Of 355 patients undergoing nonoperative extraction procedures for retained bile duct stones, 61 patients had intrahepatic calculi. In seven of these patients with multiple intrahepatic stones and two of them with additional hepatic duct strictures.trahepatic stones, a U tube was placed. Insertion of a U tube is particularly useful if multiple sittings are required for intrahepatic stone removal. The U tube can be inserted postoperatively and permits ease of operation from two sides, particulary if stricture dilation is required before stone removal. With the use of the U tube, inadvertent removal has not occurred and patients are able to work and shower between extraction procedures. Indwelling U tubes are readily replaced over a guide wire. This technique was used with good success and for long periods of time in seven patients, all with multiple intrahepatic stones and two of them with additional hepatic duct strictures.
在355例行胆管残余结石非手术取石术的患者中，61例有肝内结石。在这些有多个肝内结石的患者中，有7例以及另外2例合并肝管狭窄的患者放置了U形管。如果需要多次进行肝内结石清除术，插入U形管特别有用。U形管可在术后插入，便于从两侧进行操作，尤其是在取石前需要扩张狭窄部位时。使用U形管后，未发生意外拔除情况，患者在取石过程之间能够工作和淋浴。留置的U形管可通过导丝轻松更换。该技术在7例患者中取得了良好且长期的效果，所有患者均有多个肝内结石，其中2例还合并肝管狭窄。
