Comparing Immediate Removal and Postoperative 1 Day of Urinary Catheter After Colorectal Cancer Surgery

The enhanced recovery after surgery (ERAS) program is widely applied in colorectal cancer surgery. Among the early recovery programs after surgery, the timing of removal of the urinary catheter after surgery has been emphasized recently, but the specific timing is still under discussion. Maintaining the urinary catheter after surgery is to prevent urinary retention after surgery, but it is known that the risk of urinary tract infection increases the longer it is maintained. Previously, it was removed 3 days after colorectal cancer surgery, but several studies reported that even if it was removed earlier, the incidence of urinary retention did not increase, and rather the incidence of urinary tract infection decreased. In particular, by applying the early recovery program after surgery, factors related to patient recovery before, during, and after surgery are applied to help rapid recovery, and it has been reported that early removal of the urinary catheter has a positive effect on postoperative recovery and complications. Therefore, it is necessary to prove that the timing of removal of the urinary catheter after surgery in colorectal cancer patients can help early recovery through clinical results such as patient recovery and occurrence of complications.
