I have pretty good knowledge of kidney failure, my Mom died of End Stage Renal Failure..we dealt with it for about 10 years.

My Mom developed it due to her diabetes, but I would imagine if your AS decided to attack your kidneys then it could do just about anything.

I dont think it is a common occurance with it but I couldnt count it out.

Speak kindly, Live simply, Care deeply, Love generously, and BLAH, HA, HA, LOUDLY! every chance you get.
