About this procedure
Scrotal ultrasound examines the testes, epididymides and surrounding tissues without an incision. It may help investigate a lump, swelling, previous injury or non-acute discomfort, but an emergency must not be delayed for routine imaging.
What this topic means
A lump may be fluid-filled or solid, while swelling can arise from several distinct conditions. Ultrasound provides structural information and sometimes Doppler blood-flow assessment; final interpretation requires clinical examination.
When to seek medical advice
Arrange assessment for a persistent testicular lump, asymmetry, heaviness or gradually developing pain. Sudden severe unilateral testicular pain, especially with nausea or vomiting, is a potential torsion emergency and should not enter a routine booking queue.
Options and limitations
A scan can help identify signs compatible with hydrocele, varicocele, cysts or inflammatory changes, but images alone do not settle the cause. Normal or equivocal Doppler flow cannot by itself safely rule out testicular torsion.
Assessment and preparation
Ultrasound gel is used on the skin and the structures are imaged, sometimes with Doppler. No special preparation is usually needed. The clinician considers age, the onset of pain, examination and any prior results, and may request urology review.
Treatment, risks and follow-up
Scrotal ultrasound is diagnostic and not a treatment. A confirmed condition may require observation, medication or a different intervention. Do not massage or warm a suddenly painful testicle while waiting for a planned scan.
When urgent help is needed
Sudden intense testicular pain, rapidly increasing swelling, nausea or vomiting accompanying pain can indicate torsion. Go to an emergency department immediately or call 103/112; a planned ultrasound must not delay urgent surgical assessment.

Frequently asked questions
Is special preparation required for scrotal ultrasound?
Usually not. Follow local instructions and bring earlier scan or specialist reports if available.
Can ultrasound explain every scrotal lump?
No. Imaging is interpreted with an examination, and further tests or specialist assessment may be necessary.
Can sudden testicular pain wait for an appointment?
No. Testicular torsion is time-sensitive and requires immediate emergency evaluation, even if an ultrasound slot is unavailable.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
