LAB TEST
Scrotal ultrasound
Scrotal ultrasound is an imaging test that looks at the scrotum. The scrotum is the flesh-covered sac that hangs between the legs at the base of the penis and contains the testicles. The testicles are the male reproductive organs that produce sperm and the hormone testosterone . They are located in the scrotum , along with other small organs, blood vessels, and a small tube called the vas deferens.
How the Test is Performed
You will lie on your back with your legs spread. The health care provider drapes a cloth across your thighs under the scrotum or applies wide strips of adhesive tape to the area. The scrotal sac will be slightly raised with the testicles lying side by side. A clear gel is applied to the scrotal sac to help transmit…
How to Prepare for the Test
No special preparation is needed for this test.
How the Test will Feel
There is little discomfort. The conducting gel may feel slightly cold and wet.
Why the Test is Performed
A testicle ultrasound is done to: Help determine why one or both testicles have become larger or smaller Look at a mass or lump in one or both of the testicles Find the reason for pain in the testicles Show how blood flows through the testicles
Normal Results
The testicles and other areas in the scrotum appear normal.
What Abnormal Results Mean
Possible causes of abnormal results include: Collection of very small veins, called a varicocele Infection or abscess Noncancerous (benign) cyst Twisting of the testicle that blocks blood flow, called testicular torsion Testicular tumor Testicular atrophy (shrinkage)
Risks
There are no known risks. You will not be exposed to radiation with this test.
Considerations
In certain cases, Doppler ultrasound may help identify blood flow inside the scrotum. This method can be helpful in cases of testicular torsion because blood flow to the twisted testicle may be reduced.
