特异性，综合准确率可达87.4%。此外，研究首次提出基于人工智能算法的尿液特征模式识别模型，显著提高了复杂病例的诊断效能。结论表明，尿液分析作为一种快速、经济且非侵入性的方法，在肾脏疾病的早期筛查和辅助诊断中具有重要价值，为临床实践提供了新的思路和技术支持。关键词：肾脏疾病；尿液分析；早期诊断；生物标志物；人工智能算法
Accuracy of Urine Analysis in the Diagnosis of Kidney Diseases
Abstract
Kidney diseases represent a significant public health issue globally, and early diagnosis plays a critical role in improving prognosis. This study aimed to evaluate the accuracy of urine analysis in diagnosing kidney diseases and to explore its potential as a non-invasive screening tool. A retrospective analysis of clinical data from 500 patients suspected of having kidney diseases between 2018 and 2023 was conducted, utilizing multiparametric urine testing combined with biomarker analysis, which was validated against the gold standard of renal biopsy results. The findings demonstrated that urine analysis exhibited high sensitivity and specificity in detecting proteinuria, hematuria, and specific me tabolic products, with an overall accuracy rate of 87.4%. Furthermore, this study proposed for the first time a urine feature pattern recognition model based on artificial intelligence algorithms, which substantially enhanced diagnostic performance in complex cases. The conclusion highlights that urine analysis, as a rapid, cost-effective, and non-invasive method, holds important value in the early screening and auxiliary diagnosis of kidney diseases, providing new insights and technical support for clinical practice.
