The Cascade CAS7022 ureteral stent by Dornier MedTech is a sterile, single-use, double pigtail stent designed to relieve ureteral obstruction caused by stones, strictures, malignancy, trauma, or post-procedural swelling. Constructed from a radiopaque thermoplastic polyurethane elastomer and coated with a hydrophilic layer, this stent facilitates smooth, atraumatic insertion and secure positioning within the urinary tract. The double pigtail design anchors the stent in both the renal pelvis and bladder, minimizing migration and maximizing patient comfort. The CAS7022 model is sized at 7 French diameter and 22 cm length, making it suitable for a wide range of adult urological procedures.
