UroFlow Ureterstents

UroFlow Ureterstents

Diese biokompatiblen Stents wurden entwickelt, um einen ungehinderten Harnfluss zu gewährleisten. Sie bieten eine zuverlässige Unterstützung für die Harnleiter und fördern die Heilung und den Komfort bei der Behandlung urologischer Obstruktionen.

Informationen

UroFlow offers a comprehensive portfolio of polyurethane (PUR) ureteral stents designed to address diverse clinical indications for ureteral drainage. By leveraging biocompatible PUR—sometimes treated with phosphorylcholine (PC)—the UroFlow lineup ensures minimal encrustation, enhanced patient comfort, and safe long-term indwelling. With multiple colors signifying distinct features, each stent configuration tailors to specific patient or procedure needs.

Yellow Stents
  • Gentle on Tissues: Flexible, smooth material reduces trauma during placement and long-term indwelling, enhancing patient comfort.
  • Durable & Resistant: Maintains structural integrity under continuous drainage conditions.
  • Secure, Kink-Resistant Drainage: Resilient design prevents catheter collapse in tortuous renal pathways or while navigating challenging anatomical angles.
  • Robust Performance: Maintains uninterrupted flow, limiting the risk of catheter occlusion or displacement.
  • Marked with Radiopaque Bands: Ensures consistent fluoroscopic or ultrasound visibility for precise, real-time positioning.
  • Graduated Depth Markings: Facilitates accurate placement in the renal collecting system, reducing repeated repositioning attempts.
  • Adaptable to Various Patient Profiles: Multiple pusher lengths accommodate deeper or more proximal access routes, supporting diverse procedural needs.
  • Ease of Use: Simplifies advancement and stabilization in extended or anatomically complex drainage paths.

UroFlow Design & Material Highlights

Polyurethane (PUR)
  • Aliphatic PUR: Tailored for medical applications, demonstrating minimal blood cell adhesion and low-grade inflammatory response.
  • Temperature Responsiveness: Softens at body temperature, reducing potential trauma and facilitating comfortable stent dwell.
  •  
  • Anti-Encrustation: Diminishes bacterial colonization and crystal formation, enabling long indwelling periods without frequent stent changes.
  • Enhanced Biocompatibility: Lowers infection incidence and fosters tissue compatibility during extended implantation.
  •  
  • Durability in Moist Environments: PUR’s thermoplastic properties and PC layering allow stents to remain for several months if clinically necessary.
  • Regular Follow-Up: Despite robust design, routine imaging or endoscopic evaluations ensure timely detection of encrustation or displacement issues.

ASTM F-1828 Compliance: Stent shaft length is indicated without including the pigtail J-tip, ensuring standardized measurement references.

Klinische Vorteile und Anwendungen

Vielseitige Indikationen

  • Obstructive Uropathy: Stents maintain or re-establish urinary flow in cases of kidney stones, strictures, or other obstructive processes.

    • Post-Surgical Support: Aids in healing after urological interventions or reconstructive procedures, preventing complications like edema-induced obstruction.
  • PUR’s Low Thrombogenicity: Reduces inflammatory reactions, providing safer long-term placement with less patient discomfort.
  • Controlled Micro-Environment: PC-treated surfaces (Yellow stents) offer an even gentler interface with mucosal surfaces.
  •  
  • Softening at Body Temperature: Decreases friction against ureteral walls, diminishing pain or irritation symptoms during stent dwell.
  • Green Series: Specifically formulated for especially sensitive patients requiring extra softness.
  •  

  • Magnetic Option (Black Series): Potential specialized removal technique in certain clinical protocols—subject to localized usage guidelines.

    • Standard White or PC-Coated Yellow: Simple stent exchange or replacement under standard endoscopic practices.
