The chemical constituents of 34 feline urinary calculi and five urethral plugs were analysed by infrared spectroscopy. The analysis revealed that 18 (52.9 per cent) of the calculi contained magnesium ammonium phosphate hexahydrate (struvite) as the major component; 10 (29.4 per cent) contained complex ammonium urates (three of them also containing calcium phosphate, mainly on the surface); three were composed of calcium phosphates and three were composed mainly of calcium oxalate mono and dihydrates. The urethral plugs were composed primarily of struvite, but also contained large amounts of organic matter. The examination of 16 selected samples by scanning electron microscopy and electron dispersive x-ray analysis revealed that their crystalline structures were similar to those of canine stones.
采用红外光谱法对34块猫尿结石和5个尿道栓的化学成分进行了分析。分析结果显示，18块（52.9%）结石以六水磷酸镁铵（鸟粪石）为主要成分；10块（29.4%）含有复合尿酸铵（其中3块还含有磷酸钙，主要在表面）；3块由磷酸钙组成，3块主要由一水和二水草酸钙组成。尿道栓主要由鸟粪石组成，但也含有大量有机物。通过扫描电子显微镜和电子色散X射线分析对16个选定样本进行检查，结果显示它们的晶体结构与犬类结石相似。
