How painful is a prostate ultrasound?
It is safe and painless. It produces pictures of the inside of the body using sound waves. Ultrasound imaging is also called sonography. It uses a small probe called a transducer and gel placed directly on the skin.

How is ultrasound of prostate performed?
Prostate ultrasound uses a probe about the size of a finger that's inserted a short distance into your rectum. This probe creates harmless sound waves.

If the bladder is not well filled the patient should be given fluid to drink and, if necessary, a tablet of Furosemide in order to accelerate the diuresis.
Why do you need a full bladder for prostate ultrasound?
When sound waves move through the body, they “hit” different mediums, such as fluid and air, differently. A full bladder creates a reservoir of fluid that enhances the movement of sound waves through the abdominal cavity. This creates a clearer view of the structures that need to be observed.
Are you awake for a transrectal ultrasound?

What is Ultrasound Imaging of the Prostate?
Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. It is safe and painless. It produces pictures of the inside of the body using sound waves. Ultrasound imaging is also called sonography. It uses a small probe called a transducer and gel placed directly on the skin. High-frequency sound waves travel from the probe through the gel into the body. The probe collects the sounds that bounce back. A computer uses those sound waves to create an image. Ultrasound exams do not use radiation ( x-rays ). Because ultrasound captures images in real-time, it can show the structure and movement of the body's internal organs. The images can also show blood flowing through blood vessels.

What are the limitations of Prostate Ultrasound Imaging?
Men who have had the tail end of their bowel (rectum) removed during prior surgery are not good candidates for ultrasound of the prostate gland because this type of ultrasound typically requires placing a probe into the rectum. However, the radiologist may attempt to examine the prostate gland by placing a regular ultrasound imaging probe on the perineal skin of the patient, between the legs and behind the scrotum of the patient. Sometimes the gland can be examined by ultrasound this way, but the images may not be as detailed as with the transrectal probe. An MRI of the pelvis may be obtained as an alternative imaging test, because it may be obtained with an external (phased array) receiver coil.
How does the procedure work?
Ultrasound imaging uses the same principles as the sonar that bats, ships, and fishermen use. When a sound wave strikes an object, it bounces back or echoes. By measuring these echo waves, it is possible to determine how far away the object is as well as its size, shape, and consistency. This includes whether the object is solid or filled with fluid.
Who interprets the results and how do I get them?
A radiologist, a doctor trained to supervise and interpret radiology exams, will analyze the images. The radiologist will send a signed report to the doctor who requested the exam. Your doctor will then share the results with you. In some cases, the radiologist may discuss results with you after the exam.

What happens when sound waves echo off an object?
When sound waves echo off of an object, they change slightly. The ultrasound machine can interpret these very tiny changes in the character of the returning sound wave to make determinations about the object (such as the prostate) that it has hit. Different types of structures reflect or “echo” sound waves differently.
What is a prostate ultrasound?
Some scenarios that may call for a prostate ultrasound could include: 1 A man may have a PSA test done.

When a man has an elevated PSA level, then a prostate ultrasound might be used to see if there is an abnormal growth in the prostate gland. The ultrasound can help to reduce the risk of an unnecessary biopsy. 2 When something unusual is felt during a digital rectal examination, an ultrasound test may also be needed. This examination is performed during a routine health exam. A routine prostate cancer screening also includes a digital rectal exam. The nodule may be a sign of benign prostatic hyperplasia. It could also be a sign of something else, such as prostate cancer cells. 3 Men with difficulty urinating may also require a prostate ultrasound. Urinary symptoms are often a sign of an enlarged prostate. In some cases, these symptoms may also be linked to other conditions that affect the prostate.
