Conditions
Brief summary
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
Interventions
NIRS measurements will be performed on each testicle on a group of healthy boys and on a group of boys under 18 years consulting to emergency for scrotal pain

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| mean tissue oxygenation percentage (NIRS measurements) of the testicles for healthy boys | one day | Near-infrared spectroscopy (NIRS) is a noninvasive technology that continuously monitors regional tissue oxygenation. Originally used for assessment of oxygen saturation of the brain, its use has now been expanded to evaluation of oxygenation of tissues other than the brain. Normal values for NIRS values are between 60-75% but physiological values of 55-60% have been reported in some cardiac patients |
| mean tissue oxygenation percentage (NIRS measurements) of the both testicles for boys with scrotal pain | one day | Near-infrared spectroscopy (NIRS) is a noninvasive technology that continuously monitors regional tissue oxygenation.
