My niece was born in the year of 2011,that time her right side
kidney was bigger than the usual,and found that it's not functioning, so we are doing frequently check up with the doctor every six months late every year concern doctor said it will automatically size will decrease and later it will gone completely, as per recent scan reports found that the kydney was not visualised, and found left side kydney is bigger than Last the year size, here I attached the previous scans report for your reference.
So request you please advise for further
