Catheter out days earlier? new study tests safety after fistula surgery
NCT ID NCT05235204
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at whether removing a bladder catheter just 2 to 3 days after surgery to repair a colovesical fistula (an abnormal connection between the colon and bladder) is safe. Normally, the catheter stays in for about 10 days. Researchers compared 65 adults who had early removal to historical data from patients who had later removal. The goal was to see if early removal leads to urine leaks or other complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- early removal of Foley catheter (procedure)
- What this could lead to
- If successful, this could allow patients to have their bladder catheter removed sooner after surgery, reducing discomfort and recovery time.
- What could go wrong
- This is a small, single-center study comparing results to historical data, not a randomized trial. Early removal might increase the risk of urine leaks or need for re-insertion.
