Presentation
The patient was post laparoscopic vesicovaginal fistula repair with bilateral ureteric stents insitu. Request for cystogram to exclude persistent fistula prior to stent removal.
Patient Data
Control x-ray of the abdomen prior to cystogram demonstrates bilateral ureteric stents (double J) in situ. The distal bladder ends have a dangling radiopaque magnet, stuck together in this instance. There is a urethral catheter in situ.
Photographs of the ureteric stents and retrieval device. The stents have a dangling magnet and the retrieval device also has a magnet to aid removal. The stents have markings to aid positioning and deployment.

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.
