In brief: See below

An elevated BUN with normal creatinine and a ratio of [generally more than 18-20] occurs most commonly in dehydrated individuals and is not a sign of kidney damage.
It may also occur in in certain other conditions like bleeding in the intestines, artificial nutrition intravenously of Amino Acids and use of steroids.
