Question 22

22.  All of the following have been identified as causes of renal failure except:

A.  Pregnancy

B.  Cisplatin

C.  Penicillins

D.  Rhabdomyolysis

Answer and Explanation 21

21.  B is the correct answer.  The stone is on the left.  You know this is a ureter stone as opposed to phlebolith because the kidney and collecting system is dilated on that side.  CREST syndrome has calcium deposits associated with it but usually does not give these findings associated on CT scan.  Amyloidosis usually has to be made by renal biopsy.
