In 3,000 calculi, monosodium urate was detected in 50 cases (1.66%). Infrared frequencies of monosodium urate are reported. In thin sections it appeared as long and thin fan-shaped or feather-like arranged crystals. Six calculi had monosodium urate as the sole component but all other cases were of mixed composition, with whewellite as the main secondary substance. The relative scarcity of monosodium urate cannot be explained by its high aqueous solubility because in urine the solubility decreases with increasing sodium concentration. Monosodium urate should be suspected in radiolucent calculi with neutral or light alkaline reaction and high uric acid and sodium concentrations in the patient's urine.
在3000颗结石中，检测到50例（1.66%）含有尿酸钠。报告了尿酸钠的红外频率。在薄片中，它呈现为细长的扇形或羽毛状排列的晶体。6颗结石以尿酸钠为唯一成分，但所有其他病例均为混合成分，以草酸钙为主要次要物质。尿酸钠相对稀少不能用其高水溶性来解释，因为在尿液中其溶解度会随着钠浓度的增加而降低。对于透X线结石，若患者尿液呈中性或轻度碱性反应，且尿酸和钠浓度较高，则应怀疑含有尿酸钠。
