| Research Abstract |
Urinary calculi were embedded in polyester resin and thin sections (about 30 mum) were prepared with microtome. These sections were examined by micropolariscope and these images were quantitatively estimated by image-analyzer. The ratios of monohydrate dihydrate of calcium oxalate (COM / COD) were apploximatety similar to these estimated by X-ray diffraction and scanning electron microscopy. The ratios of calcium oxalate / calcium phosphate were also similar to these estimated by infrared spectroscopy and scanning electron microscopy, except of a few cases. But the amorphous substances in the urinary stones, such as apatite or organic matrix, and some crystals, such as hydroxyl-apatite or carbonate-apatite, which are hardly determined under micropolariscope, were impossible to estimate quantitativelyby the present method of image-analysis.
