How to find folders

I'm looking for a way to find and remove every folder which contains files with extension .drt in it.

It's a networkshare and structure is shown below, in this case I want to delete subfolder 1 and 3

\networkshare
  \profiles
    \001
    \002
    \003
      \folder1
        \subfolder1
          \*.drt
      \folder2
        \subfolder2
      \folder3
        \subfolder3
          \*.drt
