After total excision of bladder cancer, the bladder loses the function of storing and urinating and has to be hung with a urine bag; in addition, there may be accumulation of blood and fluid on the traumatic surface, which needs to be drained, and the urine bag can be used to collect the draining fluid. As the bladder has the function of urine storage and urinary drainage, its storage and urinary drainage will be subject to normal nerve innervation, which is coordinated by the smooth muscle of bladder and urethra, and the transverse muscle of pelvic floor. After total resection of bladder cancer, these two functions are lost, and the body has no way to store and urinate normally, so a urine bag needs to be attached to collect urine. In addition, a small amount of blood and fluid can exist in the abdominal cavity after surgery, which can cause infection, slow wound healing, indigestion, etc. if not drained in time, and need to be drained to appear, and the urethra can be used to collect the drainage fluid; in addition to observing whether there is any blood seepage from the wound. When hanging the urine bag, patients should pay attention to the position of the urine bag should not be higher than the bladder, so as not to cause urine reflux occurs, triggering infection. And regularly to the hospital to change the bag. Patients should also drink more water to prevent stone formation and urinary tract infection, quit smoking and avoid alcohol, have regular work and rest, don’t stay up late, and keep a positive and optimistic mood. After total excision of bladder cancer, patients should go to the hospital for follow-up regularly to observe the recovery of the body.
