In situ bladder surgery refers to in situ neobladder surgery. It requires an indwelling urinary catheter, an abdominal drain, a ureteral stent tube, and possibly a cystostomy tube. In the case of open surgery an abdominal drain is also placed. An abdominal drain facilitates the drainage of fluid that leaks out after surgery and prevents abdominopelvic fluid retention. A ureteral stent tube is also placed to ensure that the ureteral neobladder anastomosis is open. Some surgeons also place a cystostomy tube to help flush the bladder and prevent bowel mucus from blocking the catheter. Neobladder in situ surgery involves creating a new bladder with bowel in its original location after the bladder is removed. A urinary catheter should be left in place after in situ neobladder surgery to allow adequate drainage of urine, which is conducive to the healing of the anastomosis site of the new bladder as soon as possible. Before removing the urinary catheter, a cystogram should be done to make sure that the anastomosis is completely closed before the urinary catheter is removed. If the surgery is open, a urinary catheter and an abdominal drain should be left in place. An abdominal drain facilitates the drainage of oozing fluid after surgery and prevents abdominopelvic fluid collection. After in situ neobladder surgery, it is important to pay attention to local wound disinfection and dressing change, if discomfort occurs, it is recommended to inform the doctor as soon as possible to deal with it.
