12 years ago I had my first episode of having kidney stone. Now, 7 days ago, I woke up early in the morning with a very sharp and unbearable pain that started from my back(right below my ribs) and continued to the side and middle of my abdomen. The pain was so big that I wasnt able to dress myself or to find a position that would somehow ease it. They did CT scan and it turned out I had a stone in my urether just above the baldder. They let me home with pain medicine and said I need to drink lots of water so that it could help flush it. I am doing what I was told and my stone is still there. Additionaly, my right kidney started to hurt bad. I am thinking that is due to either infection forming or backflow of urine. Went to urologist yesterday. He didnt even take Xray to see where the stone is. He only put me on cirpo for 5 days to prevent infection. I am on my end wits because I need to go back to work tomorrow and I am in pain. My question is, how likely is for CT scan to misdiagnose stone? is it possible that this can be something different ? And is it possible for the stone to be stuck in the tube? I was told it was only 4mm big in size. Please help.
