Kidney stone infection.

So, I have two kidney stones (yay) on my left side. Either 1 or 2 are infected, so I require the laser surgery. It might take another surgery to get all of it out, but I’m hoping I can do it with one shot. What should I expect? They are going to place a stent in afterwards.

I’ve had one on my right side but it was only 4mm. I’ve done the surgery before.

Also just to get a general picture, does tiredness/being sleepy a side of the infection?

Can a UTI cause the stone to be infected?
