Abstract

Introduction: The aim of the study was to observe the success rate of extracorporeal shock wave lithotripsy (ESWL) in the management of upper urinary tract stones.

Materials and Methods: This retroprospective study was conducted in Pokhara Kidney stone Centre, Pokhara, Kaski, Nepal from January 2017 to January 2018. Seventy nine patients were selected in this study with upper urinary tract stone, size less than 20 mm.

Results: Seventy four (93.67%) patients were successfully treated in initial use of shock wave and 5 (6.32%) patients required repetition.
