Objectives: To compare the efficacy of the Dornier Compact Delta lithotriptor with the Northgate SD-3 lithotriptor in the treatment of upper and mid-ureteral stones. Materials and Methods: A total of 243 patients without any previous experience of ESWL were treated for upper and mid-ureteral stones. 121 patients were managed with the Northgate SD-3 lithotriptor which had ultrasonography targeting system and electro hydraulic shock wave source. The other 122 patients were treated with the Dornier Compact Delta equipped with a fluoroscopic focusing system and electromagnetic shock wave source. The locations and sizes of stones, sessions, stone-free rates, auxiliary procedures, and complications of ESWL were reviewed retrospectively. In each group stone-free results were determined by KUB 1 month after the last ESWL and then efficacy quotients (EQ) were obtained. Results: Baseline characteristics were equivalent, including patient ages, sex ratio, stone numbers and locations. Using the Northgate SD-3 lithotriptor, the average sessions and stone-free rates were 1.53 and 86.8%, respectively. Using the Dornier Compact Delta lithotriptor, average sessions and stone-free rate were 1.38 and 92.6 %, respectively. Effectiveness quotient(EQ) in the Northgate SD-3 and the Dornier Compact Delta was 61 and 65, the rates of the auxiliary procedure were 9.1% and 18%. Conclusions: The Dornier Compact Delta lithotripsy resulted in a higher stone-free rate and EQ, although it was associated with a higher rate of pre-ESWL auxiliary procedures than the Northgate SD-3 Lithotripsy.
