Hello Doctor's. I just wanted to ask a quick question. I was suspected of having a small kidney stone, but when i underwent an Ultrasound it showed some blockage and a swollen Kidney but no visible stone. After a week i got a CECT KUB done and everything looks good in there. there was still no detection of the stone. Should I assume it has passed as im not experiencing the same kind of pain. Although I am feeling a bit tired and  little burning still continues. My question is, is that supposed to happen? Kindly advise
