Renal Ultrasound

Renal Ultrasound is an exam that obtains images of the kidneys and bladder by using sound waves. A hand-held transducer (probe) is used to create images of the kidneys and bladder. It can assist in diagnosing problems, such as renal and bladder disease.

Preparation

• Adults drink 16 oz. of fluid one hour before exam.
• Children that are potty-trained and/or 4 years old and above drink 8-16 oz. of fluid one hour before exam.
• Do not empty your bladder until exam is complete.
• Arrive 15 minutes prior to your scheduled appointment with a prescription if your doctor has given one to you.

Procedure

• You will lie on an exam table with your abdomen exposed.
• A non-greasy gel will be applied to your skin during the exam.
• The sonographer will use a hand-held transducer (probe) against your abdomen to obtain images of the kidneys and bladder.
• The sonographer may ask you to hold your breath for a few seconds during the exam.
• You may be asked to change positions during the exam.

Considerations

• Let the technologist know:
  • If you have had any previous surgery.
  • If you take any medication.
