Clinic application of pneumatic lithotripsy under ureteroscope in the treatment of 300 cases of ureteric stones

Objective: To evaluate of clinical effect for the ureteric stones by pneumatic lithotripsy under ureteroscope for ureteral calculi.Methods: 300 cases of ureteral calculus underwent pneumatic lithotripsy under ureteroscope for gravel and stone therapy.Results: Out of 300 cases of patients,46 failed with a ratio of 15.33%.After operation,we were compared the two groups and found upper ureteral calculi lithotripsy had a higher failure rate and a longer average operation time than that of middle and lower ureteral stones,differences were statistically significant(P0.01).Conclusion: Treatment of ureteral ureteric with pneumatic lithotripsy under ureteroscope is less invasive,safe,effective,but not ideal for upper ureteral calculi.
