New laser microscope could spot urinary tract tumors without needles
NCT ID NCT02276924
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a laser confocal microscope, used during a kidney-ureter scope procedure, can tell the difference between normal and cancerous tissue in the upper urinary tract. 29 adults with conditions like blood in urine, kidney stones, or urinary tract cancer took part. The goal was to see if this imaging method could reduce the need for biopsies, which can be difficult and risky.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- fluorescein (a dye used to highlight cells during imaging)
- What this could lead to
- If successful, this imaging technique could help doctors identify tumors during a scope procedure without taking tissue samples, making diagnosis safer and faster.
- What could go wrong
- This is a small, completed study with only 29 participants, so results may not apply to everyone. The technique is still experimental and may not be accurate enough to replace biopsies.
