Yes, green tea is generally considered okay, and potentially beneficial, for kidney stones due to its antioxidants and potential to lower stone-forming substances like oxalate, but moderation is key as all teas contain some oxalates; focus on adequate hydration with green tea instead of sugary drinks, and consult a doctor if you're prone to stones.
Choose a Lower-Oxalate Tea: Green, white, and herbal teas have much lower oxalate levels than black tea. These can be a much better option for people at risk of developing kidney stones.

There's evidence that tea, particularly green tea, can help protect against kidney stones.

Tea contains oxalates in varying amounts depending on the type and duration of the infusion. The amount of oxalate measured for black tea varies from 2.7 to 4.8 mg/240 mL (one cup) of tea infused for 1–5 min [2], whereas the amount of oxalate in green tea ranges from 2.08 to 34.94 mg/250 mL of tea [3].

Factors that influence stone passage include the stone's size and location. The larger a stone is, the less likely that it will pass without surgery. Surgical treatment is usually recommended for stones 0.5 centimeters in size and larger, as well as for patients who fail conservative management.
Conclusions. Consumption of sugar-sweetened soda and punch is associated with a higher risk of stone formation, whereas consumption of coffee, tea, beer, wine, and orange juice is associated with a lower risk.
