Abstract
An ureteral stent comprises an elongated, flexible tubular member which has one end with a magnetically attractable tip. Both ends of the stent are preferably both set in the form of hooks. A method of removing the stent from the bladder of a patient comprises introducing a retrieving catheter with a magnet at its proximal tip into the urethra, advancing the proximal tip of the catheter into the bladder which is signalled by urine flowing into the catheter, catching the magnetically attractable tip of the stent with the magnet and removing the stent by withdrawing the catheter with the magnetically attractable tip of the stent held by the magnet of the catheter.
