The Role of Computed Tomography Findings in Prediction of Stone Composition

Abstract

Hounsfield units (HU) provides a quantitative assessment of stone density in the urogenital tract on non-contrast computed tomography (NCCT) and has the ability to predict treatment success. The difference in HU (HUdiff) value was measured on NCCT in two patients. Our opinion is that HUdiff can predict stone composition before treatment.
