How long do i wait for results as i am so scared i can hardly sleep or function.

I  recently had a virtual colonoscopy which detected an incidental find. I am so worried I can’t even remember what they said. I believe slightly enlarged  left kidney and something to do with urine and tube. 
I had a nhs urogram two weeks ago and haven’t had any results back yet. How long do you wait for results. 
Thanks in advance to anyone that replies.
