Lilly was first diagnosed with kidney and bladder stones a few years ago. She had surgery to remove her bladder stones. Unfortunately, surgery to remove kidney stones can be very dangerous and usually is only done if the stones are going to obstruct the kidney. Sadly, this was the case a couple years later for poor Lilly, and she had to have a stent placed in her ureter at the specialty center. All was well again until recently, when she came in lethargic and in pain.
