This invention relates to a urinary catheter for post-prostatectomy, comprising an outer sheath, a catheter disposed inside the outer sheath, and an expansion component disposed on the surface of the outer sheath. Compared with the prior art, this invention, through the protruding structure on the surface of the balloon, allows the doctor to achieve hemostasis on the wound after prostatectomy via the balloon. The protruding structure can closely fit the uneven interior of the wound after surgery, resulting in better hemostasis compared to the smooth balloon surface in the prior art. At the same time, since the interior of the protrusion is connected to the interior of the balloon, the expansion size of the protrusion during the balloon inflation phase can be affected by the unevenness of the wound surface, avoiding excessive pressure on the post-operative wound area. In addition, the design of multiple sub-protrusions can increase the contact area after the balloon is filled with water or air, resulting in better compression hemostasis.
