Objective: Uric acid is a kind of end product of purine metabolism extrinsic source and endogenous, it's dissolvability and degree of saturation in the blood is limited, the maximum degree of saturation is 416μmol/L, crystal will emerge when surpass this density. About 25% of uric acid excrete through digestive canal, the rest through kidney, the condition of it's egestion through kidney roughly as follows:(1) Almost 100% of the blood uric acid is filtered through the glomcrulus;(2)98%～100% of the uric acid which is filtered will be reabsorb in the proximate nephric tubule;(3) The nephric tubule initiatively secrete uric acid to the lumens of nephric tubule;(4) Part of the secreted uric acid will be reabsorbed to the blood around the nephric tubule.
