title: Identification of flumequine in a urinary calculus.
abstract: Various analytical methods are available to help identify the presence of drugs in urinary calculi. Using infrared spectrophotometric analysis, nonmetabolized flumequine was identified in a protein calculus from a patient who had taken the drug for a urinary tract infection. Free flumequine can precipitate in an acidic environment.
