Sodium urate accelerates precipitation of calcium oxalate in vitro.
Precipitation of calcium oxalate crystals from a metastable solution can be detected within 10 min if crystalline sodium urate is added at a solid to liquid ratio of 0.1 mM or more. Without urate, precipitation begins after 50 min. Uric acid is not effective. Pyrophosphate inhibits the effects of sodium urate.
