ABSTRACT:
An ureteral stent comprises an elongated, flexible tubular member which has proximal and distal ends in the form of hooks. Both of the ends of the member are open but the opening at the proximal end is smaller than the lumen or the opening at the distal end. Methods of inserting the stent, maneuvering the stent past difficult obstructions in the ureter, replacing an indwelling stent are described, as well as kits for performing those methods.
