Could 3 days beat 14? new study tests shorter catheter use for sudden urinary blockage
NCT ID NCT07283484
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
Acute urinary retention (AUR) is a sudden inability to urinate, often due to an enlarged prostate. The RELIEF study compares removing the catheter after 3 days versus the usual 14 days in 478 men. All participants receive a catheter and prostate medication. The goal is to see if a shorter duration is equally successful at restoring normal urination, while reducing discomfort and complications.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
alpha-blocker medication (tamsulosin, silodosin, or alfuzosin)
What this could lead to
If successful, this could lead to shorter, more comfortable catheter use for men with acute urinary retention, reducing infections and improving quality of life.
What could go wrong
This is a mid-sized trial, and results may not apply to all patients. A shorter catheter duration might increase the risk of needing re-catheterization.
