经电切镜外鞘气压弹道治疗膀胱结石20例报告

Pneumatic ballistic lithotripsy via outer sheath of resectoscope in the treatment of bladder calculi: Report of 20 cases

目的探讨气压弹道治疗膀胱结石的新方法. 方法经电切镜外鞘置入输尿管镜或肾镜,气压弹道将膀胱结石击碎取出. 结果 20例均顺利一次性将结石取尽.术中、术后无大出血、膀胱穿孔和水中毒等并发症.20例术后随访2～18个月,平均4.6月,B超未见结石复发,无排尿不畅等尿道狭窄症状. 结论电切镜外鞘气压弹道碎石是处理膀胱结石的有效方法.

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.
