An atraumatic double-ballooned catheter was designed to extract endoscopically ureteral calculi of relatively large size (1 to 1.5 cm.) arrested at any level of the ureter. This reduces the need for ureterolithotomy, eliminates the problems of stone basket manipulations, and reduces the need for prolonged waiting for spontaneous migration of stones.
一种无创双气囊导管被设计用于通过内镜取出停留在输尿管任何部位的相对较大尺寸（1至1.5厘米）的输尿管结石。这减少了输尿管切开取石术的需求，消除了结石篮操作的问题，并减少了长时间等待结石自然排出的必要性。
