Thank you for using healthcare magic

Your question does not indicate what his pre-existing kidney function was and I am making the presumption that the dye used was an Iodinated radiocontrast such as used for a heart catheterization or CAT scan and not a nuclear isotope or MRI contrast.

There are a few things which can be done prior to the procedure to augment some of the potential kidney toxicity however once this has occurred, there is not much that can be done other than the following:

-Avoid potentially kidney toxic medications including over-the-counter medications such as ibuprofen or naproxen
-Avoid changes in volume status such as with diuretics
-Avoid overaggressive drop in blood pressure such as with antihypertensives

If the contrast exposure was without vascular manipulation such as a catheter/guidewire as would be used in a cardiac procedure, majority of the time renal function will recover to pre-existing baseline. If this is your situation then at this point he would have to wait and see where things stand about a month from now.

If contrast exposure included a catheter or guidewire, there is the added risk of atheroembolic renal insult (small debris from the wall of the blood vessel dislodged by the wire injuring the kidney). Renal function recovery may or may not ensue. Again re-evaluation is required in about a month's time

Take care and be well
