Okay ... everyone agrees ... Chuck is doing much better! The plan for now is to continue watching and waiting. Once the kidney thing is fully resolved (who knows when??), we'll head back to Baylor Specialty. His creatinine and BUN (Blood Urea Nitrogen) numbers will need to be normal for a while. The numbers have been high ... but are slowly improving. Here's some info. I copied from the internet:

Hospitals and doctors routinely measure blood creatinine levels to determine kidney function. Creatine is broken down to creatinine, which is eliminated through the kidneys. High creatinine serum levels are thus an indication of renal failure.

The blood urea nitrogen (BUN) test is a measure of the amount of nitrogen in the blood that comes from urea. Urea is a substance secreted by the liver, and removed from the blood by the kidneys. (His nurse told me ... it is an indication of how much "junk" is being carried in Chuck's blood.)

This has been a frustrating speed bump ... now it's onward and upward!
