Abstract

INTRODUCTION: "Kidney Stone Calculator" (KSC) helps to plan flexible ureteroscopy, providing the stone volume (SV) and an estimated duration of laser lithotripsy (eLD). eLD is calculated from in vitro ablation rates and SV. KSC's accuracy has been demonstrated with a mean difference between eLD and effective LD (EfLD) of 18.8%. We aimed to reduce the eLD-efLD difference using Machine Learning (ML).
