"Kata" has several homonyms in Japanese but "katadori", in Aikido context, means "shoulder grab/seize". The word "Ikkajo" is originally from Daito-ryu and just means "first list", however Yoshinkan-style Aikido uses the word in place of what most other styles call "ikkyo" (meaning "first teaching"). "Ude osae" means "arm-pin", and, IIRC, it is what Tomiki (Shodokan)-style Aikido prefers to call ikkajo/ikkyo. "Ura" means "rearward" with an implied meaning of "hidden". All put together, assuming you have your terminology straight, that means you are looking ikkajo/ikkyo performed with an ura (tenkan to your own rear) movement, rather than an entering (irimi/omote) movement, with uke initiating with a shoulder grab.

Now, if you are looking for techniques involving pins using a jo, go to Youtube and search for "aikido jonage" or "aikido jodori". Once you find which one you're looking for, share the link and let us know which one it was, and maybe we can be a bit more helpful on what it might actually be called (hopefully it will be something other than "kokyunage", which is a vague label given to several vaguely-related, otherwise-unnamed techniques).
