    This is very inefficient way but may work for You:

    Get-ADOrganizationalUnit -Filter * | Where-Object {
    @(Get-ADObject -Filter * -SearchBase $_).Count -eq 1
}

    There is no way too query for empty OU's, except to count (retrieve all children), as suggested.

    Like the others have said, there is no direct way of doing this.  But if you give it some thought you may come up with something like this which I think is more efficient: 

    

    (New-Object System.DirectoryServices.DirectorySearcher ("(objectclass=organizationunit)",@(1.1))).FindAll() | ? {
	-not (New-Object System.DirectoryServices.DirectorySearcher ($_.GetDirectoryEntry(), "(objectclass=*)", @(1.1), [System.DirectoryServices.SearchScope]::OneLevel)).FindOne()
} | Select Path
    

    

    

    The above will give you the ADsPath of all empty OUs (no children) in your domain.  However if you consider OUs that include empty OUs empty, just change the second filter from (objectclass=*) to
(&(!objectclass=organizationunit)(!objectclass=container)), and change the scope from
OneLevel to Subtree.
    

    

    
It's not considered memory efficient since it doesn't release the memory of the objects but I bet you don't have thousands of OUs so it's fine I think.
