My recent tests show BUN and creatine levels slightly above normal and potassium below normal even with supplements. Although out of normal range, I'm concerned about kidney damage due to the dyes used in angioplasty.

"Slightly" above normal could be due to a lot of factors: dehydration, diet, medications, strenuous exercise.

But I think that you are wise to be cautious with iodinated contrast media, especially with repeated exposure. Of course, it is a benefit/risk judgement with angioplasty. The need for the procedure may well be strong enough to warrant taking a small risk. These days docs can often use alternative contrast agents, use very small amounts of them, etc. (For example there is a CO2 angiogram that I had to visualize most of the system, then once the area to be treated was pinned down, they just used a miniscule amount of iodinated contrast to be sure that the stent was properly placed. No kidney damage as far as I can tell.)

Tell the vascular folks of your concerns, but it may not be possible to avoid some exposure.
