here is the word from mom.
"Grandpa Kelly is still in the hospital. He hasn't had any more vomiting, and the surgeon is not planning any imminent surgery. He was unable to pass urine when they took his catheter out, so they had to put it back in. He is currently having a cystoscopy to see what's going on with his bladder/kidneys that's causing the bleeding. They are trying him on solid food today, and if it passes through the system, then there are no more worries on that front. They still don't know what happened to cause his stomach to swell so badly, which worries me a bit, but I'm a born worrier. Grandma is doing reasonably well, but of course she is very tired. She has to walk a long way from the car to Daddy's room and back again."
It makes me feel better for some reason to share the updates with someone. I am still worried of course but grampa is tough.
