Thanks a lot

Few weeks back i got a mild pain on my left lower abdoment

on consulting the doctor, i was told that there may be a possibility of a small stone

which could be treated with consumption of water to 3 lts per day (min)

i did follow it

and now i do not have a pain

but out of curosity i did take an ultrasound on my abdoment

the doctor happened to find that on my lower abdomen, there are 2 small stones

and its not obstructing as such

do i need to undergo treatement from a urologist?

or consumption of water will help to resolve this problem?

Please advise
