The renal ultrasound involves the assessment of the structure of the bladder, the flow of urine into the bladder from both kidneys, the volume of urine remaining in the bladder after it is emptied, the prostate in male patients, as well as both kidneys.
You will not be required to change for the renal ultrasound, but you will be asked during the examination to lower your trousers/skirt slightly, or to raise their shirt or top to the level of the chest. A clear gel will be applied to your skin during the study, this is to enable the ultrasound to penetrate the skin layer.
You will initially lie on your back at the beginning of the examination, while the bladder and flow of urine into the bladder, (and the prostate in the case of male patients) is assessed. You will then be asked to go to the toilet and totally empty your bladder. On your return, you return you will again lie on your back while the emptied bladder is examined. The sonographer will then ask you to lie on your right and then left side, so that both kidneys can be assessed. This completes the study.
