Background introduction of waist urine bag

After bladder cancer patients are hospitalized, a total cystectomy is usually performed in order to prevent their condition from getting worse. After cystectomy, urethral diversion is performed, and a fistula is performed on the patient's waist, which is to create a "nipple" on the surface of the human body to excrete human urine. During the patient’s hospitalization, a plastic catheter is usually inserted directly into the nipple by intubation. The catheter is inserted into the body, which is easy to cause wound infection and severe pain to the patient. After the patient is discharged, the external urine collection is generally used. In this way, urine is collected from the nipple on the surface of the body. At this time, the waist urine bag is used for extracorporeal urine collection, commonly known as the waist urine bag or the waist urine collector.
