Hi I'm trying to get the vowel "u" between two other vowels.
treuas -> get the "u" because it's between "e" and "a"
louder -> dont get anything because "u" is not between two vowels
I tried this expression: (?:[aeiou])[u](?=[aeiou]) but it works partially because I get the "u" but also the vowel before the "u".

What you have (question mark, double colon) is a non-capturing subgroup.
