尿液微晶的成分分析

利用X射线衍射法和傅立叶红外光谱法对16例结石病人和24例正常人尿液微晶进行了对比研究,从尿液抑制剂和尿液微晶在尿路中的滞留等角度分析了尿液微晶和结石形成的关系.结果表明,正常人尿液微粒以结晶态物质为主,其中以磷酸铵镁为主要成分的占66.7%,尿酸为主的占16.7%,一水草酸钙(COM)和β-磷酸三钙混合物为主的占16.7%;在结石病人中,尿液微晶以COM为主要成分的占33.3%,以磷酸八钙为主的占33.3%,以COM和β-磷酸三钙的混合物为主的占16.7%,以β-磷酸三钙和非晶态物质的混合物为主的占16.7%.

Composition analysis of urinary crystallites

Urinary crystallites of 16 lithogenic patients and 24 healthy persons were conparatively investigated by X-ray power diffraction and Fourier transform infrared spectroscopy.The effect of urinary crystallites on formation of urinary stone was discussed.The results showed that most of the particles in urine of healthy persons were crystalline material,and the main composition of urinary crystallites in 66.7% healthy persons was magnesium ammonium phosphate,and that of 16.7% was uric acid,16.7% was a mixture of calcium oxalate monohydrate(COM) and tricalcium phosphate.However,the main composition of urinary crystallites in 33.3% lithogenic patients were COM,33.3% were octacalcium phosphate,16.7% was a mixture of tricalcium phosphate and COM,and 16.7% was a mixture of tricalcium phosphate and amorphous materials.
