Hello, Im not pregnant but I have just had a kidney infection which has been treated. The GP sent me for a ultra sound due to pain I was still having. I did this last week. Today, I have only just received a letter from the hospital referring me to a urology clinic. The letter was sent out on the day I went for my ultra sound (21/05/2018). I was just wondering whether this means they've found something on my ultra sound results or whether its just protocol? Surely if it was clear they would leave it?
