I know those words sound pretty harsh. The last time I delt with kidney issues, they told me that they don't really like using that term anymore unless you are in a serious case and using dialysis. The smaller flare ups that occur don't mean your kidneys have stopped working, so they now refer to those as something else, I don't remember exactly, but it is less dramatic sounding. They felt 'kidney failure' wasn't accurate since your kidneys CAN still work during the smaller episodes, they just have higher creatine or potassiums levels than normal. Hope that makes you feel a little better. If you're not on dialysis, then your kidneys really haven't "failed" you, they're just a little sick and need some TLC. <img src="i/expressions/face-icon-small-smile.gif" border="0">
Usually you just have to stop whatever it is that's making your levels go high. I guess they're usually related to meds.
