Brief Summary

Brushite kidney stones are a unique form of calcium phosphate stones that have a tendency to recur quickly if patients are not aggressively treated with stone prevention measures. Little research has been undertaken to better understand the clinical history and potential urinary abnormalities that may predispose one to these troublesome kidney stones.
