The indwelling pressure measuring and urethral catheterization device comprises a first urethral catheterization mechanism and a first pressure measuring film, wherein three channels of an integrated structure are arranged on the side, matched with the human bladder, of the first urethral catheterization mechanism, so that a first urethral catheterization cavity, a pressure measuring cavity and a water injection cavity which communicate are defined inside the first urethral catheterization mechanism, and the side, away from the human bladder, of the first urethral catheterization mechanism is of a split structure, so that a first urethral catheter, a pressure measuring pipe and a water injection pipe which are matched with the first urethral catheterization cavity, the pressure measuring cavity and the first air injection cavity are obtained; the first pressure measuring film is arranged on the pressure measuring pipe; a pressure measuring bubble and a water bag which are matched are arranged at the front end of the first urethral catheterization mechanism; and first notches are formed in the positions, matched with the pressure measuring bubble and the water bag, of the pressure measuring pipe and the water injection pipe. According to the indwelling pressure measuring and urethral catheterization device, the system applying the urethral catheterization device and the application method, complications caused by a traditional indwelling urethral catheterization technology to the bladder of a patient can be effectively avoided or relieved.
