Hi Robert,
If the gentleman is under the care of a local authority, he should have a care plan. Therefore, it might be worthwhile speaking to his carers, or the Council direct to have his needs reassessed.
re. PCA related issues, a clearer idea will form once his blood / urine sample tests are known. Again I would let his carers / the authority know that these tests are going ahead (they may do already) as he may need support if called for a follow up consultation with the prostate team / oncologist.
The bedwetting / soiling may not be prostate related so getting the right level and kind of support in place is important.

ps. look after yourself too!
