The utility model discloses a ureteral stent and a ureteral stent device using the ureteral stent. The ureteral stent comprises a stent main body, and a pull line which consists of an elastic section and a magnetic absorbing section, wherein one end of the elastic section is fixedly connected with the tail of the stent main body while the other end thereof is fixedly connected with the magnetic absorbing section; the elastic section is an elastic silk yarn, and the magnetic absorbing section is a yarn with a discontinuous iron core; when the elastic section is freely expanded, the length of the pull line is shorter than the distance from the urethral orifice of a patient to the tail of the stent main body of the ureteral stent implanted into the human body of a patient. In case the ureteral stent is to be taken out, the magnetic absorbing section can be outwards attracted via a magnet, so that the elastic section is extended, the pull line is exposed outside the human body, and then the ureteral stent can be taken out by pulling the pull line. Compared with the prior art, the ureteral stent disclosed via the utility model solves the problem that the pull wire may lead to infection of a patient after being polluted due to exposed outside, as well as the problem that the patient not feels good because of the pull line exposed outside.
