ESWL Outcome Prediction with SMOTE and Stratified Sampling

In recent years, extracorporeal shock wave lithotripsy (ESWL) and transurethral lithotripsy (TUL) have become the primary treatments for ureteral stones. ESWL is less physically burdensome than TUL and requires a shorter treatment period, but its success rate is lower compared to TUL. Therefore, selecting the appropriate treatment method in clinical practice is essential. This study aims to reduce the physical and financial burden on patients by predicting the outcomes of ESWL, thereby minimizing the need for dual treatments. In this study, stratified sampling was performed on the features examined in previous studies and combined with oversampling by SMOTE to assess the impact on the prediction accuracy of ESWL outcomes. As a result, we confirmed that stratified sampling and SMOTE improved prediction accuracy.
