Pneumatic ballistic lithotripsy via outer sheath of resectoscope in the treatment of bladder calculi: Report of 20 cases / 中国微创外科杂志

ABSTRACT

Objective To investigate a new method of pneumatic ballistic lithotripsy for the treatment of bladder calculi. Methods A ureteroscope or nephroscope was inserted into the bladder via outer sheath of resectoscope. Then pneumatic ballistic lithotripsy was performed under endoscope to fragment and remove bladder stones. Results Stones were thoroughly removed from the bladder on one session in all 20 patients. No major haemorrhage, perforation of the bladder, or water intoxication happened intraoperatively or postoperatively. Follow-up for 2~18 months (mean, 4 6 months) in the 20 patients showed no recurrence of calculi under B-ultrasonography or symptoms of urethral stricture like dribble urination. Conclusions Pneumatic ballistic lithotripsy via outer sheath of resectoscope is effective in the treatment of bladder calculi.
