Introduction and Objectives: To compare the efficacy and outcomes of two types of shock wave machines,the electrohydraulic lithotriptor (E3000) and electromagnetic lithotriptor (EM 1000), as treatment of upper urinary tract stones.Methods: The efficacy and outcomes of shock wave lithotripsy (SWL) using Medispecs E3000 electrohydraulic shock wave lithotriptor (179 cases) and Medispecs EM1000 electromagnetic shock wave lithotriptor (93 cases) in 272 patients with upper urinary tract stones Results and Limitations: re-SWL, the patient characteristics, treatment parameters, and stone-related parameter were similar for both groups.Theelectrohydraulic group had higher stone-free rate for renal and upper third ureter stones compared with EM group (53.6％ vs.30.1％, p＜0.001).Theelectromagnetic group had higher retreatment rate (32.4％ vs.61.2％,p＜0.001) for renal and upper third ureter stone.There was no significant difference for stones at the middle and lower ureter and stones in the ureter bigger than 1 cm.The complication rates for pain, skin, or subcapsular hematoma were not significantly different between groups.Conclusions: The electrohydraulic lithotriptor (Medispec E3000) group has significantly higher disintegration and stone-free rates, but has similar complication rates compared to the electromagnetic lithotriptor (Medispec EM 1000) group.There is no significant difference between the two groups for middle or lower ureteral stones and ureteral stones bigger than 1 cm.The electromagnetic lithotripter has the advantage of being useful for SWL even without anesthesia.
