The abdominal catheter is withdrawn after in situ cystectomy, and it can be removed generally if the patient can get out of bed and urinate on his/her own after the operation. After in situ cystectomy, the tube can be removed when the patient can get out of bed and urinate on his/her own, usually for 5~7 days. In some patients, the wound healing process is slow, and the time of removal is delayed for about 3~4 weeks. After surgery, patients need to observe the healing of the bladder wound and make sure that there is no fluid or exudate around the bladder before removing the drain. When some patients undergo prostate surgery, such as after prostatectomy, because of the need to use a thicker mass of tubes for compression to stop bleeding, it may be left in place for up to a week or even 10 days, and can only be removed when the urine is clear and bleeding has stopped. Withdrawal of abdominal catheters after in situ cystectomy depends on the patient’s recovery, and you can consult the relevant specialized doctors.
