Predictors of Auxiliary Procedures After Extracorporeal Shock Wave Lithotripsy: A Retrospective Study
Abstract: Background: Extracorporeal Shock Wave Lithotripsy (ESWL) is widely used for urolithiasis; however, a subset of patients require auxiliary procedures for definitive clearance. Identifying predictors can aid in optimal patient selection. Aim: To evaluate factors predicting the need for auxiliary procedures following ESWL. Materials and Methods: A retrospective study was conducted from April 2025 to March 2026 including 100 patients undergoing ESWL for renal or ureteric calculi. Variables analyzed included age, gender, stone size, location, density (HU), and skin-to-stone distance (SSD). Auxiliary procedure was defined as need for ureteroscopy (URS) or percutaneous nephrolithotomy (PCNL) following failed ESWL. Results: Out of 100 patients, 20 required auxiliary procedures (20%). Larger stone size (>12 mm), higher density (>1000 HU), lower pole location, and SSD >10 cm were significantly associated with auxiliary intervention (p<0.05). On multivariate analysis, stone size and HU remained independent predictors. Conclusion: Stone size and density are strong predictors of ESWL failure requiring auxiliary procedures. Careful patient selection can reduce the need for secondary interventions.
