Disclosed herein is a stone removing apparatus and a stone size measuring method, which can take a picture of a stone and measure the size of the stone in order to stably remove the stone without damaging a human body. The stone removing apparatus includes: an insertion tube having an inner space; a guide tube inserted into the inner space of the insertion tube to be moved; a wire inserted into the guide tube to be movable; a basket disposed at the front of the wire to grasp a stone; an imaging unit disposed at the front end of the guide tube in order to take an image of a stone grasped by the basket; and a control unit electrically connected with the imaging part to analyze the image taken by the imaging unit, wherein the control unit calculates a distance between the imaging unit and the basket to measure the actual size of the stone using the calculated distance.
