Welcome to healthcaremagic forum..
stones are often asymptomatic and do not require any treatment. With proper hydration they get flushed out. Treatment is planned if symptoms occur...
The treating options are planned based on the size and the location of the stone.
A stone of less than 10mm usually gets flushed out. Plenty of water intakes with or without use of diuretics are all that is needed. Stones bigger in size would need therapeutic management - ECWL or cystoscopic removal.
In your case, since the size of the stone is smaller, such treatment strategies will be planned only if you persist to have symptoms..
Consult an urologist
who will guide you through this.
