Is wet food bad in any way for male cats?

I have a 10 month old male domestic short-hair. I have had him every since he was about 4 weeks old (Me and my roommate discovered him outside alone, he was abandoned by his stray mother). For about half his life, he would only eat wet cat food, he would go hungry before tasting the dry stuff. One day my mom bought him "The Goodlife Recipe" and he actually loved it! I no longer had to mix his wet food with his dry food to get him to eat the stuff. Now I'm at a dilemma. My kitten's current diet is 2 pouches of wet cad food, one in the morning, one at night, while he also has a bowl of dry food out at all times for "grazing" in between meals. Some one told me the other day that wet cat food can cause kidney stones in male cats because males' urethea has a funnel effect. I reseached this and my research tells me that DRY FOOD actually does this to cats. My roommate tells me wet food is bad because its harder to digest, but i know dry food can't be goos for cats either, just from common sense! So can anyone set me straight here? I really want to keep my cat on a regular diet of wet food because my sense tells me thats what is best for him. Should i have any worries?
