Brief Answer:
Dear XXXX

Detailed Answer:
Hi
Mild dilatation of the renal pelvis is a relatively common finding during prenatal (i.e. during pregnancy) Usually this is insignificant and will disappear on follow up ultrasounds as the child grows.

It is usually with moderate and severe abnormalities that children suffer with repeated urinary infections and such children require surgical correction of the problem. However this is not the case in your son.

In the absence of any ballooning of the renal pelvis or of the ureter, it is unlikely that there is any obstruction. If the dilation persists, a 'diuretic renogram' will help to fairly conclusively rule out obstruction...

Warm Regards
