After an abdominal aortic aneurysm repair, which renal parameter should be monitored?

• A. BUN and creatinine and urine output
• B. ALT and AST
• C. Amylase and lipase
• D. Bilirubin and albumin

Answer: (A)

After abdominal aortic aneurysm repair, the kidneys can be sensitive to changes in blood flow during surgery, so assessing how well the kidneys are filtering and perfusing is crucial. The best indicator of renal status is BUN and creatinine together with urine output. Creatinine closely reflects glomerular filtration rate, so rising creatinine signals impaired kidney function. BUN can rise with reduced perfusion or dehydration, and urine output provides real-time information about kidney perfusion and urine production. If these values trend up or urine output falls, it points to possible acute kidney injury and prompts interventions to improve perfusion and protect the kidneys. The other parameters target liver (ALT, AST; bilirubin, albumin) or pancreas (amylase, lipase) and don’t specifically reflect renal function in this surgical context.
