  if(is_object($result[0])) {

You could add:

$url = get_bloginfo('wpurl') . "/";
$permalink_title = str_replace($url, "", get_permalink($result[0]->ID));
return $permalink_title;

But its always best to use wordpress functions to get links. Say:

function get_laterst_post_url() {

$args = array(
'numberposts' => 1,
'orderby' => 'post_date',
'order' => 'DESC',
'post_type' => 'post',
'post_status' => 'publish',
'suppress_filters' => true );

$recent_posts = wp_get_recent_posts();

$url = get_bloginfo('wpurl') . "/";
$permalink_title = str_replace($url, "", get_permalink($recent_posts[0]["ID"]));
return $permalink_title;
}
