T.G.
My daughter is 15 months old and was diagnosised with grade 5 bilateral kidney reflux at the age of 10 months. She just had her 2nd 5 day hospital stay at the Children's Hospital in St. Louis, MO. Kidney reflux allows the urine to back flow into the kidneys. And yes, kidney reflux can be hereditary and 1 in 3 siblings have a chance of being born with it.
A renal untrasound will show the kidneys and any scaring that may have occured (any kidney infection can result in kidney scarring). The VCUG is a test that allows them to inject dye into the bladder and then a series of pictures allows them to watch the urine as the bladder tries to empty. If urine is backing up the test will show it. Grade 1 - 3 kidney reflux usually means the child has a good chance of out growing it. If your child gets reoccuring infections, they may use a low dose of daily antibiotics. Grade 4 is a little more severe and usually requires daily antibiotics. There is still a chance it can be outgrown. Grade 5 is the most severe and there is very little chance of it being outgrown. Antibiotics are started immediately and any fever your child gets has to be checked right away. Grade 5 usually results in surgery to correct the problem.
I would not worry yet. If the test reveals a problem you will be refered to a pedi urologist.
Educate yourself. Google Kidney Reflux in children.
If you find that she does suffer from kidney reflux and you need someone to talk to, you can always send me a private email.
