Is it a UTI or kidney stone. Stone!

From last week I am having pain and burning sensation while passing urine. I have a history of kidney stones and this seems like how stone is stuck in the urethra . I was drinking a lot of water hoping to pass it. Yesterday I got some pain in my left side kidney so I went for an ultrasound today . The doctor checked and said there is nothing in the left kidney and in the urethra he was not able to see any stone but some swelling in the right kidney . He suggested that I go for a urine test for a potential UTI. also he said it can be a stone but may be so small taht it's not visible in ultrasound. I am still having a lot of sharp pain while passing urine. Attached are my urine test reports. Can some one please identfy if it's a UTI or just a passing stone
