You could use

Route::resource('admin/users', 'UserController');

You catch the query like

Redirect::route('admin.users.show', ['users' => 'name']);
...
public function show($username)
{

I'm the type of person who likes grouping routes.. For instance, when I design admin routes.. I usually have the following

Route::group(array('prefix' => 'admin', 'before' => 'user_is_admin'), function(){
    Route::group(array('prefix' => 'users'), function(){
        Route::get('/', array('as' => 'admin.users.index', 'uses' => 'Admin\Users@index'));
        Route::get('create', array('as' => 'admin.users.create', 'uses' => 'Admin\Users@create'));
        Route::post('/', array('as' => 'admin.users.store', 'Admin\Users@store'));

        Route::group(array('prefix' => '{id}', 'before' => 'valid_user'), function(){
            Route::get('/', array('as' => 'admin.users.show', 'uses' => 'Admin\Users@show'));
            Route::get('edit', array('as' => 'admin.users.edit', 'uses' => 'Admin\Users@edit'));
            Route::patch('/', array('as' => 'admin.users.update', 'uses' => 'Admin\Users@update'));
            Route::delete('/', array('as' => 'admin.users.destroy', 'uses' => 'Admin\Users@destroy'));
        });
    });
});

You'd need to create those two filters in this case of use
