Hello
Thanks for query .
Hard tiny speck tht yo have passed in urine after having UTI is most likely a urinary stone .

This can be confirmed by submitting the speck in laboratory for analysis so that further measures can be taken to prevent recurrence of stone formation .

In the mean time you can continue taking antibiotics for coupe of days ..

Ensure to drink more water .

Hello, so i peed 3 times this morning and no black flakes. Could this just be something passing through? Or should i still worry about It?

I also finished my uti medication a week after I.t was given. So i am finished with medication. No pain at all though.
