Morphology and phase composition of urinary calculi.

Abstract

Forty seven urinary calculi were examined by means of X-ray powder diffraction (including both the Debye-Scherrer technique and powder diffractometer study) and infrared spectroscopy in order to determine their phase composition. The stones were collected in the period of two years from patients in Southern Poland, most of them consisting of calcium oxalate monohydrate as the only one or one of the few components.
