A scrotal ultrasound, also known as a testicular ultrasound, is a safe, non-invasive imaging test that uses high-frequency sound waves to create detailed images of the scrotum — the pouch of skin containing the testicles and surrounding tissues. It is commonly used to evaluate pain, swelling, lumps, or injuries in the scrotal area.
During the procedure, the patient lies on their back, and a water-based gel is applied to the scrotum. A handheld device called a transducer is gently moved over the area to send sound waves into the body. These sound waves reflect off the tissues and generate real-time images on a monitor.
Scrotal ultrasound helps diagnose conditions such as testicular torsion (twisting of the spermatic cord), epididymitis (inflammation of the epididymis), varicocele (enlarged veins), hydrocele (fluid buildup), hernias, and testicular tumors. It is often the first step in evaluating testicular problems.
The scan is painless, quick (usually 15–30 minutes), and does not involve radiation, making it very safe. It provides crucial information to help doctors determine the cause of symptoms and guide appropriate treatment or further testing if needed.
