Ureteral Stent Set

This medical device is a sterile, single-use, double pigtail (J) ureteral stent designed to provide an optimal balance of flexibility and radial support for safe, long-term and medium-term indwelling use. Constructed from a proprietary biocompatible polymer, the stent features a hydrophilic coating to facilitate effortless insertion and reduce friction against the ureteral mucosa, enhancing patient comfort during placement and throughout the indwelling period.

The dual-coil design ensures secure retention in the renal pelvis and the bladder, effectively preventing proximal or distal migration. The device is specifically indicated for the management of ureteral obstruction from various etiologies, providing a reliable conduit for urinary diversion to bypass blockages. In postoperative care, it serves a critical role following endoscopic procedures, laser lithotripsy, or percutaneous nephrolithotomy for renal and ureteral calculi, maintaining ureteral patency and allowing for the passive dilation of the ureter to facilitate the passage of edematous tissue or residual stone fragments.

Furthermore, the stent is essential for the gradual dilation of ureteral strictures and for providing structural support during ureteral anastomosis healing in reconstructive urological surgeries. By ensuring consistent internal drainage, it effectively promotes the reduction of hydronephrosis, protects renal function, and supports postoperative rehabilitation. The device is radiopaque for easy visualization during follow-up and is engineered to resist encrustation, thereby ensuring reliable performance for the intended indwelling duration.
