My wife only has one kidney and was admitted to the hospital when a 5mm stone put her in complete renal failure. A stent was placed 72 hours ago and she is still recording high BUN and creatinine levels. Today her BUN is 326, down from 330 yesterday and her creatinine is 3.2, down from 3.3. Should we expect these numbers to continue downward toward more normal levels? Is acute dialysis indicated if they do not decline? Urine output is normal with the stent in place but what happens when it is removed?
Hello and welcome to Chat Doctor. Your concern regarding acute dialysis is decided, on daily creatinine and urea levels, as well as potassium and other electrolyte levels. Symptoms of fluid accumulation levels in body, due to acute kidney failure is another dialysis indication. As your wife has one kidney, a block caused by a stone is an emergency. The block is cleared by placing a stent. Gradually, her creatinine and urea levels and potassium levels shall start reducing to normal levels. She may even pass the stone spontaneously. Pray for that. After kidney function levels are normalized, It's back to healthy life. Wishing her a speedy recovery.
