目的:探讨仰卧位经臀部体外冲击波碎石治疗输尿管下段结石的效果。方法:2010年10月~2012年9月收治636例输尿管下段结石患者,接受仰卧位经臀部体外冲击波碎石治疗。结果:输尿管下段结石碎石率达100%;一次ESWL结石排尽率593例(93.2%);二次ESWL结石排尽率40例(6.3%),总排石率99.5%;二次ESWL后有结石残留3例(0.5%),进一步检查明确诊断并改其他手术治疗。无一例发生神经损伤。结论:仰卧位经臀部体外冲击波碎石治疗输尿管下段结石安全、有效,可避免肠道损伤,应是输尿管下段结石的首选体位。
Objective: To investigate the effect of supine hip extracorporeal shock wave lithotripsy on the lower ureteral calculi. Methods: From October 2010 to September 2012, 636 patients with lower ureteral calculi underwent supine position with hip extracorporeal shock wave lithotripsy. Results: The rate of lithotripsy of the lower ureter reached 100%. The number of primary ESWL stones was 593 (93.2%), the rate of secondary ESWL stones was 40% (6.3%), the total rate of stone discharge was 99.5%. After ESWL There are 3 cases of residual stones (0.5%), further examination to confirm the diagnosis and change to other surgical treatment. No case of nerve injury occurred. Conclusion: The supine position by the buttocks extracorporeal shock wave lithotripsy in the treatment of lower ureteral calculi is safe and effective, to avoid intestinal damage should be the preferred position of lower ureteral calculi.
