An ultrasound prostate uses sonography or high frequency sound waves to produce images of the prostate. This test is commonly used for evaluation of the prostate gland in men with elevated prostate specific antigen (PSA), or with abnormal urinary symptoms.
PSA is present in small quantities in the serum of men with healthy prostates but is often elevated in the presence of prostate cancer, infection or hypertrophy. Abnormal results should be followed up.
