Xanthine urolithiasis: ultrastructure analysis of renal and bladder calculi.
The surface structure of a xanthine stone from a patient with hereditary xanthinuria was examined using scanning electron microscopy. This revealed that the xanthine stone was composed of at least two very different structures. One was a spherical protrusion with craters and a fine granular surface and the other consisted of a granular growth of plate-like crystals.
