Assessment of Near-Infrared Spectroscopy in the Diagnosis of Testicular Torsion in Children

jpedsurg.org

No rapid test to diagnose testicular torsion (TT) exists. The usefulness of trans-scrotal near-infrared spectroscopy (NIRS) remains to be proven in children. Here, we measured testicular oxygenation (StO2%) in children with unilateral TT and compared values to those measured in children with another cause of testicular pain and in control subjects.

In brief

This study evaluates trans-scrotal near-infrared spectroscopy (NIRS) as a potential rapid diagnostic tool for testicular torsion in pediatric patients by measuring testicular tissue oxygenation levels. Researchers compared StO2% values between children with confirmed testicular torsion, those with other causes of testicular pain, and healthy controls to determine the technology's clinical utility.

No rapid diagnostic test currently exists for testicular torsion in pediatric patients.
Trans-scrotal NIRS measures testicular oxygenation (StO2%) as a potential diagnostic tool.
Study compares StO2% in confirmed torsion cases vs. other causes of testicular pain and controls.
NIRS may offer non-invasive, objective assessment to differentiate torsion from other acute scrotal pathology.
