I don't think there is any effective way you could easily remove uranium from the body of somebody without causing skeletal problems, because you have to mobilize the skeleton in order to release the uranium.
There are ways of removing it from the lungs, because you can remove particles. If people have cystic fibrosis, they do something they call lung lavage, whereby basically they pass saline down into the lung and wash the lungs out. You can actually do that; if somebody had a huge dose of particulate radioactive material, this is one of the things they would do, and you can wash the activity out. But you would never do that for depleted uranium exposure.
