'''尿液中尿酸溶解度下降和过饱和化形成的结石'''

尿酸结石是尿液中尿酸溶解度下降和过饱和化形成的。

大量尿酸结晶沉积关节腔内，可诱发[[痛风性关节炎]]。患者往往在深夜突然出现关节疼痛，呈撕裂样、刀割样疼痛，严重时影响走路，伴关节红肿，局部皮肤温度升高。首次发作以第一跖趾关节（大脚趾与脚掌连接的关节）最常见，占90%左右，踝关节、膝关节、腕关节、指间关节等也会受累。如果饮用随低食物把尿酸控制好，痛风就不会反复发作，否则大量尿酸结晶沉积在皮下、关节腔内，会形成痛风石，造成关节骨质破坏、畸形。<ref>[https://baike.baidu.com/reference/8655076/0090yev7wca_BgK7Wp1Guvnsy09bKyGjwguXQB2FGBpa01fus-Nhnw8HLrkeLJs87ZImDBkrUUsqnYvtPSZ4BKj5Fl4do98AOGTXP6yYT65JVJBfKeCFZm8kYw  人民网，引用日期2022-07-30] </ref>
