Hydronephrosis Update

Yesterday was our big Doctor Day to check up on little B's kidneys. Bennett woke up at 6:30, I fed him, changed him, and got in the car to head to his first appointment at Mobile Infirmary (where he was born) for an ultrasound. (ooo and I grabbed an Egg McMuffin on the way - a little treat I would love to get on my early mornings to Montgomery back in the day)
Bennett did very well at his ultrasound...talking and cooing the whole time. The same nurse who gave him the ultrasound at one day old administered this one as well - and she remembered him! Crazy. I got to see his kidney's and full tummy and full bladder. They also checked his aorta...dont know why, I think its routine.
I then took the print-outs of the Ultrasound across town to Bennett's urologist. We had a little bit of lag time, so I parked the car at the far end of the parking lot and Bennett ate his mid morning snack.
The urologist looked at his ultrasounds and told us that it hadn't gotten any worse, but it hadn't gotten any better either. I was sad bc I just knew it was gone...we had no symptoms of anything - no fever, UTI's, looks of pain or discomfort, etc. Dr Terry said this is typical - you don't have any symptoms with hydronephrosis. Bennett's right kidney is fine - no fluid. His left kidney has a little bit of fluid retention, which looks like just a dark void on the ultrasound. Both of his kidney's are still growing at the correct rate, which is a good thing. So far, Dr Terry doesn't see anything that worries him with this case. It may just be the way Bennett's kidney functions. Or it may not.
If the latter is the case, we will have to do some tests to determine what exactly is causing the fluid retention. It could be reflux from his bladder, or a blockage, or a number of other things. If it is blockage, or a small ureter, he will have to have surgery.
We have another follow up appointment in October, for a repeat of today's appointments. I am just praying by that time this will all be gone away. It's scary to think of all that could be, that Bennett may be experiencing kidney scarring that could lead to kidney failure as an adult, or even at this young of an age. We are glad we caught it early, and it may not be a big deal, but we have to keep checking to make sure.
It's hard to ask for prayers, but I think this is something we could use all your help on. Please pray that this fluid retention decreases, or goes away (!) as Bennett gets older. If this is not the case, I just pray it is nothing serious and that this is just Bennett's make up and just the way his kidney functions.
