Hello, welcome to health care magic and thanks for the query. The results show that you are suffering from renal colic due to calcium oxalate stone. Prevention of calcium oxalate kidney stones requires making changes in fluid intake and consumption of sodium, animal protein, calcium, and oxalate. Fluid intake(water) should be 2 to 3 litres a day and it is very beneficial not only in preventng calcium oxalate stones. Thus as part of preventive measures you should; -reduce sodium (table salt) - reduce animal protein, such as meat, eggs, and fish -get enough calcium from food or taking calcium supplements with food so as to prevent absorption of oxalate and -avoiding foods high in oxalate, such as spinach, rhubarb, nuts, and wheat bran Hope this helps you Dr Achuo
