Glow-in-the-Dark dye could prevent surgical accidents
NCT ID NCT05999747
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a dye called ASP5354 that makes the ureter glow under special cameras during abdominal surgery. The goal is to help surgeons avoid accidentally cutting or damaging the ureter, a rare but serious complication. 95 adults with normal or impaired kidney function received the dye, and surgeons compared visibility under normal light versus the glow mode. The trial is complete, and results will show if the dye improves ureter visibility.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- ASP5354 (a medical dye injected into the bloodstream to highlight the ureter during surgery)
- What this could lead to
- If successful, this dye could become a standard tool to help surgeons avoid accidentally injuring the ureter during abdominal surgeries.
- What could go wrong
- This is a completed phase 3 trial with only 95 participants, so results may not apply to all patients or surgeries. The dye's effectiveness depends on the imaging equipment and surgeon skill.
