@cindon1977 contrast dye is definitely not good for already unhealthy kidneys. Does your nephrologist know you had a procedure using contrast dye? He/she should be made aware and new bloodwork ordered. Good chance it will improve without starting dialysis.
Good Luck!

It should go back up, but remember kidneys don't ever heal themselves completely. Mine has been up and down for 15 years now but I know it will never be back to where it was when all this started. I just wish I had known what taking 2 cat scans every 2 or 3 months was doing to me.
