My first comment is actually most transplant surgeons are very good, and we do well to trust their judgement. I had my transplant done in Liverpool and only have the highest praise for the whole team. In y case because I was lucky enough to undergo a smaller awake operation by the same surgeon, 3 hours mind you, saw just how at home he was in the theatre as opposed to the man I knew from the visiting surgery. No surprise though, he is not a good people person but that does not matter when you are laying open on the table in an operation, his skills count then.
Anyway, do not be put off by all the warnings about what can go wrong, they are legally obliged to tell you that stuff, if someone is very unlucky something may go wrong but that is the nature of life, most operations go without hick up. Looking back there is no way I would stop the procedure under any circumstances, it is a truly life changing procedure, even with the effects of the Immune suppression med after.
Questions I asked, were in the main just curiosity, a bit about the preparation procedure, what will happen, a bit about the anaesthetic procedure, although before the op you will have a chat with them, how long the whole op will take, a bit about the recovery procedure, first few hours back in the ward, WATER INTAKE REQUIRED, although once you come out of the theatre you will have a drip feeding you at least 4 litres a day, all the pipes that once you start to gather where you actually are, the neckline etc and how and when each gets removed and how long all things being equal you will stay in hospital.
My wife donated and was out of hospital way before me, strong as an OX and has no side effects at all, bar a bit of obvious pain associated with having a kidney taken from her back. By the way your new kidney will be plonked in front, and takes a while getting used to the lump but you do.

Good luck but I'm sure you will not need it, the teams are very good.
