Summary

This study tested a dye called IS-001 that is injected into the bloodstream to make the ureters (tubes from kidney to bladder) glow under special imaging during robotic gynecological surgery. The goal was to help surgeons see the ureters more clearly and avoid accidentally injuring them. The trial involved 189 women aged 16-75 scheduled for robotic surgery. Results compared visibility with the dye versus standard white light.
