Background & Aim: The available treatment for renal and upper ureteral stones less than 20-25 millimeters is extracorporeal shock wave lithotripsy (ESWL). The aim of this study was to evaluate the efficacy of Arian 101 Lithotriptor in treatment of renal and upper ureteral stones. Methods: In this clinical trial which was conducted from 2007 to 2008 at Yasouj University of Medical Sciences, 184 patients older than 18 years of age with renal and upper ureteral stones between 6-20 millimeter who were candidate for ESWL enrolled the study, after taking informed consent. ESWL was in progress in supine position with guide of fluoroscopy by Arian 101 Lithotriptor, using standard technique. The power of Lithotriptor began from 12 KV and increased to 18 kilovoltages during 10 minutes. Patients which need more than 5000 shock were considered as unresponsive. Two weeks later, patients visited again and followed by KUB and ultrasonography and success of ESWL was recorded according to changing in stone size and residual stones. Lithotripsy was repeated in patients with residual stones larger than 5 millimeters. All collected data were analyzed using the Chi-square test. Results: Efficacy of Arian 101 Lithotriptor in removing of renal stones larger than 10 millimeter were found to be as 42.8% complete response, 29.7% partial response while 27.4% of subjects had no response. Its efficacy in upper ureteral stones larger than 10 millimeter were as 40% complete response, 26% partial response and 34% had no response. The complete responses in renal and upper ureteral stones smaller than 10 millimeter were 54.9% and 46.7% respectively. Conclusion: This study showed that Arian 101 Lithotriptor has suitable efficacy in treatment of stones less than 10 millimeter, but its efficacy in removing of stones larger than 10 millimeter is not satisfactory. Further studies is needed to verify these findings.
