I've always wondered what the deal was with Darth Vader's "crotch door". Does he use a catheter (due to all his injuries) or does he simply flip the door up and whip it out? I've never really seen the the back of his suit under his cape to see if there a corresponding "back door".

It doesn't look like he carries a catheter bag nor a colostomy bag in his suit or anything.

Is this addressed anywhere either in canon or legends sources?

  • You could randomly poke buttons on his chestplate to see which one causes the "crotch door" to pop up.

It gets recycled, erm, somehow. At least according to the Star Wars: Blueprints - Ultimate Collection.

Given that the technology exists to utterly vaporise stuff in the Star Wars universe, there's really no reason to assume he needs to pee/poop at all.
