This condition of one kidney
being larger, hydronephrosis
is the most commonly diagnosed condition in the unborn baby. As long as it is on one side only, there is nothing to fear. 85 % of these will NOT require any treatment and the remaining 15% do have a solution, once the baby is born. Please confirm that the fluyid around the baby is normal in volume. You must remember that 25 years ago, these pregnancy
scans were not done and most of these babies used to be born and grew up without anyone knowing better !
It is important that the baby receives a scan soon after being born and may need further tests if the kidney is still enlarged but there are options for treatment. So please go ahead and enjoy the rest of the pregnancy
