Preoperative Nomograms for Predicting Stone-Free Rate After Extracorporeal Shock Wave Lithotripsy

This study demonstrated that stone size, location and number are significant predictors of extracorporeal shock wave lithotripsy outcome. We have developed nomograms for predicting the stone-free rate of extracorporeal shock wave lithotripsy, which is useful for counseling patients with urolithiasis before surgery.
