Twenty-four hour urine specimens from 26 active stone formers and 15 non-stone formers were passed through an ultrafilter that retained all molecules with a molecular weight greater than 50,000. Microscopic spherical bodies that laked alizarin red were observed in the urinary ultrafiltrate from 24 of 26 active stone formers. Only three of 15 non-stone-forming control urines contained these bodies. Histochemical studies showed the presence of calcium, phosphorus, and carbohydrate-protein complexes. No crystalline elements were detected.
收集了26名活动性结石形成者和15名非结石形成者的24小时尿液样本，使其通过一个超滤器，该超滤器可保留所有分子量大于50,000的分子。在26名活动性结石形成者中的24人的尿液超滤液中观察到了使茜素红褪色的微观球形体。15名非结石形成对照者的尿液中只有3份含有这些球形体。组织化学研究显示存在钙、磷和碳水化合物 - 蛋白质复合物。未检测到结晶成分。
