Thirsty after surgery? new study says a sip of water might be safe and soothing
NCT ID NCT07563530
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether giving patients small sips of water soon after urological endoscopic surgery can reduce thirst and improve satisfaction. Two hundred adults will either receive early oral hydration or standard care. Researchers will measure thirst levels, comfort, and any side effects like choking or vomiting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- water (early oral hydration)
- What this could lead to
- If it works, this could lead to a simple, low-cost way to reduce thirst and improve comfort after urological procedures.
- What could go wrong
- This is a small, early-stage trial with only 200 participants, so results may not apply to all patients. There is a small risk of choking or vomiting when drinking soon after surgery.
