Hi, i underwent a pcnl surgery in my right kidney this year to remove kidney stones and it was successful but i want to know how can i prevent them from reforming again the stones type were calcium oxalte and uric acid ?

Ways to reduce recurrent kidney stones include: increasing fluids to 2L daily, limiting animal protein/salt, and increasing citrate. It would be best to speak with your doctor or a kidney specialist about a specific approach based on your situation. They will need to perform a 24hr urinalysis to assess what specific factors are directly contributing to your stones.

Main thing is water. Drink plenty of it. This is an unusual mix of stones. Limiting your proteins intake will also help.
