Ureteral stent US series

polymerhydrophiliccoated

Product overview
EVT Class III ureteral stent set is manufactured from imported thermosensitive polymer with an optimized structural design. It is intended for urological use to relieve upper urinary tract obstruction and to provide postoperative support and drainage after stone removal. The device is designed for safe long-term indwelling up to 90 days and is compatible with a range of clinical procedures.

Key features & benefits

• Thermosensitive imported material increases softness by approximately 40% at body temperature to improve patient comfort during indwelling.
• Thin-wall, large-lumen design with ID/OD ratio up to 72% to optimize flow.
• Approximately 26% more side holes to enhance drainage efficiency.
• Balance of support strength and patency to maintain ureteral lumen while reducing irritation.
• Radiopaque markers for accurate intraoperative positioning.
• Class III medical device suitable for long-term indwelling (up to 90 days).

Clinical indications

• Temporary relief of ureteral obstruction due to inflammation or edema.
• Maintenance of ureteral patency and reduction of postoperative renal pelvic pressure.
• Effective urinary drainage to lower risk of postoperative infection.
• Facilitation of postoperative stone passage and improvement of stone-free rates.
• Ureteral support to promote tissue healing and establish a temporary drainage pathway.
