Kidney Stones: Diagnostic and Treatment Strategies .
Calcium stone formation begins with formation of calcium phosphate deposits (Randall plaques) on the external urothelial surface of the papilla. Hence, calcium oxalate stones typically have a small component of calcium phosphate (apatite or brushite). If small particles were not anchored to these plaques, they would simply wash into the urine.
