Abstract

Introduction: Preoperative assessment of renal stones is essential to selecting treatment options and achieving high success rates; thus, some nephrolithometric scoring systems have been developed by using preoperative clinical data and stone characteristics. Initially, nomograms predicting stone-free rates (SFRs) were designed for percutaneous nephrolithotomy. After this, some were modified, and new scoring systems were developed for retrograde intrarenal surgery (RIRS). In this study, we aimed at validating and comparing the accuracy of four scoring systems predicting the SFR of RIRS.
