Factors That Affecting Success and Re-admission in the Treatment of Proximal Ureteral Stones with Shock Wave Lithotripsy

Abstract

Introduction: Extracorporeal shock wave lithotripsy (ESWL) is one of the methods applied in urinary system stone disease. ESWL has a very high success rate, and there are many factors that affect its success. In our study, we aimed to present our shock wave lithotripsy (SWL) results in proximal ureter stones, the reasons for re-admission to the hospital after SWL, and the final success achieved after additional interventions. Methods: Between March 2017 and October 2019, 142 patients aged 18 years and over who underwent SWL for proximal ureteral stones were retrospectively evaluated. Age, sex, body mass index, stone laterality, stone size and volume (π×1/ 6×length×width×height), stone-skin distance, stone density, hydronephrosis degrees, number of SWL sessions, reasons for re-admission, and final success results were evaluated. The stone size determined on CT0.05). Factors affecting ESWL success include male gender, stone size, stone volume, and stone density; stone-skin distance and degree of renal ectasia were found to affect final success (p
