摘要目的 探讨局麻下经皮肾镜取石术(PCNL)的可行性及安全性.方法 局麻B超引导下行PCNL 1363例,其中复杂性肾结石475例,肾盂结石520例,输尿管上段结石368例.采用1%～2%盐酸利多卡因10～20 ml自穿刺点皮肤开始沿穿刺方向行浸润麻醉,深达肾筋膜区域.术中采用"0～10"疼痛强度量表评估疼痛程度.结果 1363例均一次穿刺成功并行一期PCNL,其中5通道2例,4通道4例,3通道9例,2通道25例,单通道碎石1323例.肾盂结石取净500例(96.2%),输尿管上段结石均取净(100.0%),复杂性肾结石取净428例(90.1%).疼痛评分0～3分者818例(60.0%),4～6分者409例(30.0%),7～9分者136例(10.0%).10%疼痛评分≥7分者局部予1%～2%盐酸利多卡因5～10 ml或盐酸哌替啶50～75 mg肌肉注射后缓解,无一例因疼痛难以忍受而变动体位或停止手术者,术中未发生肝、脾、胸腔、肠管损伤等严重并发症.结论 局麻B超引导下行PCNL术简单安全有效,值得临床推广运用.

abstractsObjective To discuss the feasibility of percutaneous nephrolithotomy (PCNL) for treating upper urinary calculi under local anesthesia.Methods One thousand three hundred and sixty-three patients who suffered with upper urinary calculi were treated with PCNL, the puncture and tracts were created using local anesthesia and guided through ultrasound.Of the 1363 patients, 475 patients had complicated renal caluli, 520 patients had kidney pelvic calculi and 368 had upper uretere calculi.Results All of the patients successfully received PCNL under the local anesthesia.Of the 1363 patients five tracts were used in two patients, four tracts were used in four patients, three tracts were used in nine patients, double tracts were used in 25 patents and one tract was used in the remaining patients.The stone-free rate was 96.0% in the kidney pelvic calculi patients, 100.0% in the upper uretere calculi patients, and 90.1% in the complicated renal caluli patients.90.0% patients were find well throught the operation, 10.0% patients find a little pain and solved by another more 5 - 10 ml lidocaine local injection or 50 - 75 mg pethidine hydrochloride intramuscular injection.No case stop operation because of pain or position changed.All without any severe complications such as damaged of liver, spleen, thorax and intestine.Conclusion The PCNL handled under local anesthesia was simple safe and effective, deserved clinical popularizing use.
