I just talked to Brent.  They are talking about letting him go as early as tomorrow or Monday.  His creatinine has been staying steady at 1.3 for the last three days, which is on the high end on normal.  Brent was retaining some fluid from surgery so they gave him some Lasix last night (a diuretic) and he took a lot of the fluid off.  He has been up and walking and feeling a lot more mobile.  He even went 12 hours without pain medicine last night.  Craig came up to the room again yesterday and did a lap around the hall with him.  Craig was discharged yesterday afternoon!  My kids are doing well and have had a good couple of days.  Every few days they are drawing antibodies, since Craig wasn't a perfect match, so make sure that Brent isn't creating new antibodies against Craig's kidney.  So far, they have been great, and not elevating at all.
