What is a scrotal ultrasound?

Ultrasound uses sound frequency to produce images which are viewed on a monitor. Physicians frequently use ultrasound in the office setting to view internal organs for to assess whether or not any abnormality/disease exists. Ultrasound of the scrotum is the primary method used to evaluate disorders of the testicles and the surrounding tissues as this test is not invasive, easily performed, and involves no radiation.

When is a scrotal ultrasound used?

Scrotal ultrasound is indicated for acute scrotal pain, absent or undescended testicles, inflammation, and for the evaluation of a testicular mass or scrotal swelling. It is also used to diagnose testicular torsion, a condition that occurs when the spermatic cord containing the blood vessels that supply the testicles twists and thereby diminishes the blood flow to the testicle.

The patient lies on his back on an exam table. A rolled towel is placed between the patients legs to support the scrotum. The penis is lifted up onto the abdomen and covered. A gel that enhances transducer contact with the skin is placed on the scrotum and the ultrasound transducer is positioned gently onto the scrotum. As the transducer is moved over the scrotum, images are created, viewed, and interpreted by the physician. The exam takes approximately 15-30 minutes.
