title: [Extracorpreal shockwave lithotripsy in treatment of bilateral ureteral calculi with renal colic during emergency].
abstract: OBJECTIVE
  To evaluate the clinical efficacy of extracorporeal shockwave lithotripsy (ESWL) for bilateral ureteral stones with renal colic in emergency.
  
  
  METHODS
  We retrospectively analyzed the clinical data of 86 patients suffered with sudden renal colic due to bilateral ureteral stones and treated with ESWL between January 2005 and January 2009.
  
  
  RESULTS
  The success rate was 74.4% after a single ESWL session, and the overall success rate was 82.6%. Significant difference in stone length was observed between successful group and failed group (P<0.01). The stone position did not produce significant impact on the outcome of the treatment (P>0.05).
  
  
  CONCLUSIONS
  ESWL is an effective treatment modality in emergency for small-length and short-term obstruction bilateral ureteral stones with remal colic.
