My personal story:
<br>I had my kidney TX almost 4 months AFTER my double lung TX. But, my doctors already knew even BEFORE my lung TX that I was in need of a kidney also. Pre-TX I had kidney failure from long term antibiotic use and post-TX the prograf (immunosuppressant drug) caused even more damage. My doc's didn't want my lung TX and kidney TX performed at the same time (I don't remember why. I think because the surgery would take much too longer & riskier) ...To answer your question, personally in my opinion, some of it depends on your existing conditions before TX. I believe after TX it's fate. Some things aren't predictable. I'm sure it was an easier process for me because my mom was a match so that made everything much quicker. I don't question what would have happened had she not been a match. Though, Like Lex said...medications, high blood sugar and high blood pressure can also affect kidneys. The odds of survival I would think depend on all of these things. If their managed well, then there shouldn't be a lot of problems. I'm post-TX 4 years now and doing well. My Kidney function isn't the greatest but it's decent and I'm still alive and happy. That's all that matters to me.
