If you disputed and TU deleted, then it's gone, unless you never paid it.  The CA can rereport it, or they can sell it to another CA who can also re-report it. 

IMO, if I had the money and it was legit, I would pay it in exchange for a written agreement that it will never report again with any of the CRA's.

If I disputed it because it wasn't mine, then I'd just keep copies of my report now that it's gone and if it resurfaces, then I'd go crazy on that CA.
