Testicular torsion occurs when the spermatic cord twists, cutting off blood supply to the testicle. It is a urological emergency requiring surgery within hours to save the affected testicle.
Testicular torsion occurs in approximately 1 in 4,000 males under age 25 per year, with peak incidence during adolescence (ages 12-18). A second, smaller peak occurs in neonates. It accounts for approximately 25-35% of acute scrotal presentations in children and adolescents.
The condition occurs when the testicle rotates on the spermatic cord, twisting the blood vessels that supply it. Without prompt intervention, the testicle becomes ischemic (blood-starved) and may ultimately die. The degree of torsion and duration of ischemia determine the outcome.
The testicular salvage rate is approximately 90-100% if surgery is performed within 6 hours of symptom onset, dropping to approximately 50% at 12 hours and below 10% after 24 hours. This makes it a true surgical emergency.
An anatomical variant called the 'bell-clapper deformity,' where the tunica vaginalis attaches high on the spermatic cord allowing the testicle to rotate freely, is present in approximately 12% of males and predisposes to torsion.
People with Testicular Torsion often experience the following symptoms.
Abrupt onset of intense, unilateral scrotal pain, often waking the patient from sleep. The pain may radiate to the lower abdomen and groin.
The affected side of the scrotum becomes swollen, red, and tender. The testicle may appear to ride higher than the contralateral side (high-riding testis).
The cremasteric reflex (contraction of the cremaster muscle when the inner thigh is stroked) is typically absent on the affected side. This is a useful clinical sign.
Systemic symptoms of nausea and vomiting are common due to the severity of the pain and may be the presenting complaint in younger children who cannot localize pain.
Certain factors may increase your likelihood of developing Testicular Torsion.
Common approaches to managing testicular torsion. Always consult a healthcare provider for personalized treatment.
The spermatic cord is untwisted and the testicle is assessed for viability. If viable, it is fixed to the scrotal wall (orchiopexy) to prevent recurrence. Surgery should occur as quickly as possible.
Both testicles are typically fixed during surgery, as the bell-clapper deformity that predisposes to torsion is usually bilateral. This prevents future torsion on either side.
A physician may attempt to manually untwist the testicle as a temporizing measure while awaiting surgery. This should not delay surgical exploration. The classic maneuver involves rotating outward ('open the book').
If the testicle is found to be non-viable at surgery (necrotic), it must be removed to prevent infection and immune-mediated damage to the remaining testicle.
Diagnosis is primarily clinical based on sudden onset of severe testicular pain with a high-riding, tender testicle and absent cremasteric reflex. Color Doppler ultrasound can confirm reduced or absent blood flow, but surgery should not be delayed for imaging when clinical suspicion is high.
Seek emergency medical care immediately for sudden, severe testicular pain. Testicular torsion requires surgical treatment within 6 hours for the best chance of saving the testicle. Do not wait for pain to subside.
Steps that may help reduce the risk of developing or worsening testicular torsion.
No reliable prevention method exists
Surgical fixation (orchiopexy) of the contralateral testicle during torsion repair
Prompt medical attention for any acute testicular pain
Education of adolescent males about emergency signs
If left untreated or poorly managed, testicular torsion may lead to:
The testicle can typically survive 4-6 hours without blood flow. Salvage rates are highest within 6 hours and drop significantly after 12 hours. This is why it is a true emergency.
Without orchiopexy (surgical fixation), there is a significant risk of recurrence. Bilateral fixation during initial surgery prevents torsion on both sides.
If treated promptly and the testicle is saved, fertility is usually preserved. Even if one testicle is lost, the remaining testicle typically provides adequate hormone production and fertility.
