Urethral injury is generally divided into anterior urethral injury and posterior urethral injury. Urethral injuries usually have urethral bleeding, in which blood overflows from the external opening of the urethra after the anterior urethral injury, and the posterior urethral injury is likely to cause massive bleeding. However, due to urinary tract obstruction, there is generally no bleeding or only a small amount of blood flowing out of the external opening of the urethra. After bleeding from anterior urethral injury, it is necessary to immediately compress the perineum to stop bleeding, and conduct anti shock treatment, and perform surgery as soon as possible. Posterior urethral injury is likely to cause hemorrhagic shock, so it is necessary to establish an infusion channel in time, correct low blood volume, supplement whole blood or other blood substitutes, and operate as soon as possible. After the repair of urethral injury, it is possible for scar contraction to cause urethral stricture, and regular urethral dilatation after surgery may not be effective. In addition, infection and urinary fistula are also common complications.
