Shopping trip time then Trish? Have you got all of the following in store?
Jogging / lounge pants / pyjama bottoms - preferably with drawstring waist in a dark colour
Pants (not boxers) in a size larger than usual
Waterproof sheet or waterproof pads
Books, puzzles, ipod etc
When you see the nurse, ask whether they will provide local anaesthetic gel for the eye of his penis while catheter is in situ - if not, check whether KY jelly will be okay with whichever brand of catheter tube they use. Also, will they be providing incontinence pads when catheter is removed or do you need to be referred to district nursing or do you have to buy your own? If buying, try Tena for Men which are softer than the Boots own brand ones and are often on offer at Morrisons, Tesco, etc.
