尿石成分红外光谱分析(附500例报告)

Analysis urinary stones by infrared spectroscopy

目的和方法：介绍红外光谱尿石成分分析方法以及500例尿石成分分析结果。结果：最常见的尿石成分是一水草酸钙（63％），其次是羟基磷灰石（31％），二水草酸钙（15％），尿酸占11％，六磷酸镁铵（5％）和碳酸磷灰石（2％）较少见。结论：文中讨论了红外光谱分析原理，以及尿石成分与年龄、性别的关系。

Objective and methods: To introduce the mothed of urinary stone analysis byinfrared (IR) spectroscopy and the results of 500 urinary calculi analysis. Results: The most commoncomponent was calcium oxalate monohydrate (COM) 63%, followed by hydroxyapatite (HAD)31 %, calcium oxalate dihydrate 19%, un cacid 11%, struvite 5% and carbonate apatite 2%Conclusions: The principle of IR spectroscopy and the relations between component of stone andage and sex were discussed.
