emacs: close buffers list on selection

Is there a configuration hook to make the "Buffers List" buffer automatically closing when a buffer is selected in such window? Each time the buffer list opens and I select a buffer I have to manually close it using C-x C-k and this is annoying, also because it leaves the frame split in at least two windows.

Try helm. It will change your Emacs experience forever. You will be able close, preview and search within buffers directly from the buffers list. If you use (helm-mode 1), helm will replace most Emacs menus with the corresponding helm equivalent. - Amelio Vazquez-Reina

Not sure about a config option, but you can always use q (or a C-x 1 in your current buffer) instead of C-x C-k to close the temp buffer.

P.S. Almost nobody uses buffer-list these days. Most Emacs users simply remap it to ibuffer (its much smarter and you might like the fact that its temp buffer disappears by default):

(global-set-key (kbd "C-x C-b") 'ibuffer)

You can tweak this function for your requirement:

(defun kill-other-buffers ()
  "Kill all other buffers."
  (interactive)
  (mapc 'kill-buffer (delq (current-buffer) (buffer-list))))

This code kills all the buffers except the current one. Source: Emacs Wiki
