If you're using a nephrotoxic injectable to treat the RI, soaks can help. Most vets will recommend it at the time they set you up with your meds.
Other than that, pretty much all that has been said above, I'd agree with. Just do the best you can, and deal with it quickly if it happens. I've never had one pop up in my collection, but have unfortunately been sent snakes that were drooling straight out of the shipping bag. /headdesk
