Kidney stones, also known as a renal calculus. There are many types of kidney stone according to its components and it is often classified into four major categories---calcium stone, infectious stone, uric acid stone and cystine calculi. Among them, calcium-oxalate stones are the commonly seen in clinic. If you have a high risk for kidney stones, your doctor may advise you to avoid or at least limit intake of foods that contains high amount of oxalate.
Unfortunately, spinach is a great source of oxalate, which are naturally-occurring substances found in the food you eat and in your body. Oxalate found in urine combines with calcium to form calcium-oxalate kidney stones. Too much intake of spinach can disturb the absorption of calcium and iron and under some conditions can cause formation of oxalic acid stones in the urinary tract. However this effect is not only caused by spinach, but also the intake of other high oxalic acid foods at the same time such as almond, nuts, cacao, rhubarb and tea, etc. Therefore these foods should be avoided to eat with spinach. In addition to spinach, you should keep away from or limit intake of celery, collards, dandelion greens, eggplant and so on. Instead drinking adequate water and taking some alkaline foods such as kelp, fruits and vegetables can promote the dissolving and discharging of too much oxalate.

Limit your oxalate intake of 40 to 50 mg each day is helpful for you. More details about kidney stone diet, you can talk with our online doctor directly.
