[Shock wave lithotripsy for ureteral stones--single institute experience in 661 consecutive cases].

Introduction: Optimal treatment for ureteral stones is still controversial. The main retreatment options include ureteroscopy and shock wave lithotripsy (ESWL). The study aimed to assess the efficacy of ESWL using the unmodified HM3 lithotripter (Dornier Medical Systems) to achieve stone-free status in patients with ureteral calculi, regardless of stone size and location along the ureter.
