Could a coloring book calm nerves before prostate surgery? a trial puts mandala therapy to the test.
NCT ID NCT07723794
First seen Jul 23, 2026 · Last updated Jul 28, 2026 · Updated 3 times
Summary
This trial tests whether coloring mandalas for 20 minutes can lower anxiety, pain, and improve vital signs and satisfaction in men undergoing transurethral resection of the prostate (TURP). Half of the 64 participants will color a mandala before surgery; the other half will receive standard care. Researchers will measure anxiety, pain, and satisfaction after the procedure to see if this simple activity makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mandala coloring
- What this could lead to
- If effective, mandala coloring could offer a simple, drug-free way to reduce anxiety and pain before and after prostate surgery.
- What could go wrong
- This is a small, early-stage trial. The effect may be small or not generalizable, and coloring cannot replace standard medical care.
