Area of Science:

  • Biomaterials Science
  • Medical Device Technology
  • Urology

Background:

  • Indwelling ureteral stents are crucial in urological procedures.
  • Stent-related complications include infection, encrustation, and biofilm formation.
  • Current materials face limitations in long-term efficacy and patient comfort.

Purpose of the Study:

  • To review technological advances and research in ureteral stent materials.
  • To discuss strategies for mitigating stent-related complications.
  • To highlight areas for future research in ureteral stent development.

Main Methods:

  • Literature review of recent in vitro and in vivo studies.
  • Analysis of biomaterial properties, coatings, and antimicrobial adsorption.
  • Examination of factors contributing to encrustation and bacterial biofilm formation.

Main Results:

  • Focus on developing materials to reduce encrustation and biofilm.
  • Antimicrobial adsorption shows promise but faces challenges with resistance and leaching.
  • Understanding encrustation factors is key to improving long-term use.

Conclusions:

  • Novel biomaterials and coatings are essential for advanced ureteral stents.
  • Strategies to combat infection and encrustation require further investigation.
  • Future research should prioritize biocompatibility and reduced complication rates.
