Design: A ureteral stent is basically a hollow catheter with multiple side holes.
Material: At present, the ureteral stent is mainly made of silica gel, which has the characteristics of inertness, flexibility and elasticity.
Coatings: Ureteral stents often have surface coating materials that improve stent function, improve patient tolerance, and reduce complications.
Shape: The ureteral stent is crimped at both ends to limit its movement in the body.
