The invention relates to a stent provided with cauterization system. A stent operating apparatus in which a stent moves to a lesion of a tubular tissue through a plurality of pipe members and performs an operation includes: a bipolar electrode for cauterization configured to be disposed at an operation end of the pipe member to cauterize the lesion and a high frequency generator configured to be connected to the bipolar electrode for cauterization to allow the bipolar electrode for cauterization radiate a high frequency current, whereby the lesion may be cauterized and necrotized by the bipolar electrode of a tip portion of a moving pipe charged with the stent before or after the stent is operated on the lesion, thereby effectively preventing a re-stricture from occurring at the lesion operated by the stent.
