1. Mr. Jeffers was admitted 2 days ago for a carotid endarterectomy. A Foley catheter
wasinsertedintraoperatively and remainsin place. His urine output has declined markedly
despite continued IV fluidinfusion. Today his morning labs reveal a BUN of 19 mg/dL and a
creatinine of 2 mg/dL. A leading differential includes:
A. Foley lodged in the urethra causing post-renal failure
B. Decreased renal perfusion causing prerenal failure
C. Age-related decreased eGFR causing prerenal failure
D. Post-surgicalrhabdomyolysis causing intrarenal failure
Answer:
• D. Post-surgical rhabdomyolysis causing intrarenal failure
During surgery, muscles and injured. This can result into rhabdomyolysis, which isthe
breakdown ofmuscles to release proteins. The excess proteins causes an increased level of
creatinine.
Mr. Jeffers is from surgery (post-surgical) and his creatinine levels are above normal. The
normal creatinine levelsrange from 0.6mg/dl to 1.2mg/dl. Thus, the most likely differential
is: Post-surgicalrhabdomyolysis causing intrarenal failure.
