目的探讨输尿管镜下超声弹道碎石术治疗急性梗阻性肾衰竭的疗效。方法由输尿管结石引起的急性肾后性梗阻22例,均在急诊行输尿管镜下运用EMS三代碎石清石设备进行治疗。结果均成功实行输尿管镜手术,一次性碎石成功率81.8%,肾功能均有不同程度改善,未出现肾功能恶化、严重感染、输尿管撕脱等并发症。结论输尿管镜下超声弹道碎石术处理急性梗阻性肾衰竭,能迅速解除梗阻恢复肾功能,并能同时处理双侧病变,是一种安全、有效、微创的治疗方法。
Objective To investigate the efficacy of ureteroscopic ultrasound lithotripsy in the treatment of acute obstructive renal failure. Methods Twenty-two cases of acute renal obstruction caused by ureteral calculi were treated by emergency ureteroscopy with three-stage lithotripsy by EMS. The results were successfully implemented ureteroscopic surgery, a one-time success rate of 81.8% gravel, renal function improved in varying degrees, no deterioration of renal function, severe infection, ureteral avulsion and other complications. Conclusions Ureteroscopic ultrasound-guided lithotripsy is a safe, effective and minimally invasive treatment for acute obstructive renal failure, which can quickly relieve obstruction and restore renal function, and can treat bilateral lesion at the same time.
