Key Benefits

  • Triple Functional Role: Acts simultaneously as a nephrostomy drainage tube, a ureteral stent across the UPJ, and a re-entry tract holder.
  • Self-Retaining Malecot Wings: Expandable wings anchor securely inside the renal pelvis without requiring a balloon.
  • Maintains UPJ Patency: Distal extension maintains ureteropelvic junction alignment and heals strictures over the catheter bridge.
  • Secondary Access Tract: Keeps the percutaneous flank tract open, permitting easy re-entry for secondary nephroscopy if residual stone fragments remain.
  • High Drainage Volume: Large wing openings drain debris-filled or blood-tinged urine effectively.
