The goal of this observational study is to assess the diagnostic concordance between testicular Doppler ultrasound of the spermatic cord vessels performed by an emergency physician and the diagnosis of testicular torsion made by the urologist during an exploration in the operating room (Gold standard) in men patients between 16 to 70 years old with suspicion of testicular torsion.

Participants will receive ultrasound performed by emergency physician during their visit to the emergency department. Results of this exam will be compare to gold standard. If the results are consistent, the investigators will have demonstrated the value of integrating ultrasound by the emergency physician into the management of testicular torsion.
