What is the meaning of urine BUN?

Urine BUN is the abbreviation of urea nitrogen, which is an indicator of whether the human kidney function is normal or not. If urea nitrogen is greater than 7.5 mmol/L, it indicates poor kidney function. Based on the value of urine BUN, you can assess whether the kidneys are normal. If urinary BUN is elevated, the degree of renal failure can be assessed based on the elevated value. If there is renal failure, a comprehensive judgment should be made with creatinine clearance, as well as blood potassium and sodium bicarbonate levels, before deciding how to proceed with treatment. In case of renal failure, timely treatment is necessary to prevent further aggravation of renal failure.
