Kidney stones?

I’m 16 and a week ago was diagnosed with kidney stones. I don’t know if I passed them. When I went to the hospital they said I had a kidney stone and an uti. They gave me medicine for both but I don’t feel discomfort like I did before. The only thing that hurts is when I pee and a little after I feel my urethra throbbing but that’s it. Did I pass them??
