Renal ultrasounds are a noninvasive medical exam that uses sound waves to produce pictures of the kidneys and bladder. It helps doctors diagnose and treat urinary conditions. It is safe and painless. You will require a full bladder for this examination.
Empty bladder 90 minutes before your appointment. Drink 1 litre of water over the next 30 minutes and HOLD.
You must finish drinking the water 1 hour before the appointment in order to have your bladder full at the time of the appointment.
Please let us know if you have a catheter as we will need you to arrive earlier to see the nurse and have the catheter clamped.
Sometimes, if the bladder is not filled enough at the time of the scan, you will be required to drink more water and allow your bladder to continue filling before we can complete the study.
