Risk Factors for Complications During the Procedure

Obesity can make this examination more difficult to perform and less accurate.

What to Expect

Prior to Procedure

  • Your doctor will do a physical exam.
  • Avoid carbonated drinks, such as sodas and seltzers.
  • You must have a full bladder for the test; do not empty your bladder until after the ultrasound.

Anesthesia

None

Description of the Procedure

This procedure can be done at a doctor's office or hospital. You lie on a table and the doctor applies a sound-conducting jelly on your abdomen over your bladder and kidneys.

The ultrasound machine has a hand-held instrument called a transducer, which looks like a microphone or wand. The transducer is passed over the skin where the jelly was applied. The transducer sends sound waves into the body. The waves bounce off the internal organs and echo back to the transducer. The echoes are converted to images that are shown on a screen. The doctor examines the images on the screen. He may make a photograph for further assessment.

After Procedure

A radiologist examines the ultrasound image for abnormal masses or blockages.

How Long Will It Take?

30-45 minutes

Will It Hurt?

No

Possible Complications

None

Average Hospital Stay

None

Postoperative Care

None

Outcome

If the doctor or radiologist detects an abnormal mass or obstruction, additional tests will be done to determine the exact problem and cause.
