You're a white, man after age 20 doesn't help either. Certain meds may make you retain calcium. Water however the best preventative medicine, keep the stream clean.
Yeah, you might be right and the studies might be right too, but I don't think it's worth taking the chance. I've only gotten one kidney stone in my life, and it was while I was taking creatine. Never got one before that and haven't gotten one since. Coincidence? Maybe. But I don't think the benefit of creatine is worth the risk of another kidney stone. That kidney stone was damn painful.
Having said that, I don't think I was drinking enough water while I was on creatine and I was drinking way too much caffeine at the time - so it was partially my own fault.
