Unexplained testicular pain is commonly seen in patients with testicular torsion, which usually develops at rest, usually at night when the patient is asleep, and will present with pain in the testicles, and a careful examination of the patient’s scrotum will reveal an upward shift in the position of the testicles, a change in the position of the testicles, and symptoms of pain. Testicular torsion will cause testicular ischemia, and severe patients may cause testicular ischemia and necrosis, so the possibility of testicular torsion must be highly suspected after the discovery of testicular pain, and it is necessary to go to the urology department as soon as possible to make a clear diagnosis through the scrotal ultrasound examination. For patients who are found in time, it can be repositioned by manipulation or surgical repositioning, thus avoiding the possibility of testicular excision due to ischemia and necrosis.
