title: Ureterolithotripsy in the management of calcified double-J catheter.
abstract: OBJECTIVE
  The authors present their experience in the management of a rare complication observed during long-term use of a ureteral catheter. The calcification along the entire surface of the catheter followed by incrustation can make its removal by means of cystoscopy difficult, thus becoming a great challenge to the urologist.
  
  
  METHODS
  The authors describe their experience in the management of this complication through the analysis of two illustrative cases.
  
  
  RESULTS
  After failing to remove the catheter using extracorporeal lithotripsy, ureterolithotripsy was performed and the calcified ureteral catheter was successfully removed in both cases.
  
  
  CONCLUSIONS
  Ureterolithotripsy proved to be an effective and safe method in the management of calcified double-J catheter.
