摘要：
A method for removing a kidney stone from a ureter may involve: advancing a distal end of an elongate, flexible kidney stone removal device into the ureter to a location near the kidney stone； advancing an expandable stone retention member out of an inner shaft of the device； visualizing at least part of the stone retention member with a camera disposed coaxially within the stone retention member； trapping the kidney stone in the stone retention member； surrounding at least a portion of the stone retention member and the trapped kidney stone with a wall protection member on the distal end of the kidney stone removal device； and removing the kidney stone removal device from the ureter while the stone retention member and the kidney stone are at least partially surrounded by the wall protection member.
