These pictures were taken at 6 weeks old and he's now 7 weeks. My how the time flies!!
Peter is happy to report that our first trip to the nephrologist's office went well. The two tests we had last week showed that his left kidney is still abnormally small (below the 5th percentile) and has very little function. The right kidney is growing well and functioning well. The left kidney is growing though, so, at this point, we expect that it will continue to grow throughout his life, just on it's own growth curve. It will always be small and it will probably always have some functionality to it (though not enough to take over for the other kidney if that kidney were damaged in any way).
His ultrasound showed that he has mild (grade I) hydronephrosis in the good (right) kidney. This can be normal up to age one, so we will get serial ultrasounds over the next year to watch it. If it stays the same or gets smaller, then that is great. If it worsens, then we will have to do another test (VCUG) to see if he is having backflow of urine up into his kidneys. That can cause lots of infections and damage the good kidney which is why it is necessary to watch it so closely. I'm content that it hasn't worsened in the first 6 weeks of life, so I'm not worried about the future.
Since my office is on the same floor as the nephrologist's, I was able to stop in and see all my coworkers after the apt. It was wonderful to see everyone!

We're so happy that he is doing well overall and glad that we really haven't been given anything to worry about. I'm so thankful!
