Comparing IV and oral hydration to prevent kidney injury after CT scans in severe kidney disease patients
Official title: Intravenous vs. Oral Hydration to Reduce the Risk of Post-Contrast Acute Kidney Injury After Intravenous Contrast-Enhanced Computed Tomography in Patients With Severe Chronic Kidney Disease (ENRICH): A Randomized Controlled Trial
Run by Odense University Hospital · NCT05283512 · Data updated 2026-11-12
This study is testing whether drinking fluids can be just as good as getting IV fluids to help prevent kidney injury in patients with severe kidney disease who are having a CT scan.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with an eGFR less than 30 mL/min/1.73 m2 who are scheduled for elective IV CECT.
✕Probably not a fit
Patients currently undergoing active dialysis treatment or those with acute kidney failure or severe infections may not benefit from this study.

What this trial studies
This trial evaluates the effectiveness of intravenous (IV) hydration versus oral hydration in preventing post-contrast acute kidney injury (PC-AKI) in patients with severe chronic kidney disease (CKD) scheduled for elective contrast-enhanced computed tomography (CECT). It is a pragmatic, single-centre, open-label, parallel-group non-inferiority randomized controlled trial conducted at Odense University Hospital. Participants will be randomly assigned to receive either IV hydration or oral hydration before and after the CECT procedure. The study aims to determine if oral hydration can be as effective as the standard IV hydration protocol recommended for high-risk patients.
Why it matters
Potential benefit: If successful, this study could provide a less invasive and more convenient hydration method for patients with severe chronic kidney disease undergoing CT scans.
How similar studies have gone: Previous studies have shown that oral hydration is non-inferior to IV hydration in patients with mild to moderate CKD, but this specific approach in severe CKD is novel and untested.
