Uroliths containing 70% or greater silica comprise approximately 1% of the canine uroliths submitted to the Minnesota Urolith Center. Male dogs are far more commonly affected than females. In our series, 84 different breeds were affected. Currently available data suggest dietary factors play a role in their formation. Diagnosis is facilitated by the characteristic jackstone configuration of silica uroliths, but must be confirmed by quantitative analysis. Voiding urohydropropulsion or surgery are currently the most practical methods of removal of silica uroliths.
二氧化硅含量达到或超过70%的尿石约占提交至明尼苏达尿石中心的犬类尿石的1%。公犬比母犬更易受影响。在我们的病例系列中，涉及84个不同品种。目前可得的数据表明饮食因素在其形成过程中起作用。二氧化硅尿石特有的“小石子”形态有助于诊断，但必须通过定量分析来确诊。目前，排尿式尿液压推注或手术是清除二氧化硅尿石最实用的方法。
