The urinary diversion method of abdominal wall stoma in patients after radical cystectomy for bladder cancer requires long-term hanging of urinary bag, and the quality of life is generally low. Currently, there are two ways of urinary diversion after radical cystectomy, one is to reconstruct a new bladder (in situ neobladder) through organs such as ileum and colon, and the other is to direct the ureter to the abdominal wall and connect the ureter to the abdominal wall incision through an abdominal wall stoma, and then the urine will be outflowed through the abdominal wall stoma, so it needs to be hung up with a urinary pouch in the long term. The first method is now the preferred method of bladder replacement because it does not require a hanging bag and the reconstructed bladder is closer to the natural bladder function, thus it is more widely accepted and the quality of life and psychological acceptance of the patients are higher. However, in situ neobladder has certain requirements for the patient’s own tumor. Urinary diversion abdominal wall stoma is mostly chosen for patients with severe bowel function, hepatic impairment, distant metastases, palliative total bladder removal, and short life expectancy of the patient, who need to wear a urine bag for a long time. It has been found that patients wearing urine bags for a long period of time have different degrees of obstacles in their sex life, sleep and social activities, and some patients also have serious mental disorders and social fears as a result. Therefore, the quality of life of patients wearing urine bags for a long time is generally low. To summarize, hanging urine bags after bladder removal will affect life.
