| description | The invention provides a degradable ureteral stent and a preparation method thereof.The preparation method includes the steps that a glycolide monomer and an epsilon-caprolactone monomer serve as raw materials and are subjected to a polymerization reaction to obtain a prepolymer A, and then 1, 10-decanediol and citric acid serve as raw materials and are subjected to a polymerization reaction to obtain a prepolymer B; then mixing the prepolymer A and the prepolymer B, and carrying out cross-linking polymerization to obtain polyester; then taking polyester and dimethyl pyridine amine as raw materials to obtain modified polyester; and finally, mixing the modified polyester with the nanoparticles to prepare a water-in-oil emulsion, and carrying out extrusion type 3D printing. The degradation time of the ureteral stent is controllable, and the ureteral stent has a shape memory function and a good clinical application prospect.
