What is the most sensitive physical finding for the diagnosis of testicular torsion?

• A. The alleviation of pain when the testis is elevated
• B. Pain lasting for hours or days
• C. Abnormal results of urine culture
• D. Absence of the cremasteric reflex

Answer: (D)

The most sensitive physical finding for testicular torsion is the absence of the cremasteric reflex. Normally, stroking the inner thigh causes the ipsilateral testicle to elevate; when torsion affects the testicle, this reflex is often lost on the affected side. Its absence strongly suggests torsion and should prompt urgent urologic evaluation and exploration to detorse and salvage the testis. The other options are less reliable: relief with elevation (Prehn sign) is not specific, pain lasting for hours or days isn’t typical of torsion (which is abrupt), and an abnormal urine culture points to infection rather than torsion.
