title: Ureteric stone extraction by a new double-balloon catheter: an experimental study.
abstract: 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.
