title: [A case of silicate urolithiasis].
abstract: We report a case of silicate calculi with no history of taking magnesium trisilicate. A 33-year-old woman was sent to our hospital as an emergency case because of severe right lower flank pain. Physical examination was unremarkable except for severe right cost-vertebral angle knock pain. She denied administration of a magnesium trisilicate anti-acid before. She was admitted to the urologic ward since the pain did not relieve in spite of several analgesics. The stone passed spontaneously on the third hospital day. Analysis by infrared spectrophotometry demonstrated the composition to be over 98% of silicate. A review of the literatures discloses only 21 cases of silicate stones.
