Do We Really Need Kidneys-Ureters-Bladder Radiography to Predict Stone Radiopacity Before Treatment with Shockwave Lithotripsy? Development and Internal Validation of a Novel Predictive Model Based on Computed Tomography Parameters

摘要

Purpose: To produce and validate a predictive model based on CT parameters for calculating the probability of a stone to be visible on fluoroscopy of shockwave lithotripsy (SWL) and to compare its accuracy to that of kidneys-ureters-bladder (KUB) radiography.
