JS

function CargarPaises () {
  

elegido=$("#pais").val();
$.post("Panel_Admin/Traer_Paises", { elegido: elegido }, function(data){
$("#ciudad").html(data);
      
}); 

Controller

public function Traer_Paises($id_region)
      {
$paises=$this->Admin_Model->Traer_Paises($id_region);

POSTed values aren’t automatically passed to a method like url parameters, so your Traer_Paises() method isn’t receiving $id_region.  You need to grab that from $this->input->post(‘elegido’), since that’s how you are sending your data in your ajax call…

I think in the JS

//pais is a select html
var elegido=$("#pais option:selected").val();
//and then, de post send de option selectec value =D 

in the controller

//you must load library 'input'
$local_var_sel = $this->input->post('elegido');

public function Traer_Paises()
{
   $id_region = $this->input->post('elegido');
   $paises=$this->Admin_Model->Traer_Paises($id_region);
   $options = '';
   foreach ($paises as $key=>$pais) 
   {
     $options.="<option value=$key>$pais->pais</option>";
   }  
   echo $options;
} 

Hope this will help you. If you still face problem make sure your Database is returning value.
