Objective To evaluate the efficicy and safety of extracorporeal shock wave lithotripsy(ESWL) in the treatment of urinary calculi in children.Methods 47cases of paediatric urinary calculi treated with ESWL from 2006 to 2010 were analysed retrospectively and discussed with review of the literature.Of the 47 children,19 had nephrolith,22 had ureter calcli,4 had bladder and 2 had posteriorurethra calculi.Results The overall stone free rate after ESWL was 95.6%,and the successful rate was 97.8%.Two cases(4.2% ) have residual fragments.Only one case(2.1% ) was failure then treated with open surgery.Stone was quickly and smoothly relased with little complications.Conclusion ESWL is a safe and effective treatment for paediatric urolithiasis,so it should be considered the first choice to treat paediatric urinary calculi.
