Hi Tulip so glad you found us here. Wow, that is a long time for your dad to be on dialysis, he must be getting excellent care.
Not sure about the contraceptives or antidepressants. Yes to the catherter, but it is inserted after you are asleep, stays in about a day to help moniter your urine production. It is not painful for removal. Bowel prep is up to the surgeon some have you do it, some don't. But it is done at home the night before.
All of these questions can be answered by the transplant co-ordinator and you shouldn't hesitate to ask questions. Make a list so you have them ready. If there are some they can't answer, they will get back to you. I had the best co-ordinator. If the one you are assigned is less than stellar then ask to be given a different one, some are better than others, and you really need to feel comfortable with the one you have. Also a donor advocate is also important. Any time you have doubts, they are the one to speak with.
I will make a suggestion that you try to be in the best physical health you can be at the time of donation. A good healthy diet, very low sodium, lean meats, lots of leafy green and bright colored veggies, and fruit. Try to make them as fresh as possible. And low fat dairy. It will help with your healing and recovery immensly. I wish I had this info before my donation, my recovery was a bit slow because of it. I had some other surgery 6 months later, it wasn't abdominal but still involved, and what a difference after changing my diet and exercising regularly. I can't speak strongly enough about being prepared.
There is some instances of depression after this surgery as it can affect hormones in your system. There have been a couple of people that had to start on antidepressants after the surgery that never had issues previous. As long as you are aware of this on your long term health, I wish you the best.
You will have a wonderful support team here and everyone is helpful so welcome again and best wishes on your donation journey. Janice
