Comparison of Scoring Systems in Predicting Success of Percutaneous Nephrolithotomy

Background: Scoring systems are useful to inform the patients about the success and complication rates of the operation prior the surgery.Aims: To determine the applicability of the popular scoring systems (Guy’s, stone size, tract length, obstruction, number of involved calices, and essence/stone density and Clinical Research Office of the Endourological Society) by means of examining preoperative data of patients treated with percutaneous nephrolithotomy.Study Design: Cross sectional study.Methods: We retrospectively reviewed files of the patients who had undergone percutaneous nephrolithotomy in our center between 2011 and 2015. Excluded from the study were patients aged
