Welcome to HCM!
I have gone through your query and you have a high reading of urea, while other kidney
function test are normal.
Usually, high urea levels are indicator of kidney disease but a lone findings needs to be evaluated further.
It would be good if you can repeat the kidney function test again, even then if you get the same results, one needs to investigate further.
So, first recheck the finding, may be from a different laboratory, and later If required, you should meet the urologist/ doctor for a thorough evaluation of urinary system
Hope the reply helps you
