Answer

Patients with gout have as much as 1000 times more uric acid in the body as unaffected individuals do and are almost twice (1.97 times) as likely to develop renal stones as healthy individuals are [83] ; therefore, they may have a history of renal colic and hematuria. Indeed, renal stones may precede the onset of gout in 14% of affected patients. Whereas 52% of these patients may have stones composed entirely of uric acid, 20% may develop calcium oxalate or sometimes calcium phosphate stones. [84]
