title: Pneumatic lithotripsy for ureterolithiasis: clinical analysis of 512 cases.
abstract: OBJECTIVE
  To investigate the therapeutic effects of pneumatic lithotripsy (PL) through ureteroscope in the treatment of ureterolithiasis.
  
  
  METHODS
  The clinical application of rigid ureteroscopy in 512 cases were retrospectively analyzed.
  
  
  RESULTS
  Among the 512 cases, 486 had satisfactory therapeutic effects with the success rate of 94.9%. Failure of ureteroscope insertion occurred in 12 cases, leaving a success rate for the insertion of 97.7% (500/512). During the operations, ureteral stones in 14 cases failed to be eliminated, and the total success rate of PL reached 97.2% (486/500).
  
  
  CONCLUSIONS
  The therapeutic effects of PL through ureteroscope were reliable and safe in the treatment of ureteral stones, with rapid postoperative recovery.
