Comparison of different shock wave frequencies on stone disintegration in extracorporeal shock wave lithotripsy; 60, 80 and 100/min

Abstract Background We know that SWL started on February 07, 1980, by Christian Chaussy with a wide range of indications. Complication rate has always remained very low and usually limited to minor side effects complications. This study shows the impact different shock wave release frequencies 60, 80 & 100/min disintegration renal stones. Methods A total number 210 patients mean age (40 ± 15) years stone who were candidate for divided into 3 groups each are 70 60,80 100 per min), Chi-Square test, Fisher’s exact test used in study. Results Complete clearance( defined as complete free) was obtained 184 87.6% after one session, highest success 94.3% second group ( frequency 80/min) followed first 87.1% (with 60/min), (100/min) had lowest 81.4%. Conclusions The best option is using intermediate 80/min obtain mild pain. Using high not favorable due least 60/min less than despite it painful.
