Acute Testicular Torsion: Presentation and Diagnosis

Testicular torsion is the most common pediatric urologic emergency and is a common cause of acute scrotal pain. Timely diagnosis is important for testicular salvage,as treatment delayed beyond 6 hours from the onset of symptoms is the most predictive factor of testicular death. There is a bimodal distribution of age with extravaginal torsion most commonly presenting in the neonatal period and intravaginal torsion most commonly presenting around the onset of puberty. Intermittent testicular torsion presents a unique challenge in making an accurate diagnosis, as patients most often present when asymptomatic. Several risk factors exist, although bell-clapper deformity is the most important. The diagnosis is made largely on history or physical examination. In equivocal cases, imaging with color Doppler ultrasonography may be helpful in making the diagnosis. Additional tools including near-infrared spectroscopy and Testicular Workup for Ischemia and Suspected Torsion score may be helpful in diagnosing testicular torsion. Possible long-term effects on fertility and hormonal function are also often a concern for the patient and clinician. This review contains 6 figures, 5 tables, and 34 references.
