微X线衍射法在泌尿系结石检测中的临床研究

X-ray microdiffraction in the clinical application of urolithiasis

目的:探讨泌尿系结石成分的分析方法,分析我院〔编者按:单中心研究结果不能作为本地区的数据来源,只能略见一斑〕泌尿系结石的主要化学成份及其防治方法。方法:采用X线衍射法对我院随机取样的48枚人体泌尿系统结石标本成分进行定性和定量分析。结果:我院泌尿系结石以结晶态物质为主,其中草酸钙结石占65%,尿酸结石占35%;草酸钙结石中大都含有磷酸盐,但含量通常小于18%。结论:草酸钙、尿酸和磷酸盐构成了我院泌尿系结石的主要成分,采用微X线衍射法可以较为准确地检测泌尿系结石的化学组份和物相。

Objective. To investigate the prevention and cure of urinary stones in Shenzhen by analyzing the composition of urinary stones. Method： From July 2012 to July 2013, 48 random urinary stones were quantitatively and morphologically analyzed by X-ray microdiffraction. Result：Calcium oxalate was the main composition of urina- ry stones （65%） in Shenzhen, while 35% were uric acid stones. Most calcium oxalate stones contained phos- phate, but its content usually was less than 18%. Conclusion： Calcium oxalate, uric acid and phosphate are the main compositions of urinary stones in Shenzhen. The compositions and phases of urinary stones can be obtained accurately by X-ray microdiffraction.
