All the official information presented until now still presents her as "Kirishima" as far as I'm aware, so it seems she kept it that way. It's traditional in many places, but not mandatory for a wife to take her husband's name. Last I read, in Japan, a married couple can choose either spouse's name but they have to settle on one. Ghouls probably don't care as much. Kaneki and Touka both retaining their family names might be there to show it's not as much of a "thing".

Or it's just something they didn't consider much because of the circumstances and she changed it sometime during the time-skip pre-finale.
