Abstract：Objective To investigate the influencing factors of ureteroscopic pneumatic ballistic lithotripsy (URSL) in the treatment of complicated ureteral calculi.Methods From June 2009 to July 2013, clinical data of 132 cases with complicated ureteral calculi at Tongling People′s Hospital were retrospectively analyzed. Among them, the successful operation for 111 cases as group A and 21 failed cases as group B , test was used to investigate the effect of treatment and influencing factors of patients in two groups.Results When the course of disease was more than 8 weeks, incarceration stones, stone size had significant difference (all P values<0.05), which were dangerous influencing factors of URSL in the treatment of complicated ureteral calculi.Conlusions According to the factors of URSL effect, when the course of of disease is more than 8 weeks, incarceration and larger stones, effective measures should be taken to reduce the proportion of ureteroscopic lithotripsy failure.
