【摘要】 目的分析低压冲洗在微创经皮肾碎石术中的应用效果。方法 40例输尿管上段结石及肾结石患者在硬膜外阻滞下采用腔内气压弹道碎石器在输尿管镜直视下碎石,术中通过液体灌注泵持续冲洗,如术野显露不清晰时,加用三通,用50ml注射器加压短时间冲洗。观察术后效果。结果 40例患者中单次碎石取石成功26例,二次碎石取净结石7例,部分结石残留5例,大部分结石残留2例。手术时间1～2.5h,住院时间5～15(7.5±0.5)d。术后均未出现出血及感染扩散情况。结论采用腔内气压弹道碎石器在输尿管镜直视下碎石,术中联合液体灌注泵和三通低压冲洗,取得较满意效果,值得临床推广应用。更多还原

【Abstract】 Objective To analysis the effect of low-pressure flushing on the minimally invasive percutaneous renal lithotripsy.Methods Under the condition of epidural block,40 cases patients with upper ureteral stone and kidney stone were treated by cavity pneumatic lithotripsy via ureteroscope.Continued irrigation by liquid infusion pump in the intraoperative.If the operative field was unclear,you can plus the three-way and press irrigation by 50ml syringe in a short time.Results There were 26 cases patients were successfully cured in the first time,7 cases were cured in the second time.There were 5 cases patients were still remained part of calculi,2 cases were remained large of calculi untill now.The operative time arranged from 1~2.5h,hospitalization time arranged from 5~15(7.5±0.5)d.There were not patients with bleeding and infection.Conclusion The applied of low-pressure flushing in the minimally invasive percutaneous nephrolithotomy lithotripsy achieved the more satisfactory effect,it is worthy of further clinical promotion and application.更多还原
