My child is one and half years old having hydro nephrosis (left kidney) and her right kidney is normal. I have taken MCU test in that it is normal but in scans her kidney is having swelling. We have consulted a child specialist he said no need to worry until she get any fever or pain and let us wait and see. And my daughter is fine she has frequently urination and what shall we do next either I can wait or I can consult any other doctor.
