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).
Conclusion: ESWL is an effective treatment modality in emergency for small-length and short-term obstruction bilateral ureteral stones with remal colic.
