Novel ureteral stent

A novel ureteral stent used for drainage of a stoma of a ureter comprises an outer drainage part and an inner drainage part which are communicated with each other, wherein the inner drainage part adopts a tubular structure, and the outer drainage part adopts an eversible, folded and extended horn-shaped structure. The ureteral stent can effectively expand narrow ureter stoma, fully expand and support the lower ureter for urine drainage to effectively prevent upper urinary tract from infection and calculus generation, and bring convenience in stoma self-care of the patient; and related complication on the ureteral stent is obviously reduced, so as to greatly improve the life quality of the patient.
