Comparison of Guy and Clinical Research Office of the Endourological Society Nephrolithometry Scoring Systems for Predicting Stone-Free Status and Complication Rates After Percutaneous Nephrolithotomy: A Single Center Study with 437 Cases

Abstract

Both GSS and CROES nomograms had comparable accuracies in predicting post-PCNL stone-free status. Different from the previous reports, our results showed that both nomograms were predictive of overall complications, EBL, and operative time.
