Jf. Sabot et al., ANALYSIS OF URINARY CALCULI CONTAINING TRIAMTERENE - PRESENCE OF A GLUCURONIC METABOLITE, Analytical letters, 29(8), 1996, pp. 1319-1327
Urinary calculi containing triamterene were described since 1979. We h
ave studied calculi, obtained from an anuric patient, by surgery. This
paper describes the advanced techniques that were used, such as infra
red spectroscopy, nuclear magnetic resonance, mass spectrometry associ
ated with thin-layer chromatography or gas chromatography, to show the
presence of unusual compounds. Six metabolites are found, among them
pure triamterene (96%), hydroxy-triamterene, and a particular metaboli
te containing glucuronic acid.
