Bladder Ultrasound

Bladder Ultrasound is an exam that obtains multiple longitudinal and transverse images of the bladder by using sound waves. A hand-held transducer (probe) is used to create images of the
bladder. It can assist in diagnosing problems, such as inflammatory process, obstruction and bladder masses both benign and malignant.


  • You will lie on an exam table with your pelvis 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 pelvis to obtain images of your bladder.


  • Forty ounces of water must be consumed one hour prior to exam time.
  • Children 12 years and under should drink only 20 ounces of water within one hour before exam time.
  • 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.


  • Let the technologist know:
    • If you have difficulty holding your bladder.
    • If you have had pelvic surgery.
    • If you take any medications.
