A Review on Clinical Application Research of Urinary Crystals

摘要: 目的：为尿结晶在临床实践中的规范化应用提供理论依据与实践参考，提升其在疾病诊疗中的落实性与精准度，挖掘尿结晶从病理标志物到疾病预警、风险量化评估的临床价值延伸路径，填补当前研究中结晶与疾病关联的量化分析空白。方法：结合近年来国内外相关研究进展，系统阐述尿结晶的分类与形成机制，梳理其在各类疾病中的临床应用要点，分析当前检测技术的优势与不足，重点探讨尿结晶与疾病发生发展的量化关联、关键调控机制及临床转化的核心难点，探讨其临床应用的现存问题及发展趋势。结果：尿结晶是尿液中溶解物质在特定条件下析出的固体颗粒，其形成与机体代谢、泌尿系统功能、饮食及药物使用密切相关；其类型、形态、数量、分布特征及动态变化规律，与疾病的发生风险、病程进展、治疗反应存在明确的量化关联，且结晶异常往往早于传统生化指标改变，可作为疾病早期预警的敏感标志物。结论：尿结晶可作为反映机体生理与病理变化的重要“窗口”，规范其临床应用可助力疾病精准诊疗，当前检测技术仍有提升空间，未来需构建“结晶特征–机体表型–疾病谱系”多维度关联体系，推动尿结晶从形态学识别向定量型、预测型临床指标转化，深化结晶形成机制研究以提供临床干预靶点。

Abstract: Objective: To provide a theoretical basis and practical reference for the standardized application of urinary crystals in clinical practice, improve the implementation and accuracy in disease diagnosis and treatment, and explore the extended clinical value path of urinary crystals from pathological markers to disease early warning and risk quantitative assessment. Methods: Combined with the relevant research progress at home and abroad in recent years, this paper systematically elaborates on the classification and formation mechanism of urinary crystals, sorts out the key points of their clinical application in various diseases, analyzes the advantages and disadvantages of current detection technologies, focuses on discussing the quantitative correlation between urinary crystals and disease occurrence and development, and probes into the existing problems and development trends of their clinical application. Results: Urinary crystals are solid particles precipitated when dissolved substances in urine exceed their solubility under specific conditions, and are one of the core contents of urinary formed component examination. Their formation is closely related to the body’s metabolic state, urinary system function, dietary structure and drug use; there is a clear quantitative correlation between their type, morphology, quantity, distribution characteristics and dynamic change rules and the occurrence risk, disease progression and treatment response of diseases. They have important clinical value in the early screening, etiological diagnosis, stratified disease monitoring and individualized treatment guidance of various diseases. Moreover, crystal abnormalities often precede changes in traditional biochemical indicators and can be used as sensitive markers for early disease warning. Conclusion: Urinary crystals can be used as an important “window” reflecting the physiological and pathological changes of the body. Standardizing their clinical application can help improve the accuracy of disease diagnosis and treatment. The current detection technologies still have room for improvement. In the future, it is necessary to construct a multi-dimensional correlation system of “crystal characteristics-organism phenotype-disease spectrum”, promote the transformation of urinary crystals from morphological identification to quantitative and predictive clinical indicators, and deepen the research on crystal formation mechanisms to provide clinical intervention targets.
