A long-term ureteral stent

The ureteral stent with phosphorylcholine (PC) treatment

YELLOW-STAR ureteral stents are treated with phosphorylcholine (PC), an endogenous substance that is found, for example, in the outer cell membrane of erythrocytes (red blood cells) and makes them hydrophilic towards their environment.

What is it about?

  • biocompatible protection of implants
  • neutralizes the pH-value on the surface of the stent
  • water molecules on the surface prevent biofilm formation

Your benefits with YELLOW-STAR

  • reduced urinary tract infections and enrustations(2)
  • 12 months indwelling time
  • significantly less biofilm formation(2)
  • cost efficiency
  • high patient comfort due to HybridPRO®Technology material

After just 60 minutes at body temperature, the material is 50% softer.(1)
