bandage

Q: If a male had an op and the wound is in a bandage and then he has intercourse with his wife, how will he make ghusal as he cannot remove the bandage since water cannot be put on the bandage or the wound? Will masah be made over the bandage. 

Q: I have an aunt in Australia who has forwarded the following question: She has psoriasis on her feet which at times results in cuts and a little bleeding. These are bandaged. Is it permissible to make masah on the feet/bandages for wudhu?
