prostate ultrasound explained

Overview

A prostate ultrasound is a safe, painless imaging test that uses sound waves to create pictures of the prostate gland. It helps your doctor see the size, shape, and texture of the prostate, and check for any unusual areas.

Yes, prostate ultrasound is a common procedure used to help diagnose prostate problems, especially in men over 50.

The test is only done on men, most often those who have symptoms like trouble urinating, a high PSA level, or a lump felt during a digital rectal exam.

Symptoms

Common symptoms

• Difficulty starting or stopping urination
• Frequent need to urinate, especially at night
• Weak urine stream or feeling that the bladder is not empty
• Pain or burning during urination
• Blood in the urine or semen

Symptoms in children

• Boys with recurrent urinary tract infections or signs of a blockage in the urinary tract might need this test, but it is rare.

Symptoms in older adults

• Same symptoms as in other men, but more likely due to an enlarged prostate (benign prostatic hyperplasia) or prostate concerns.

Causes

Main causes

• Doctors usually recommend a prostate ultrasound to investigate symptoms that suggest a prostate problem, such as trouble urinating or a high PSA level.
• It is also used to check the prostate after a suspicious digital rectal exam.
• It can help guide a biopsy if prostate cancer is suspected.

Risk factors

• Age over 50
• Family history of prostate cancer
• Having elevated PSA levels
• Having urinary symptoms that do not improve with simple treatments

When to see a doctor

See a doctor urgently if:

• If you cannot pass urine at all.
• If you see blood in your urine or semen and it does not go away.
• If you have severe pain in your lower back, pelvis, or during urination.

Book a routine appointment if:

• Talk to your doctor if you have ongoing changes in urination, such as trouble starting or stopping, a weak stream, or needing to go often.
• If you are over 50 and have not had a prostate check recently, ask your doctor if a prostate ultrasound might be right for you.

Diagnosis

A prostate ultrasound is usually done by a specially trained doctor or sonographer. You may first have a digital rectal exam (DRE) to feel the prostate. Then the ultrasound probe is placed either on your lower belly or gently inserted into the rectum to get detailed images.

Tests that may be done

• Transrectal ultrasound (TRUS) – the most common type for the prostate.
• Abdominal ultrasound – used less often, usually to check bladder volume after urination.

What to expect at your appointment

You will lie on your side or back. The doctor will apply a lubricated probe. You may feel slight pressure, but it should not be painful. The test takes about 20 minutes. You can go home right after and return to normal activities.

Treatment

Prostate ultrasound is a diagnostic test, not a treatment. If the ultrasound finds a problem, your doctor will discuss the next steps, which may include monitoring, medication, or procedures depending on the condition.

Self-care at home

• After the test, you can return to your usual activities. You may have a little spotting if a biopsy was done, but that usually stops quickly.
• Drink plenty of water to help flush your system if you had a biopsy.

Medical treatments

If the ultrasound shows an enlarged prostate, your doctor might recommend lifestyle changes or medicines that relax the prostate or shrink it. If cancer is found, treatment may involve active surveillance, radiation therapy, hormone therapy, or surgery. All treatments are tailored to your specific situation. Talk to your doctor about which option is best for you.

When is surgery considered?

Surgery is sometimes needed for very enlarged prostates that do not respond to medicine, or to remove cancer. Your doctor will explain the risks and benefits of any surgery.

Living with this condition

After a prostate ultrasound, you can quickly get back to your normal routine. If you had a biopsy, you may see a little blood in your urine or semen for a few days. This is normal.

Lifestyle tips

• Stay active and maintain a healthy weight.
• Limit caffeine and alcohol, which can irritate the bladder.
• Practice good toilet habits – don’t hold urine for too long.

Diet and exercise

A diet rich in fruits, vegetables, and whole grains supports prostate health. Some studies suggest that foods like tomatoes and fatty fish may be beneficial. Regular exercise helps with urinary symptoms and overall well-being.

Mental health and emotional wellbeing

Waiting for test results or worrying about prostate problems can cause anxiety. It’s normal to feel stressed. Talk to your doctor or a counselor if you need support.

Prevention

There is no proven way to prevent all prostate problems, but a healthy lifestyle may lower your risk of prostate issues.

Screening programmes

Some men choose to have regular PSA blood tests and digital rectal exams. Talk to your doctor about whether screening is right for you, especially if you have risk factors like family history.

Complications

If left untreated

• An enlarged prostate can lead to bladder stones, kidney damage, or frequent infections.
• Prostate cancer that is not treated may spread, but many prostate cancers grow slowly and are not life-threatening.

Long-term outlook

Most prostate problems are treatable. Detecting them early with tests like ultrasound can lead to better outcomes. For cancer, even when it is found, many men respond well to treatment and live full lives.
