Do you have details on this? The (non-new) system is (At least in the US), a piddle pack. It's a thick plastic bag that folds flat, filled with kitty litter. Turns into pee gel. That's for men. The women's ones are more complicated, and have electrical pumps.
Pretty sure astronauts do too. I remember the weird astronaut love triangle incident where some astronaut lady who was in love with some other astronaut drove nonstop cross-country with apparently a BB gun and wearing a diaper to do God knows what to the guy. It was explained that wearing a diaper during spacewalks was routine for astronauts, so it probably seemed like a reasonable and convenient thing to do for her, rather than crazy and outlandish as it seemed to most regular people.
