[|AI|]  Hi, welcome to Chat Doctor. Looking to your history, it seems that you have tendency to form kidney stone. Sonography is baseline investigation for kidney stone. But, sometime small stone or stone in lower part of ureter can be missed by sonography. So, my advice is to undergo CT scan. Do basic urine report with culture, S. creatinine and then consult urologist. It is necessary to remove stone which is obstructing the urine passage even if it is asymptomatic. So, don't get worried. Do above tests and you ACN get back to me also with these reports. Best wishes. TC.  Chat Doctor.
