What carrier do you have? Some carriers frown upon rooting the phone and some manufactures warranty will be void if rooted.
Can't say I know how to root your device, but I will say to read, read, read and understand the process of rooting.. Also read on how to recover from problems that may arise when rooting.
I did find these guides for it though:
Main: [Guide]Unlocking bootloader and rooting Xperia U wilth custom rom and Kernal
I am planning on rooting mine soon and like I said, just read and get familiar with the terms of rooting.
I would also read if there is a way to bring the phone back to stock in case of a warranty claim if you need to send it in
