Generally speaking, a prey model or whole prey raw diet, done correctly, acidifies the urine to a normal level and hence, helps prevent UTIs. Not necessarily a cure-all, however.
The main points: 80-85% meat, fed whole in mouse-sized pieces; 5-10% bone, fed with meat of course; 10% organ, half of which should be liver. This is fed over time, not necessarily perfect %s every day.
My additional recommendations: As much variety as you can manage -- cornish game hen is good small bone for cats, but also consider mice/rats, quail, duck, etc. As for meatymeat, there's beef and chicken, but also venison, pork, duck, quail, etc.
AVOID FISH. This is true for all cats - even when I get some for free I only feed fish to the cats one meal a week. But for cats prone to UTIs you want to avoid fish entirely.
