my daughter has hydronephrosis, so she's has to go through all sorts of things including vcugs. basically, before her birth they saw that one of her kidneys was enlarged, so they check her regularly. in infants utis can be especially dangerous if not caught immediately, so that's why they take them a lot more serious than they do for adults. if there is reflux, it wont necessarily go away on its own, and sometimes surgery is necessary if things get worse. they will probably watch it until your son is a year or so, at least thats what theyre doing with my daughter. i think its better to be safe than sorry with this sort of thing. utis that early arent really typical, so it's good that theyre keeping an eye on it. let me know if theres anything else you want to know about our experience. my daughter is 9 months old. good luck!
