Evaluating Kidney Stones and if they Lead to Kidney Disease


About this study

The purpose of this study is to gather information that will be used to improve CT imaging techniques such that they may more accurately identify the type of stone present in the kidney. The overall goal of this research is to learn what causes kidney stones to form and determine if kidney stones lead to loss of kidney function or kidney disease.
