Hi, Thanks for writing in. There is a probability of a 6 mm stone in the left kidney. This is not confirmed but it is likely that the stone is not well seen and therefore written as questionable calculus. It is important to know if the stone is causing any obstruction to the flow of urine. If it is mentioned that there is no hydronephrosis then there is no obstruction and it is not a serious problem. If you want to confirm about the stone then please do a CT scan KUB region and this will show whether there is a calculus in the left kidney. Please find my suggestions for kidney stones which you can practice. These are my own opinions and I suggest this to my patients. DOs for kidney stones (i) Drinking as much as 1.5 to 2.5 liters a day may help flush out your urinary system. This will also allow small stones to pass through. (ii) Visit washrooms regularly and empty your bladder when you feel like doing urination. (iii) Please take fruits like apple, papaya, watermelon, pineapple, sweetlime, bananas and orange, vegetables like, white gourd, ladyfinger, pumpkin, pulses and legumes. (v) If you have sharp pain then you should consult your doctor and take pain reliever medications under strict supervision. DONTs for kidney stones (i) Please avoid holding urine for long intervals. (ii) Please reduce foods containing oxalates like non veg, vegetables like spinach, tomato, cauliflower, brinjals, nuts like cashew, pista and almonds. (iii) Decrease extra salt in foods. (iv) Avoid spicy pickles. (v) Please eat meat products in normal amounts, avoid eating too much.
