Ureteroscopic Pneumatic Lithotripsy for Residua Ureteral Calculi after Extracorporeal Shockwave Lithotripsy

Objectiv to evaluate clinical efficacy of ureteroscopic pneumatic lithotripsy for residua ureteral calculi after ESWL.Methods 85 patients with ureteral calcui that treated with uretterosopic pneumatic lithotripsy after unsuccessful ESWL were analyzed.Results 79 of 82 patients with ureteral calculi were succeeded pneumatic ureteroscopic lithotripsy at the one time.3 patients with big stone returned to kidney were given ESWL for second time.The calculi in all patients were discharged thoroughly after two month.Only one case was treated with operation because naarrowed ureter was difficult for ureterospoce to reach the stone.The other two patients was treated with operation because the perforation was occured during the application of ureteroscope because of resulting from the narrow below calculus.Conclusion Ureteroscopic pneumatic lithotripsy is a safe and effective treatment for residua ureteral calculi after ESWL.It should be considered as the first choice of treatment.
