He took them out - but left them in the room, yes. Which means that he went through all of the difficulties involved for a cannibal who wanted to feast on kidneys, including locating the organs and excising them - and then he stopped short of eating them, instead leaving them in the room as he left.
Now, even if we assume that he was full after having eaten the heart, why would he not take the kidneys along with himself as he left - they are smallish and we know that he had done so in Mitre Square - and why would he take them out in the first place if he didn´t intend to eat them?
On that note, why did he take the uterus from Chapman, if it was not for eating? Uteri are not good food, they are supposedly very tough eating. And if he found that out in the Chapman case, then why take Eddowes´ uterus?
Much as I do not exclude the possibility that he did eat an organ or two, I tend to think he did not.
Good post. I think the organs he took had special meaning for him. And I’m at about 50/50 on the canniblism.

The heart, despite all of its romantic symbolism, is still an internal organ just like the uterus and kidneys. It seems to me that if you want to assign some meaning beyond that that you would also have to do it for any organ that was taken. Why simply focus on the heart to the exclusion of the other organs?
