细针针吸细胞学诊断痛风结节临床应用

Fine needle aspiration cytologic examination in diagnosis of gout calculi

目的探讨痛风结节的细针针吸活组织检查细胞学特点，以提高临床诊断准确率。方法对12例痛风结节的细针针吸活组织检查细胞学特点、血尿酸以及组织病理学资料进行回顾分析。结果经组织病理学检查及临床治疗证实为痛风的12例病例中，细针针吸细胞学检查诊断为痛风结节12例，诊断准确率为100％。12例病例中10例血尿酸值高于正常值（90—420μmol／L）范围，2例在正常值范围高界。结论进一步加强对痛风结节的细胞学特点的认识，有利于提高痛风结节诊断的准确率。

Objective To study the characteristics of the fine needle aspiration cytology of gout calculi. Methods The clinical records of 12 cases were reviewed with respects to cytopathology and blood chemistry. Results In the 12 cases of gout calculi, all cases were diagnosed accurately by fine needle aspiration cytology. The accuracy rate of fine needle aspiration cytology was 100%. The level of blood uric acid was higher than normal （90 to 420 μmol/L） in 10 of the 12 cases, with that of the other two at the upper limit. Conclusion Better acquaintance of the cytology helps to improve the rate of accuracy in the diagnosis of gout calculi.
