Among the 282 studies in Colorectal Neoplasms with a site in Korea, Republic of, from their registry updates:
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.
This study aims to demonstrate that removing the urinary drain immediately after colorectal cancer surgery is non-inferior to removing it on the first day (within 24 hours) after surgery in terms of the incidence of acute urinary retention.
To evaluate the non-inferiority of the incidence of acute urinary retention (AUR) according to the timing of urinary drain removal after surgery.
Secondary outcomes are the incidence of symptomatic urinary tract infection (UTI), postvoid residual (PVR), length of hospital stay, postoperative pain score, and narcotic analgesic usage, early ambulation success rate, postoperative complication rate, and overactive bladder symptom assessment score for patient discomfort, etc., and to compare the clinical outcomes after surgery from various perspectives.

A urinary catheter is removed immediately after surgery and before general anesthesia wears off,
Device: Immediate urinary catheter removal
A urinary catheter is removed in the ward within postoperative 1 day (within 24 hours after surgery).
Device: urinary catheter removal within postoperative 1day
A urinary catheter is removed immediately after surgery and before general anesthesia wears off in the operating room.
The urethral catheter will be removed in the ward within 1 day after surgery (within 24 hours after surgery).
Incidence of acute urinary retention due to failure to void spontaneously within 4 hours after removal of a urinary drain
\- Definition of acute urinary retention: Failure to urinate spontaneously within 4 hours after removal of the urinary drainage tube or occurrence of residual volume greater than 400 ml as measured by ultrasound
Time frame: 3 days after surgery
Incidence of urinary drainage tube reinsertion rates
The rate of re-insertion of a urinary catheter due to failure of self-voiding at 4 hours after surgery and re-evaluation 4 hours later according to the protocol
Time frame: 7 days after surgery
Incidence of symptomatic urinary tract infections (UTIs)
Bacterial identification rate of 10\^5 CFU/mL or higher in urine culture test with clinical symptoms
Time frame: 30 days postoperatively
postoperative pain scores
Visual analog scale (VAS) score at 4±2 hours, 24±6 hours, and 48±6 hours after surgery. The NRS is a single-item scale in which patients choose a number from 0 to 10 that best represents their pain intensity, with 0 indicating no pain, 1 to 3 indicating mild pain, 4 to 6 indicating moderate pain, and 7 to 10 indicating severe pain .
Time frame: 3 days after surgery
Postoperative narcotic analgesic use rate
Rates of narcotic analgesic use at 4±2 hours, 24±6 hours, and 48±6 hours postoperatively
Time frame: 3 days after surgery
early walking success rates
Success rate of walking for more than 15 minutes three times a day at 4±2 hours, 24±6 hours, and 48±6 hours after surgery
Time frame: 3 days after surgery
postoperative complications
Charlson comorbidity index (CCI) score within 1 month of discharge from surgery. The CCI is based on the Clavien system but accounts for all accumulated complications and provides a continuous overall score between 0-100. The higher the score, the worse it is.
Time frame: 30 days after surgery
Evaluation of patient symptom and quality of life
Comparison of overactive bladder symptom assessment scores. Patient evaluation is performed using the Overactive Bladder Questionnaire (OAB-q short form) questionnaire. It consists of 19 items, each item is evaluated from 1 to 6 points, and the total score is 114 points. A higher score indicates more discomfort from overactive bladder.
Time frame: 30 days after surgery

Started Dec 2024 (actual). Primary completion is estimated for Dec 2026, 24 months after the start.
Of 898 non-industry interventional studies with no phase under Colorectal Neoplasms, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 62. This study's planned 24 months is below that.
Counting every sponsor, half of 955 studies reached it within 32 months; a quarter within 14 and three quarters within 60.
