In this study, gall stones from 45 patients were analyzed in vitro. Gall stones from 23 patients were cholesterol stones and the others were non-cholesterol. Correlation with each radiologic physical properties(the number of stones, shape, calcification pattern, Hounsfield units measured by computed tomography) and chemical composition(cholesterol or non-cholesterol) were analyzed. The results revealed that the numbers and size were not related to the chemical composition, but there were significant correlation with faceted stones(p=0.002) or stones with no calcification (p=0.010) and cholesterol composition, and with irregular stones(p=0.000) or stones with dense calcification(p=0.015) and non-cholesterol composition. In study of Hounsfield units, it was difficult to fix the boundary, but the difference between cholesterol composition(138.43±281.81) and non-cholesterol composition(404.32±306.06)was significant(p=0.0109).
