title: Urinary calculus during methazolamide therapy.
abstract: A 68-year-old white man with Paget's disease and open-angle glaucoma was treated with methazolamide, 50 to 100 mg three times daily. Ten months after the medication was initiated he developed ureteral colic and a calcium oxalate stone was surgically removed. Three months after the drug was reinstituted the patient passed three calcium phosphate stones. This suggested a casual relationship between methazolamide and stone formation, although renal calculi also complicate Paget's disease and acetazolamide had been administered briefly.
