Product Description
Advanced Double-J/Single-J ureteral stent system combining antireflux protection and enhanced drainage through an increased inner lumen. Designed for percutaneous nephrostomy and stone management procedures (PCNL) and hydronephrosis cases, with options for Double J, Single J and dedicated antireflux configurations.

Key Features

• Hydrophilic coating: Reduces insertion friction (approx. 0.03 friction coefficient)
• Integrated anti-reflux valve: Prevents retrograde urine flow
• Enlarged inner lumen: Approximately 30% larger than conventional stents for improved drainage
• Dual-function design: Enables simultaneous stone fragmentation and suction when used with the integrated kit

Complete Procedure Kit Includes

• Radiopaque stent (Double J / Single J options)
• Triaxial access system:
  • Dilator set
  • Peel-away sheath
  • Puncture needle
• Stone management components:
  • Negative pressure connector
  • Collection bottle with filter
• Pushers and clamps according to stent type and size

Clinical Advantages

• Simplified stone retrieval with integrated suction
• Reduced procedure time via simultaneous fragmentation and aspiration
• Lower insertion trauma and improved patient comfort due to hydrophilic surface
• Compatibility with standard PCNL instruments
