Hey Mummato2, my DS (8) has renal problems. He was born with a congenitally absent kidney and the one he does have has many structural abnormalities and moderate VUR (an improvement on the severe reflux he had for the first few years!). I think suggesting circumcision at this stage is jumping the gun! My DS was circumcised at 12 months of age (under GA whilst a couple of other procedures were performed), we did so after multiple UTI's and pyelonephritis, despite prophylactic antibiotics from birth. I mainly wanted to let you know that US will give a very good indication of VUR. If the results of the US suggest reflux, then I would consider more invasive tests. We used to check my DS's kidney every 3 months with US and every 6 months with a MAG3, but the MAG3 was very unpleasant and really gave us little more information than the US. I refused the MAG3 from 18 months-ish (maybe 2 years??) of age unless there was an indication on US that there had been a dramatic change to my DS's renal function. What state are you in? If you are in Vic, I would very happily recommend my DS's urologist, he is fantastic.
