Description

BUN/Creatinine ratio differentiate between acute and chronic renal disease.

Prerenal azotemia appears when there is poor renal perfusion like hypovolemia, hypotension.

Postrenal azotemia is due to obstruction.



Prerenal acute failure = BUN/Creatinine ratio  > 20 : 1

Renal acute failure  = BUN/Creatinine ratio < 20 : 1

Suggest renal azotemia or late postrenal azotemia when  BUN / Creatinine ratio = < 10:1
