Catheter timing could cut infections and speed recovery after colorectal surgery
NCT ID NCT06769087
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This trial tests whether removing the urinary catheter immediately after colorectal cancer surgery (before anesthesia wears off) is as safe and effective as removing it the next day. The goal is to lower the risk of urinary tract infections and help patients recover faster. About 316 adults undergoing colorectal cancer surgery will be randomly assigned to one of the two timing groups, and researchers will track urinary retention, infection rates, and the need for catheter reinsertion.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- urinary catheter removal timing (immediate vs. postoperative day 1)
- What this could lead to
- If removing the catheter immediately after surgery proves safe and effective, it could become a standard practice to reduce urinary tract infections and help patients recover faster after colorectal cancer surgery.
- What could go wrong
- This is a single-center trial with 316 participants, so results may not apply to all hospitals or patients. Removing the catheter too early may increase the risk of urinary retention requiring reinsertion.

Inclusion Criteria: * 19 years old 80 years old * Patients diagnosed with colorectal cancer who are eligible for radical resection surgery * Patients who underwent open, laparoscopic, or robotic surgery * Written informed consent Exclusion Criteria: * Patients who have undergone two or more major abdominal surgeries, including lateral pelvic lymph node dissection, at the same time * Patients who require continuous monitoring through a urinary catheter due to hemodynamic instability or massive bleeding, etc. * Patients who have undergone conventional treatment in cases other than distant metastasis or R0 resection * Patients who have developed complications related to the urinary system during surgery and require maintenance of a urinary catheter such as a urethral stent * Patients who have undergone urinary surgery such as urethral stent placement, cystectomy, or urostomy in the past * Patients who are on hemodialysis or peritoneal dialysis due to chronic renal failure * Patients who cannot participate in a clinical trial at the discretion of a physician * Patients who do not wish to participate in the study
