The Cascade Ureteral Stent CAS70VR is a sterile, single-use, double pigtail ureteral stent manufactured by Dornier MedTech. Designed to relieve ureteral obstructions caused by stones, strictures, malignancies, or trauma, the stent is constructed from a thermoplastic polyurethane elastomer compounded with barium sulfate for radiopacity under fluoroscopy. Its hydrophilic coating facilitates smooth insertion, while the double pigtail design secures the stent in place within the urinary tract, minimizing migration and maximizing patient comfort. The stent is available in a range of diameters (4.9–8.0 Fr) and lengths (14–32 cm), with the CAS70VR model typically indicating a 7 Fr diameter and 28 cm length, though specific dimensions should be confirmed per packaging or manufacturer data.

• Key Features:
• Double Pigtail Design: Prevents migration and ensures secure placement in the renal pelvis and bladder.
• Hydrophilic Coating: Reduces friction for easier, less traumatic insertion.
• Radiopaque: Barium sulfate compounding allows clear visualization under X-ray or fluoroscopy.
• Graduation Marks: Aid in accurate stent positioning during placement.
• Drainage Holes: Along the stent and at both pigtail ends for optimal urine drainage.
• Monofilament Tether: Attached to the proximal (bladder) end for easy repositioning and removal.
• One-Step Insertion System: Includes a pigtail straightener for simplified placement over a guidewire.
• Sterile and Single-Use: Packaged sterile for patient safety; labeled for a maximum 30-day indwell time.
• Indications: Relief of ureteral obstruction from stones, strictures, malignancies, trauma, or in conjunction with ESWL (extracorporeal shock wave lithotripsy)
