203 Series Disposable Ureteral Stent

Description :

After the RIRS or PCNL procedure, a temporary stent is mostly reserved for several weeks to guide the ureter drainage and stone discharging, to prevent the new stone formation.

  • Biocompatible polyurethane (PU) that softens >35% at body temperature, which will promote greater patient tolerability.
  • Hydrophilic surface that facilitates navigation of strictures.
  • Small holes on the stent walls to facilitate the drainage.
  • Graduated circumferential markings every 5cm along the stent body.
  • High retention pigtail shape tails reduces potential stent movement.
  • Tapered tips that facilitate accessing the ureteral orifice.
  • Clear development under fluoroscopy.

Stent Length Definition

  • it only refers to the effective length as photo below,

Type A Triangular Prism Stent

Triangle Prism structure design and concave surface.

  • Bigger space reserved between the stent and the ureter that promotes drainage.
  • Less contact between the stent and the ureter that will reduce the adhesion and facilitate ease of removal.

Type B Cylindrical Stent

  • Larger inner lumen and thinner stent wall design to promote the drainage.
  • Cylindrical body matching to the ureter reduces the foreign body sensation.
