Hello........ you should get it removed ..for smaller stones doctor do lithotripsy where sound waves are directed to kidney ,it breaks stone into smaller pieces so that it flush out in urine ....if its not possible doctor remove it surgically ... You shouldn't ignore this ... Consult urologist soon.Stones that are smaller than 5mm are more likely to be able to pass successfully without requiring surgery. When a stone is larger (>6mm) and unlikely to pass successfully, Stones that are growing are more likely to lead to problems while stones that stay the same size are less likely to become symptomatic.
