<s>[INST] i am 64 yrs old having two stones in my right and let kidney around 7mm and 5 mm stone in my right and left kidney and both are silent stone I have been using the stonvil tablets since last 7 months along with other Aurvedic medicines for prostrate, fatty liver and sugar. The stonvil tab has not shown any improvement in reducing the size of the stonvil tablets. Can you advice me on this [/INST] Hi welcome to Chat Doctor, and thanks for your query. Ultrasound measurement of stones is not the best method. If you are worried, it is better to get a CT SCAN done to check the location of the stones. If it is confirmed as kidney stones, the sizes you have mentioned, then plenty of oral fluids is sufficient. It is better ti take reduced red meat and alcohol if you happen to do so. Wishing you good healthRegards Chat Doctor.  </s>
