Case Discussion

This is an example of a magnetic polyurethane (PUR) ureteral stent. The stent has a magnet at the bladder end to aid outpatient and non-theater removal with the use of a magnetic retrieval device. The retrieval device is usually inserted through the urethra and locks onto the stent magnet and the stent is easily removed in this manner. This particular stent is known as the Urotech Magnetic Black-Star ureteral stent.

As the stent has a magnet at the bladder end they are obviously MRI unsafe.
