Hi Paulo - just a bit of confusion - it seems from your post that you have already agreed to have surgery with adjuvant RT so the salvage RT thing is not relevant to you.
How to prepare? Go shopping! The following might be useful:-
- a bucket to stand your night bag in
- a waterproof sheet or waterproof pads for when the catheter comes out
- pants (not boxers) one size larger than usual - your penis and testicles may be very swollen and will need support
- tracksuit bottoms / joggers in a dark colour with a drawstring or elastic waist - M&S do some in sweatshirt material which are easy to wash and tumble-dryable (a bonus)
Ask whether your hospital provides incontinence pads when the catheter is removed; if not, Tena for Men seem to be the most comfortable brand and are often on 'buy one, get one free' at the big supermarkets.
You could also ask whether they will provide you with a local anaesthetic gel for the eye of your penis while the catheter is in. If not, you can purchase a gel from your local chemist.
