Report of Pneumatic Lithortripsy under Ureteroscope for 453 Cases of Ureteral Calculi

Objective To summarize and compare the clinical effects and experience of pneumatic lithotripsy under ureteroscope for ureteral calculi.Methods Retrospectively the data of 453 cases of ureteral calculi were analysed.Results The whole success rate is 92.7%(The success rates for upper,middle and lower ureteral calculi were 76.0%,93.0% and 96.0% respectively)and the complication rate is 8.4%.Conclusion Ureteroscope could be put into most ureter with the method of stiring up-turning medially under automated irrigation/suction pump system.Pneumatic lithotripsy under ureteroscope is an effective method and should be the first choice of treatment for middle and lower ureteral stones.For most failed patients,extracorporeal shock wave lithotripsy(ESWL)should be undergone after inserting D-J catheter and maybe succeed at last.
