"2.low urine sodium < 10 ( because kidney saves sodium and water,hence low urine sodium and increase urine osmolarity)"

I thought that in a case like CAH due to 21 alphaOHase deficiency there was a salt wasting dehydration that led to prerenal azotemia. Would this result not result in excess natriuresis?

Outside of the US I am not sure this would be recognised. I am a UK doctor and it is certainly not a term we use where renal failure will suffice. Should this article be merged onto renal failure to be more international in scope ad prevent unnecessary repition?Arfgab (talk) 21:38, 10 March 2010 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2010-03-10T21:38:00.000Z","author":"Arfgab","type":"comment","level":1,"id":"c-Arfgab-2010-03-10T21:38:00.000Z-Renal_failure","replies":[]}}-->
We should probably replace most instances of the acronym BUN with 'urea'. It isn't really the nitrogen that is being reabsorbed, it is the actual urea. BUN is a term best used in the context of the clinical assay, and not in the context of actual biological processes. — Preceding unsigned comment added by Jaredroach (talk • contribs) 20:14, 23 July 2019 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2019-07-23T20:14:00.000Z","author":"Jaredroach","type":"comment","level":1,"id":"c-Jaredroach-2019-07-23T20:14:00.000Z-Renal_failure_2","replies":[]}}-->
