A testicular ultrasound is a painless and effective way to examine the testes, epididymis and scrotum. Ultrasound uses high frequency sound waves to assess the structure of the testicles, epididymis and scrotum. Doppler ultrasound is used to assess the blood flow in these tissues.
Testicular ultrasound can be requested for a number of reasons including:
- Evaluate a mass or pain in the testicle.
- Identify and monitor infection or inflammation of the testicle or epididymis.
- Identify twisting of the spermatic cord cutting off blood supply to the testicle (testicular torsion).
- Locate an undescended testicle.
- Identify fluid in the scrotum (hydrocele), fluid in the epididymis (spermatocele), blood in the scrotum (haematocele) or pus in the scrotum (pyocele).
- Evaluate an injury to the testicles/scrotum.
You will need to change for this examination. The sonographer will leave the room. In the privacy of the ultrasound room you will remove all clothes below the waste, and lie on the examination couch under the sheet provided. The sonographer on her return will raise the sheet slightly to expose the testicles. You will be asked to tuck the sheet tightly under your bottom. This holds the penis out of the scanning field.
Warm, clear gel will be applied to the skin of the scrotum. The gel enables the ultrasound to penetrate the skin layer. The sonographer will gently move the probe over the surface of the scrotum to assess this region, recording images of the tissues during the exam. On completion of the study, the sonographer will provide you with soft and absorbent wipes, leaving the room so that you can tidy and dress.
