侧卧位经皮肾微造瘘输尿管镜取石对老年上尿路结石患者治疗安全性的研究

目的探讨经皮肾镜治疗老年患者上尿路结石的安全性。方法回顾性分析我院采用侧卧位经皮肾微造瘘输尿管镜取石治疗老年上尿路结石19例患者的临床资料。结果16例一期手术取石成功，3例二期取石。一期手术结石取净率为84％（16／19）。术中和术后无输血。术后肺部感染1例，抗感染治疗3dB体温正常，无其他明显并发症。术后随访平均14个月。B超检查提示肾积水均较术前明显改善，未见结石复发。结论在充分的术前准备，合理的麻醉及术中严密观察及熟练手术操作下，经皮肾镜碎石是治疗老年人复杂上尿路结石的安全有效措施。

Research to the safety in treatment of the elderly patients of upper urinary tract calculi with minimally invasive percutaneous nephrolithotomy in lateral decubitus position

Objective To study the safety of percutaneous nephroscope nephrolithotripsy in treatment of the elderly patients of upper urinary tract calculi. Methods To analyse the 19 cases which had been given the treatment to the elderly patients of upper ufinary tract calculi through pereutaneous micronephrostorny and ureteroscopy under side - lying position. Results Sixteen cases achieved stone free at primary, procedure,secondary procedure was needed in 3 eases. Stone -free rate was 84% （16/19）. There was no blood transfusion. One patient had puhnonary infection after the procedure and recovered 3 days after the administration of antibiotics. No other complication was recorded. In an average 14 month follow -up in 19 patients ,hydronephrosis reduction was significant observed by ultrasound scan. No calculus relapse was found. Conclusions Percutaneous nephroscope nephrolithotripsy in treatment of the elderly patients of upper urinary tract calculi is the safe and effective measures to sufficient preoperative preparation ,reasonable anesthetic method ,intensive observation intraoperation and proficiency of skills.
