title: [Study of oval crystals in urine].
abstract: Urinary crystals were collected by repeated centrifugation from two outpatients with calcium oxalate crystalluria where oval forms predominated and were studied by scanning electron microscopy and X-ray diffraction. Fibrous structure, biconcave surface and prismatic appearance of oval crystals were shown. The side view of oval forms may be prismatic X-ray diffraction patterns of urinary crystals indicated that oval crystals consist of calcium oxalate monohydrate.
