Hi welcome to HealthcareMagic
Since the size of the stones are small, less than 10mm in diameter, they can be easily broken into smaller fragments by ESWL(electroshochwavelitotripsy ) method... the fragments will be expelled in the urine... Drink excess of water... . other options of treatment are Ureteroscopic removal, if the stones are present at lower par of ureter and bladder.. for more details you can consult urologist
,.Hope I have answered your question..
