Mer, what the heck? Do they think people have transplants because they have nothing better to do??? Geez! So okay...I hope the doctor documents every little thing. Did he get labs done, too? If his creatinine and BUN are okay, I wouldn't worry too much about the kidney if they didn't notice any cysts or tumors.
Keep us updated, okay?
The Topamax might be the culprit. But his BUN is a whole lot better than mine, which was 33 as of yesterday. I'm cutting back again on Lasix and Aldactone--from 3 x a week to once a week. I know it's causing the elevated BUN in my case.
