I think his short lifespan played a part in his decision to consent to Kanou's surgery. Whether it will ultimately lengthen his lifespan is still to be seen, though, and I doubt it was the sole reason for it.

Furuta is unpredictable, has done little of note (aside from taking out Eto, which just happened so Kanou doesn't know about it yet), and has yet to manifest anything beyond a kagune. Yasuhisa required a weird melding to reach half-kakuja level, has done little of note (still), and is generally somewhat insane. Kaneki, on the other hand, was never expected to survive, was dumped on the streets to die a slow, starving death, and managed not only to survive but to thrive, developed a near-complete kakuja, took out multiple high-level ghouls (starting with Yamori and the Ghoul Restaraunt), and survived being stabbed in the head.

Kanou's motivation is to "destroy the twisted birdcage." Few of his creations have shown the potential to shake anything up, let alone the world. Only Kaneki has demonstrated the ability to influence others (Amon) and the fortitude to destroy what can't be changed (the Restaraunt). Furuta, for all of his deceptions, is in it for himself and nothing else. He doesn't care about the birdcage or others, his end goal is not to bring humans and ghouls to peace, and, to be perfectly honest, he's a dangerous tool. Useful, but entirely willing and capable of biting the hand that feeds him.

No matter how you look at it, Kaneki is Kanou's masterpiece.
