JJcop,
Always nice to see people who are considering becoming a living kidney donor. Best advice I can give is to educate yourself on the process, ask questions and make sure you understand everything involved in undergoing an elective surgery. If you are currently a smoker, good time to stop, begin a good exercise program (nothing crazy just get moving) healthy eating etc.
Make sure you have a good support system to get you through the surgery. Look over your finances and make sure you are able to dedicate a good amount of time to take off from work for recovery and a cushion should you sustain some unanticipated side effects and need to take off more than the transplant center recommends. Make sure life insurance is in order, access to your own health insurance for future follow after the transplant center puts you back to your own doctor. You may want to discuss this with your own physician or see a nephrologist outside the transplant center to see if they would consider you a good candidate.
Be prepared to have lots of waiting. Use this time to read about the surgery, possible adverse effects.Some of the male donors on this site have reported issues regarding testicular swelling and pain as this has occurred with left donor nephrectomy.
You can even look for a buddy on this group or ask your transplant center to connect you with other donors, both who have had positive and negative experiences.
Best of luck and keep us posted.
