How to prepare for an Ultrasound

Ultrasound Abdomen / HBS

  • Do not eat or drink 4 hours prior to your exam. If required, plain water is allowed.
  • If you are on anti-diabetic medication, do not take the medication on the morning of your exam. You can resume medication after your exam has completed.
  • If you are on any other prescribed medication, continue your medication as prescribed by your doctor.

Ultrasound Kidneys and Bladder / Pelvis

You are required to drink water at the following interval:

  • 1st drink (200 ml) : 1 hour before the appointment time
  • 2nd drink (200 ml) : 30 minutes before the appointment time
  • 3rd drink (200 ml) : 10 minutes before the appointment time

If you have a urinary catheter, please ensure that the catheter is clamped.

Please do not go to the toilet or empty your bladder before the scan. We need to perform the scan when your bladder is full.

What happens after the Ultrasound exam

There is typically no special care required following an ultrasound.

For specialised procedures, such as Contrast-enhanced Ultrasound and Penile Doppler Ultrasound, post-procedural instructions will be given by the Radiographer/Radiologist on the day of exam.

The radiology report will be ready for your doctor to review on the day of your clinic appointment.​
