New dye test could save testicles and spare thousands of boys from needless surgery

This study tests a new imaging method using a safe dye called indocyanine green (ICG) to quickly tell if a child's testicular pain is due to torsion (twisted testicle) or something else. About 85% of children who have surgery for testicular pain don't actually have torsion. The goal is to see if ICG imaging can accurately diagnose torsion during surgery, so no torsions are missed and fewer children have unnecessary operations. The study will include 107 children and young people aged 0-19.
