What Causes Strong Odour To Urine?

My urine smells strongly in the mornings, and retains this smell throughout the day though sometimes not as strongly. I had heard that urine should be odorless unless you have bacteria in it as well as when you are not hydrated. I have no pain or discomort when i urinate, nor do I have any other signs or symptoms. I do not drink as much water as I should, and do not feel thristy very often. Should I worry about this smell?
