QUESTION 1
1. Mr. Jeffers was admitted 2 days ago for a carotid endarterectomy. A Foley
catheter was inserted intraoperatively and remains in place. His urine output has
declined markedly despite continued IV fluid infusion. 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-surgical rhabdomyolysis causing intrarenal failure
Answer:
D. Post-surgical rhabdomyolysis causing intrarenal failure
During surgery, muscles and injured. This can result into rhabdomyolysis, which is
the breakdown of muscles 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 levels range from 0.6mg/dl to 1.2mg/dl. Thus, the
most likely differential is: Post-surgical rhabdomyolysis causing intrarenal
failure.
