متن کاملExternal Validation and Evaluation of Reliability and Validity of the S-ReSC Scoring System to Predict Stone-Free Status after Percutaneous Nephrolithotomy
OBJECTIVES The Seoul National University Renal Stone Complexity (S-ReSC) scoring system was developed to predict the stone-free rate (SFR) after single-tract percutaneous nephrolithotomy (PCNL). This study is an external validation of this scoring system. MATERIALS AND METHODS A retrospective review included 327 patients who underwent PCNL at 2 tertiary referral centers. The S-ReSC score was ...
