Thanks for the query.
You have not mentioned the size of the stone. Usually if it is less than 10mm there is a chance that it may be flushed out. Drinking plenty of water is one way to help the process. There are a few medications available now which relax the muscles of the lower end of the ureter
which may help stone passage.
You need to see a urologist
who may prescribe these or advice other interventions.
Hope this helps
