Ultrasound is the first line of investigation in both antenatally detected abnormalities and in symptomatic
children. ● The bladder should be scanned first, as voiding may often occur during the examination.
● Measurements of both kidneys, either length or renal volume, should be taken to highlight any difference in size and to provide a baseline for further growth comparison.
● A variety of planes can be used to view the kidneys in children. Often a posterior approach is best for obtaining an accurate bipolar length.
● Ensure that renal pelvic dilatation is not physiological, by rescanning postmicturition.
● Measure the anteroposterior diameter of any renal pelvic dilatation in transverse section through the renal hilum.
● Always scan the bladder immediately after micturition, paying attention to the ureteric orifice and looking for any ureteric or renal dilatation which may suggest reflux. Measure any residual volume.
● Colour Doppler may be helpful in identifying the ureteric orifice, by locating the jets of urine entering the bladder (Fig.ULTRASOUND IMAGES BELOW).
