A urethral stent (10) comprises an elongated, flexible tubular member which has a distal end (12) which is magnetically attractable. The proximal and distal ends (11, 12) are preferably set in the form of hooks (13, 14). A method of removing the stent from the urethra comprises introducing a retrieving catheter with a magnet at its tip into the urethra, catching the magnetically attractable distal end of the stent with the magnet and removing the stent by withdrawing the catheter with the distal end of the stent magnetically held by the magnet of the catheter. |
