Ureteral Stents

Core Features: Made of flexible biocompatible polymer with double coiled atraumatic ends and unobstructed inner lumen. Excellent shape retention and drainage performance.

Core Functions: Indwell in ureter to maintain normal urinary flow, prevent postoperative stricture, obstruction and hydronephrosis after lithotripsy or ureteral surgery.

Double-J Ureteral Stent (Double Pigtail Stent)

The Double-J Ureteral Stent is a classic indwelling drainage stent widely used in urology. Both ends adopt symmetrical J-shaped (pigtail) curled design, which can be firmly anchored in the renal pelvis and bladder respectively to effectively prevent stent migration and dislodgement. Manufactured from medical polymer with high biocompatibility, the stent features excellent flexibility, kink resistance and anti-incrustation performance. Multiple drainage side holes are evenly arranged on the tube body to ensure efficient urine drainage. Selected models are equipped with long-acting hydrophilic coating to reduce insertion friction, improve procedural smoothness and enhance post-operative patient comfort. The radiopaque body delivers clear fluoroscopic visibility for intra-operative positioning and post-procedural follow-up. It is mainly applied to relieve urinary tract obstruction, support ureter after surgery, drain urine and facilitate residual stone clearance, serving as an essential device for urinary calculi, strictures, tumors and various urological post-operative care.
