Probably high blood pressure for 15+ years, but at the point where this was discovered it was impossible to know for sure if it was the primary reason or a consequence of kidney failure. Fortunately, the blood pressure turned out to be easy to manage with medication.

And after the transplant, things have gone exceptionally well and I live a completely normal lifet. I just need to down a fistful of pills every day :-)

Holy crap, that sounds exactly like mine. We dont know the reason why I had kidney failure and there was so much damage a bioposy would not be fruitful. The guess is blood pressure, but its not known.

Nephroschlerosis?

If the experience taught me anything: make sure you start doing an annual health checkup with bloodwork every year or two starting in your 20s. It is likely I could have avoided this.

I dont know the term, but by the time we found out there was so much bruising on the kidney, couldnt do a biopsy as it would cause bleeding and further delay the transplant. I didnt want any more delays so I opted out of it after discussing with my doctor.
