This is an examination to assess your kidneys and bladder. Other pelvic structures may be assessed during this scan such as the prostate in men.

A renal ultrasound may be asked for in the investigation of pain, kidney stones, hematuria, poor kidney function, trauma, urinary tract infections, incontinence and other changes in bladder function. To obtain images a device called a transducer is placed on your abdomen.

About this Ultrasound

Your examination will be performed by a sonographer. Upon being taken into the examination room the sonographer will introduce themselves, confirm your identity and examination. A clear gel is applied to the skin over the area to be examined. The ultrasound probe is then moved over the skin surface to study the structures below. During the study you will be asked to hold your breath and move into certain positions to allow best visualisation of your organs. Generally your bladder is assessed first and once it has been assessed you will be asked to empty it prior to the remainder of examination.

Once your examination is completed a radiologist (specialist medical doctor) will review the sonographer’s images and provide a written report for your doctor. The Radiologists may attend your examination to personally examine you and discuss your issue.

Before your Scan

A full bladder is required. Drink one litre of water finishing one hour prior to your appointment and do not empty your bladder. Distension of your bladder provides us with the opportunity to asses it with ultrasound and also allows access to assess surrounding structures. If you find that you are feeling overly full and it is causing you pain or distress, please advise reception staff on arrival and you will be instructed of your options.

Children or patients with issues of urinary retention should advise booking staff at time of appointment as your fluid intake may be varied (i.e. reduced amount required).

It is a good idea to wear clothing that allows easy access to the area that is being imaged, two piece clothing is ideal (separate upper/lower garments).
