CT showed no stones, but the Ultrasound found 6 stones and a cyst.

Hey there stoners community 🙂

I'm new around here, and only just recently got diagnosed with kidney stones after they did a US of my kidneys for a whole other reason. They found 6 stones 0.5cm 0.55 cm and and a whole lot of 0.4 cm stones bilaterally, along with a cyst. Here's the thing though, I also had a CT done around 7 months ago and was told it was "clear", no stones were found whatsoever. Then after my ultrasound a month ago my pcp recommended I go do the ct again. Just recieved my results and it clearly states there is no stones at all. So that's 2 cts saying no stones, and 1 ultrasound saying there is a whole bunch of them. but the pain is there and it's only mild. So I'm a lil lost while I wait for my urology appointment.

Has anyone else here dealt with the same kind of issues?
