In a preliminary communication a new method for endoluminal extraction of ureteral stones is described by using a catheter with two inflatable balloons. The length of the catheter is about 100 cm and its diameter corresponds to the usual ureteral catheters. It has four openings: the central opening is located at the end of the catheters. Two other lumina open into the two balloons located at a distance of 3-5 cm. An other opening is located between the two balloons. By insufflating and emptying of the distal balloon, the concrement in the ureter is mobilized and caught. By insufflating the two balloons and injection of contrast media through the opening situated between the two balloons, the ureter is ovistended, the stone is mobilized can be extrac "swimming" ie contrast media between the two balloons. Tillenow, o concrements have been extracted from the distal ureter by this method.
在一篇初步通讯中，描述了一种使用带有两个可充气气囊的导管进行输尿管结石腔内取出的新方法。导管长度约100厘米，其直径与常用的输尿管导管相当。它有四个开口：中央开口位于导管末端。另外两个管腔通向位于3 - 5厘米远处的两个气囊。另一个开口位于两个气囊之间。通过向远端气囊充气和放气，可移动并捕获输尿管内的结石。通过向两个气囊充气并通过位于两个气囊之间的开口注入造影剂，可使输尿管过度扩张，结石可被移动并可通过两个气囊之间的造影剂“游动”而取出。到目前为止，已通过这种方法从远端输尿管取出了结石。
