Prerenal Azotemia Bun
Neurogenic bladder. Can bun 74 creatinine 2.5 values improve with b12? It went down to 44/1.5. Does the ratio indicate azotemia or urinary retention?
Here are some...: Pre-renal azotemia denotes elevation of BUN & creatinine resulting from decreased ability of blood flow to pass through kidneys for effective filtration caused by low blood volume for BP commonly secondary to dehydration or blood loss. If duration and degree of the mentioned conditions last and/or worsen, microscopic change in severe damage (necrosis) fine kidney filtrating tubules ensue - ATN. ...Read more
Does urine specific gravity increase or decrease in post-renal azotemia ? And what about pre renal ?
Depends : In pre renal azotemia if due dehydration or volume depletion, specific gravity should be high but depends on baseline kidney functions like any underlying kidney disease. I am not sure what you meant by post renal azotemia- in general someone passing lots of urine and is clear, specific gravity should be low as it is likely to be dilute urine; but are some exceptions. ...Read more
Blood Urea Nitrogen: It is a test which identifies the breakdown products of urea in your blood. Urea is itself a breakdown product of proteins so that the BUN is an indirect measure of protein metabolism. BUN is elevated in kidney dysfunction, fever, increased catabolism, high protein diet and intestinal bleeding. ...Read moreSee 1 more doctor answer
Kidney or load: The BUN is a measure of the amount of nitrogen in the blood in the form of urea, and it is, thereby a measurement of renal function. Thus, if one improve the renal function the BUN will go down. ...Read more
