Zusammenfassung:	The utility model discloses a urethra metal stent, which belongs to the field of urethra stents and comprises a nickel-titanium alloy main body formed by spirally surrounding, the middle of the nickel-titanium alloy main body is cylindrical, conical heads are arranged at two ends of the nickel-titanium alloy main body, and the conical heads and the nickel-titanium alloy main body are integrally designed. The outer surface of the conical head and the outer surface of the nickel-titanium alloy body are both coated with hydrophobic coatings. The nickel-titanium alloy main body is made of nickel-titanium alloy materials, the nickel-titanium alloy main body has high compression resistance, so that the device cannot deform due to compression of a cavity after being integrally implanted into the urethra, the two conical heads symmetrically arranged at the two ends of the nickel-titanium alloy main body form an integral support, the diameters of the two conical heads are large, and the diameter of each conical head i
