Development of a Scoring System From Noncontrast Computerized Tomography Measurements to Improve the Selection of Upper Ureteral Stone for Extracorporeal Shock Wave Lithotripsy

Abstract

Stone volume, mean stone density and skin-to-stone distance were potential predictors of the successful treatment of upper ureteral stones with shock wave lithotripsy. A scoring system based on these 3 factors helps separate patients into outcome groups and facilitates treatment planning.
