| 摘 要： | 为了深入了解广东省珠江三角洲尿路结石的组份,为临床的相关研究和预防提供参考,采用X-射线光电子能谱(XPS)和X-射线衍射法(XRD)对6例典型的混合型尿路结石成份和物相进行了分析。结果表明,所检尿石成份合一水草酸钙、二水草酸钙、羟基磷灰石,其中2例含有少量磷酸铵镁。随着尿石中磷酸盐的增加,一水草酸钙(COM)的含量减少,二水草酸钙(COD)含量增加,表明磷酸盐的沉积抑制了高能量的COD向低能量的COM转化。采用XPS和XRD联合分析,可以较为准确地检测尿路结石的组份和物相。

| Abstract: | In order to seek the methods for the prevention and cure of urinary stones in Dongjiang valley in Guangdong province, the chemical constituents and morphology of six mixed urinary stones were analyzed by X-ray photoelectron spectroscopy (XPS) and X-ray powder diffraction (XRD). All of the six stones consisted of calcium oxalate monohydrate (COM), calcium oxalate dihydrate (COD) and hydroxyapatite. Two of them contained little ammonium magnesium phosphate. As increasing the amount of phosphate in urinary stones, the amount of COM decreased and that of COD increased, which indicated that the sediment of phosphates in the stones can inhibit the transformation from high energy COD to low energy COM. Combining XPS and XRD methods, the compositions and phases of urinary stones can be obtained accurately. |
