Thanks for posting your query.
As the size of ureteric stones are very small, this may pass spontaneously.
You should consult with urologist
and may take tamsulosin and deflazacort
(if you are a male).
Once it passes into the urinary bladder
, then it passes easily through urethra.
As the size of stones are very small, there will be no difficulty in passing stones.
You should also go for work up for the development of stones as you are prone for developing renal stones
