So sorry to hear that Percy isn't well, UTI's can be quite stubborn & take time to clear up especially in older hams so she'll probably need to be on the antibiotics for longer, if you've finished the current course then I would take her back to the vet.
It is worrying but they can recover from this if it is just a UTI.
If she does end up being on antibiotics for a while longer it would be a good idea to give her some probiotics too, you can get them in P@H or other pet shops.
