Q: I had kidney stones around three years back. The doctor told me that I have bilateral calculi, with more than six stones, the maximum size being 0.6 mm. I have been taking my medicines since then and do not have any problem now. I am worried if those stones are still there and growing in my kidneys? What type of the stones are they and what precautions should I take besides drinking water?

A:To know whether your kidney stones are passed or are growing can be checked by getting a plain x-ray abdomen and an ultrasound of abdomen (KUB) done. This should confirm if stones are still there and whether there is any obstruction in the kidney. You may require Intravenous pyelography to delineate the exact position of the stones & their impact on the kidney. For dietary & medical advice you will need a metabolic work up and stone analysis (if available).
