At the International Kidney Stone Institute, our goal is nothing less than the cure.

Uric Acid Stones


Uric acid is produced when the body metabolizes protein.  Humans have a level of uric acid that is 10 times greater than other mammals.  Urine becomes saturated with uric acid when the pH drops below 5.5.  Individuals are more prone to develop uric acid stones when they ingest large amounts of protein, such as that found in red meat or poultry.  Uric acid stones are also found more commonly in those individuals who have received chemotherapy or suffer from gout.  Rarely, uric acid stones are caused by an inherited disorder of protein metabolism.
