Stent removal in an easy way

Our Various Magnets

Bicompatible, thread-anchored magnet at the pigtail-end on the bladder side.

Magnetic Sizes:

The magnet size is selected after choosing the insertion technique and evaluating the patient’s anatomical conditions.

  • Magnet size XS: 4, 8 FR/ 3,5mm Magnet-Length 
  • Magnet size S: 7 FR/ 3,5mm Magnet-Length 
  • Magnet size L: 9 FR/ 4,5mm Magnet-Length


The advantages in the removal of the Magnetic Black-Star®

Benefits for patients:

  • Easy & fast removal (1,2)
  • No second anaesthesia required
  • Improved Patient compliance (2)
  • Less pain compared to cystoscopy (4)

Benefits for institutions & users:

  • Free operating room capacity since no new anaesthesia is necessary (2)
  • Quick & easy removal, e.g. by the nursing staff (1,3)
  • Saving resources – cost & time efficiency (2)
  • No instrument preparation necessary


Ureteral Stents for Children:

A study by the renowned urologist Dr. Thomas Blanc shows the clinical benefits of Magnetic Black-Star®. 

Why is stent removal an increased risk when performed in children?

In addition to stent placement, stent removal in children poses challenges for urologists. In this case, the stent must be removed under general anaestheisa by cystoscopy. This is time-consuming and costly. For children, the repeated surgical experience is emotionally stressful and the repeated general anaesthesia carries the neurotoxicity risks described in the technical literature.

The solution? – The Magnetic Black-Star®

“Our study shows that the concept of a magnetic ureteral stent in children is successful and offers great advantages for patients, families and medical institutions”.
