Kidney and Bladder Ultrasound
A kidney and bladder ultrasound, or renal ultrasound, uses high frequency sound waves transmitted through a transducer (probe) to visualize and assess your kidneys, ureters (small muscular tubes that join the kidneys with the bladder) and urinary bladder.
Please inform the sonographer performing your exam if you have had surgery related to one of these organs, if you have a history of kidney stones or if you have stents placed in the ureters or urinary bladder.
HOW DO I PREPARE FOR MY EXAM?
- Please arrive 15 minutes prior to your appointment.
- Take all prescribed medications as directed.
- Wear comfortable clothes.
- 90 minutes prior to your appointment, empty your bladder. Then drink one litre of water within the next 30 minutes.
- If you have a problem keeping a full bladder, you may arrive early to drink your water at the clinic. If you are too uncomfortable, you may void some urine to relieve the pressure but try not to empty the bladder.
WHAT HAPPENS DURING MY EXAM?
- You may be asked to change into a gown.
- A warm, non-scented, hypo-allergenic ultrasound gel will be applied to the area being scanned.
- Your technologist (sonographer) will ask you to lower or arrange your clothing so that the area of concern is exposed to apply gel and scan the area.
- The sonographer will move the transducer (probe) around the area between your hipbones and below your belly button to take images of your kidneys and bladder.
- The sonographer will ask you to perform various breathing techniques that aid in obtaining the best images of your organs.
- You may be asked to lie on your side, sit or stand to bring your organs into a better position.
- You may experience mild to moderate pressure while the sonographer takes the images.
- You will be asked to empty your bladder at the end of the exam and then the sonographer will take more pictures of your bladder to measure the volume of remaining urine.
- The radiologist will review the images.
- It is not unusual for the sonographer to ask the radiologist to come into the scan room after your exam to speak to you about your results. You will then be free to leave.
WHEN WILL I GET MY RESULTS?
We do our best to have our radiologists interpret the information and forward the results to your doctor by the next business day.
