At this moment when a user is renewing a listing in user_items they get routed to user_dashboard
header('Location: ' . osc_user_dashboard_url(osc_logged_user_id())); What is the correct route to keep them on user_items and not route them to there dashboard...
Will this do the trick? header('Location: ' . osc_user_items_url(osc_item_id()));

@mwindey
Yes your solution looks right.
Where is it located? I can update it in plugin as well.

You can find it in backoffice_manager / file republish.php starting from line 115 there is:
//Send user to homepage or payment page with flash message
if($pay_per_post == 1 && $item_id <> '') {
  osc_add_flash_ok_message( __('There is fee for republishing listing. After payment is successful, your listing will be activated. Please continue to payment process.', 'backoffice_manager'));
  header('Location: ' . osc_route_url('payment-publish', array('itemId' => $item_id)));
} else {
  if($redirect == '') {
    if(osc_is_web_user_logged_in()) {
      header('Location: ' . osc_user_dashboard_url(osc_logged_user_id()));
    } else {
      header('Location: ' . osc_base_url());
    }
  }
}

@mwindey
This is correct function, yours is wrong.
osc_user_list_items_url()

Mine was only a guess  Yours is correct and works perfectly.... Thanks

    if(osc_is_web_user_logged_in()) {
      header('Location: ' . osc_user_list_items_url());
