Clinical data indicate that testicular torsion is not uncommon and can occur from newborns to the elderly, but has the highest incidence in adolescents. Inadequate awareness of the disease or untimely consultation can cause a male to lose a testicle in a matter of hours. Even if the testicle can be saved without excision, the testicle can become atrophied due to prolonged ischemia, which can even affect the opposite testicle. The onset of testicular torsion is usually rapid, and the clinical manifestation is usually severe pain in the affected testicle and scrotum. The pain is initially confined to the scrotum, but then progresses to the lower abdomen and perineum, accompanied by vomiting, nausea or fever, and redness, swelling and pressure pain in the pubic area. As the spermatic cord is also twisted, the blood vessels in the spermatic cord are blocked and the testicle lacks blood supply. If left untreated, the testicle will develop ischemic necrosis, darken and gradually atrophy to the point of loss of function. The cause of testicular torsion – generally congenital malformation is the main cause, mostly bilateral. Testicular torsion can occur during exercise, trauma, or sleep due to stimulation of the levator muscle, resulting in a spiral shape of the levator muscle fibers. At the onset of puberty, torsion is more likely to occur due to abnormal testicular suspension and increased testicular weight. Although these people usually do not feel anything and it is difficult to detect abnormalities during examination, torsion can occur at any time. In particular, patients with cryptorchidism who have only one testicle are more prone to this condition due to the obvious abnormalities of the reproductive organs. If it occurs in a pediatric patient, the diagnosis is often more difficult. Generally, the pediatric patient will have unexplained anorexia and restlessness, and the condition usually develops faster, so parents often ignore it and delay treatment, thus causing unnecessary harm to the affected child. In everyday life, many men are paralyzed by testicular torsion, resulting in delayed treatment, and individuals may even lose their fertility as a result, resulting in lifelong misfortune. Therefore, adolescent men who suddenly develop scrotal swelling, pain, should consider the possibility of testicular torsion, to go to the regular hospital urology, male department in a timely manner.
