Near Infrared Spectroscopy and Testicular Torsion in Children

Near Infrared Spectroscopy and Testicular Torsion in Children

NIRS estimates tissue saturation of oxygenation in tissue beds. Animals studies suggested that transscrotal NIRS measurements can quantify testicular hypoxia and differentiate between torsed and non torsed testicles. The results of human studies are not conclusive. The hypothesis is that the difference in NIRS values between torsed and healthy testicles would not be zero and that this difference would be zero in control group and that NIRS could help to detect rapidly a TT Testicular torsion (TT) is a functional emergency. The diagnosis is sometimes difficult to make. No paraclinical examination can eliminate it with certainty. The investigators aimed to evaluate the interest of transscrotal near-infrared spectroscopy (NIRS) for the diagnosis of TT of child
