Key Benefits

  • Biocompatible Material Formulations: Available in short-term polyurethane or long-term biocompatible polymers designed to resist encrustation.
  • High Flow Side Perforations: Lateral drainage holes along the entire body prevent blockage and support extraluminal and intraluminal flow.
  • Anti-Migration Pigtails: Dual memory coils lock securely into the renal calyx and vesical dome to prevent upward or downward movement.
  • Smooth Hydrophilic Coating: Reduces friction during placement over 0.035 in guidewires through narrow or edematous ureters.
  • Clear Centimeter Markings: Graduation lines along the stent body allow accurate positioning under direct endoscopic visualization.
