No it doesn't: In fact water in tea is good for stone prevention!

Evidence is scanty: The pop idea is that iced tea is loaded with oxalate the causes stones. Some foods (famously rhubarb) have very high levels & do seem linked with stones. I searched the nih database for the past two decades and found one uncontrolled study in an obscure eastern european journal, two finding green tea drinkers have fewer kidney stones & couldn't find the hyped 2012 "loyola" study.
