title: [Effect of extracorporeal shock-wave lithotripsy on residual stones after different methods of surgery].
abstract: OBJECTIVE
  To observe the effect of extracorporeal shock wave lithotripsy (ESWL) on residual stones after different methods of surgery.
  
  
  METHODS
  Clinical resources of 100 patients with residual stones after different methods of surgery treated with extracorporeal shock wave lithotripsy from May 2006 to May 2008 were retrospectively studied. Of the 100 patients, ureteroscopic laser lithotripsy was used for 15 patients (Group I), ureteroscopic pneumatic lithotripsy was used for 25 (Group II), mini-percutaneous nephrolithotomy (MPCNL) with holmium laser for 11 (Group III), mini-percutaneous nephrolithotomy (MPCNL) with air pressure path lithotripter for 12 (Group IV), open surgery for the other 37 (Group V).
  
  
  RESULTS
  About 94% of the residual stones were shattered, and 86% of the residual stones were cleared successfully. The clearance rate of residual stones from Group Ito V was 100%, 100%, 81.8%, 83.3%, and 73.0%, respectively. The clearance rate of residual stones in Group I+II was higher than that of Group III+IV and Group V(P<0.05).
  
  
  CONCLUSIONS
  Extracorporeal shock wave lithotripsy is good for the treatment of residual stones after different methods of surgery, especially the management of residual stones after trans-urethral ureteroscope technique.
