PURPOSE: We determined whether the biochemical and physicochemical backgrounds of
patients with brushite stones differ from those with hydroxyapatite and calcium oxalate
stones. MATERIALS AND METHODS: From a computer data base of patients completing
ambulatory evaluation 19 with brushite stones, 24 with hydroxyapatite stones and 762 with
