title: [Comparative study of pneumatic lithotripsy and holmium laser lithotripsy for ureteral stones].
abstract: OBJECTIVE
  To compare the efficacy and safety of endoscopic laser lithotripsy (LL) and endoscopic pneumatic lithotripsy (PL) for ureteral stones.
  
  
  METHODS
  We retrospectively analyzed the clinical data of 415 patients with ureteral calculi treated with endoscopic laser lithotripsy (n = 214 ) and pnumatic lithotripsy (n = 201 ).
  
  
  RESULTS
  The overall successful fragmentation rate of all ureteral stones in a single session of the LL group was higher than that of the PL group (95% vs. 69%, P < 0.01). The average stonefree time of the LL group was shorter than that of the PL group (18 days vs. 31 days, P < 0.01). No complications such as perforation during the operation were observed in the LL group whereas 3 perforations occurred in the PL group.
  
  
  CONCLUSIONS
  LL has its advantage over PL in its better clinical effect for the stone fragmentation and low complication rate and is an effective and safe treatment for ureteral stones.
