kidney stoned

[KJ]

I've had two friends get kidney stones recently. After seeing the go through very acute pain, I was wondering what can be done to avoid getting them? any proven methods? (ie. not old wives tales like cranberry juice)
thanks

But cranberry juice is not an old wives' tale; it actually helps. I had a couple of kidney stones a few years ago and by Christ do they hurt! I am determined not to repeat the experience. Too much vitamin C can, I am told, encourage them. A couple of litres of pure water per day will help guard against them, as will a diet containing plenty of unprocessed food.

Sorry, I should also have mentioned that alcohol other than in moderation will cause varying degrees of dehydration, which is also a cause.

Limit intake of chocolate, cola drinks, red meats, nuts, caffiene - all the good stuff. Lots of H2O helps also.

The only time I ever had to miss a gig in my life was when I ended up in an ambulance due to a kidney stone attack.I had no clue what was happening to me so my wife called 911. $440 for just the ambulance ride. A friend of mine said "next time call a limo...it'll be cheaper." But seriously, WORST PAIN EVER ! ! ! ! ! Drink ALOT of water every day.
