Summary

This study tests a non-invasive light-based device (SR-NIRS) to measure blood flow and oxygen in the testicles of children. It includes 74 boys aged 1 month to 18 years, both healthy and those with sudden scrotal pain. The goal is to see if this device can help tell if testicular torsion is present, potentially leading to faster diagnosis and treatment.
