Calcium forms in the bladder primarily through the precipitation of calcium salts when urine becomes supersaturated with calcium and oxalate or phosphate. Factors contributing to this include dehydration, high dietary calcium intake, or metabolic disorders. When these conditions exist, minerals can crystallize and aggregate, leading to the formation of bladder stones or calcifications. This process can be influenced by urine pH and other urinary constituents.
