Have you had any power steering problems? Do you have reason to distrust the mechanic who gave you this diagnoses? If so, take it to another mechanic to get a second opinion.
As for the hoses, there'll be two hoses in you power steering system. One is the feed line (High pressure) to your rack and pinion, the other is a return line (Low pressure) back to the pump.
You could have a tear/puncture in the rubber, or a leak in the terminal (what connects it to the pump and rack). And finally, the pump and rack & pinion themselves can have a leak in one of their many seals.
Usually, a leak is pretty easy to find, so long as you get under the hood or the vehicle to have a look.
As for "Power steering flush", the only reason to do that is if there's debris in the system. Such as a pump has failed or the racks gears have stripped. Then that will usually place small metal particles in the fluid. And when you're replacing an old rack or pump with a new one, you don't want it to circulate that old contaminated fluid or the new ones will fail also. So then it's necessary to flush the fluid.
