Percutaneous renal and ureteral stone removal procedures are widely practiced. A new technique is described for removal of small symptomatic ureteral calculi using small (less than or equal to 14 French) tearable sheaths and standard stone retrieval baskets placed through acute percutaneous nephrostomy tracks. This fluoroscopically-guided technique was successful in 60 of 64 patients, who ranged from 16 to 88 years old. Subsequent endoscopic percutaneous calculus removal was successful in the four failures. The use of these small sheaths over previously described large tracks has produced no major complications, short hospital stays, and minimal patient disability.
经皮肾和输尿管结石清除手术应用广泛。本文描述了一种新技术，使用小口径（小于或等于14法式）可撕开鞘管和标准结石取出篮，通过急性经皮肾造瘘通道取出有症状的小输尿管结石。这项在荧光镜引导下的技术在64例年龄在16至88岁的患者中，60例取得成功。其余4例失败患者随后经内镜经皮结石清除术成功。与之前描述的大通道相比，使用这些小鞘管未产生重大并发症，住院时间短，患者残疾程度低。
