Hello, This indicates still underlying presence of calculus in the urinary system. Strongly recommend to take repeat ultrasound examination to find the current location of the stone and management plan decisions accordingly rather than taking old tablets empirically as you were better with them. Till then you should: • Drink plenty of liquids preferably boiled water, coconut water, lemon juice, green tea, coffee, buttermilk, etc. • Organic citrus fruits, chewable vitamin c supplements along with cranberry sachets are really helpful Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel
