1. Objective To evaluate the availability of ballistic lithoclast in treatment of ureteral calculi.

2. Objective To evaluate the value of swiss lithoclast under ureteroscop in the treatment of 83 cases of middle and lower ureteral stones.

3. Methods Choledochfiberscope(CHF) combined with air pressure ballistic lithoclast(APBL) under ureterscopy were used on 28 cases of large or impacted residual gallstones.

4. Conclusion: The ballistic lithoclast , as a new technique, is claimed to be safe and a high success rate and less trauma, which is valuable to be greatly spread.

4. try its best to collect and create good sentences.

5. Objective: To evaluate the treatment of posterior renal failure caused by ureteric with ureteroscopy and Swiss lithoclast pneumatic lithotripter.

6. Methods Clinic and follow-up results were reviewed in 20 patients with refractory bile duct stones who were treated by Swiss LITHOCLAST with chola ngioscopy.

7. Conclusion Treatment of posterior renal failure caused by ureteric calculi with ureteroscopy and Swiss lithoclast pneumatic lithotriptor is safe, effective and less invasive.

8. Methods:Thirty patients of complicated renal calculi were managed by mini-PCNL under ureteroscopy and Swiss lithoclast .

9. Objective To evaluate the clinical efficacy of percutaneous nephrolithotomy using third generation Swiss LithoClast Master under ultrasound guidance in treating upper urinary tract calculi.

10. Objective:To evaluate the perioperative nursing of upper urinary tract calculi treated with percutaneous nephrolithotomy using third generation Swiss Lithoclast Master under ultrasound guidance.

11. Methods Between December 1998 and December 2001,186 patient with stone in the ureter were treated with Swiss lithoclast pneumatic lithotriptor in the ureteroscope management.

12. Objective To evaluate the clinical effect of ureteroscopic ballistic lithoclast in the treatment of ureteral calculi.

13. In the Q-F-L graph, the plotted points of quartz, feldspar and lithoclast contents of Cretaceous sandstone-mudstone cored from wells are mainly located in foreland basin area.

14. Objective: To evaluate clinical use of double J tube as an endo-sent in the Swiss lithoclast pneumatic lithotriptor in the endoscopic management of urinary calculi.

15. Objective To evaluate the treatment of posterior renal failure caused by ureteric calculi with ureteroscopy and Swiss lithoclast pneumatic lithotriptor.
