Indication
• Malignant Ureteral Obstruction(MUO)
Features
Structure
• Triple layered construction
– The outer stent gives high friction coefficient to prevent migration
– Three(3) platinum radiopaque markers at each end of the stent
– PTFE(Teflon) membrane prevents tissue ingrowth
– The inner stent reinforces overall radial force
– Both ends have lower radial force and are encapsulated by PTFE to prevent reactive hyperplasia
Preloaded type delivery system
• Outer sheath: Metal braided tube contributes excellent pushability and trackability
• Radiopaque ring at outer sheath: Shows deploying progression
• Yellow marker: Cystoscopic marker to place the stent at the orifice border
• Inner stent: Reinforces overall radial force
• Three(3) Radiopaque markers: Fluoroscopic markers for accurate placement. Accordance with the stent loaded portion – Proximal, Center, and Distal
