Infrared spectroscopic analysis of 741 canine urinary calculi revealed that struvite stones, 58% of the total, were the ones most commonly to be found. Cystine stone disease, 21%, is also of great significance for dogs, whereas calcium oxalate, urate and brushite calculi occur only seldom. 3 cases of xanthine stone formation were also noted. SEM examination revealed structures similar to human stones such as bipyramidal weddellite, pseudomorphs from whewellite to weddellite, apatite deposits in cystine stones and characteristic mono-ammonium-urate needles. Other, unknown, structures were also discovered such as closely-knit intergrowths of cystine and brushite strata, mono-Na-urate and mono-K-urate intergrowths and Ca-urate. Of particular interest are the various forms of xanthine from compact spherical to lance-shapes in sheath-like arrangement.
对741颗犬类尿结石进行红外光谱分析发现，磷酸铵镁结石占总数的58%，是最常见的结石类型。胱氨酸结石病占21%，对犬类也具有重要意义，而草酸钙、尿酸盐和透钙磷石结石则很少出现。还发现了3例黄嘌呤结石形成的病例。扫描电子显微镜检查揭示了与人类结石相似的结构，如双锥状的水草酸钙石、从一水草酸钙石到水草酸钙石的假晶、胱氨酸结石中的磷灰石沉积物以及特征性的尿酸一铵针状物。还发现了其他未知结构，如胱氨酸和透钙磷石层紧密交织生长、尿酸一钠和尿酸一钾共生以及尿酸钙。特别有趣的是各种形态的黄嘌呤，从紧密的球形到鞘状排列的 lance 形。
