Most common factor in postoperative renal failure is
A. Postoperative hypovolemia
B. Use of nephritic anesthetic drugs
C. Hemolysis following massive blood transfusion
D. Associated post-renal obstruction preoperatively

ANS. A.
Postoperative hypovolemia.
There
are three categories of ARF
Pre-renal ARF 5 5%. due to renal hypoperfusion without
compromising the integrity of renal parenchyma.
Intrinsic renal ARF 40%. disease that directly involves renal
parenchyma.
Post-renal 5%. disease associated with urinary tract
obstruction.
Prerenal
ARF most common form of ARF and represents a physiologic response to mild to
moderate renal hyperperfusion.
Intrinsic
renal ARF due to ischemia is likely to occur following severe renal
hypoperfusion complicating hypovolemic or septic shock or following major
surgery.
ARF
due to hemolysis is relatively rare and is observed following massive blood
transfusion reactions.
