After cystectomy, since the bladder has been removed, there is no need to keep a catheter, and urinary diversion is usually performed for urination, which include ileocystectomy, in situ cystectomy, ureteral skin fistula and so on. 1. Ileal cystectomy: After the bladder is removed, a 15cm long section of ileum is intercepted from the ileocecal part of the bladder at a distance of about 10cm, and then both ureters are anastomosed to the ileum near the closed end of the ileum at a distance of about 1cm, and the open end of the ureter is used to make a fistula in the middle of the abdominal line from the right anterior superior iliac spine to the umbilicus, and urine flows out through the fistula port in the abdominal wall through the ileum. 2. In situ cystectomy: after removal of the bladder using the ileum or colon, dissected and refolded U-shaped suture to form a bag, suture in the position of the urethra formed after removal of the bladder at the end of the urethra, the operation does not need to do a skin fistula, urine is still discharged through the urethra. 3. Ureteral skin fistula: after cystectomy, the ureter is cut off at the end of the connection with the bladder and removed from the abdominal wall through a small incision in the skin and sutured to the surrounding skin to form a fistula, so that the urine from the ureter is led out of the body through the skin stoma. After cystectomy should avoid wound infection, regular replacement of the stoma bag, can be appropriate to carry out some exercise, enhance physical fitness, but also need to pay attention to the postoperative regular checkups, discomfort, timely consultation, so as not to delay the condition.
