Lab results on a "stone" I passed in urine -- "unable to determine composition."

Have been passing blood in urine for several months. Think I may have passed some small stones several months ago. having intermittent back pain below ribs. kidney function is normal. Recently experienced dull to sharp pains in lower abdomen/pelvic area for a few weeks. This stopped after passing 6 small rust-clored "stones." I saved the first stone. After it dried it was more of a gray/white color, somewhat smooth/flat with a "crystal-composition look, some jagged edges. The lab tech said it looked like a potato chip but said it was hard enough to be a stone -- couldn't break it with the prong he used to poke around on it.

I am wondering why the lab wasn't able to determine the composition of the stone. Abdominal/Pelvic CT scan was normal. Scheduled for a bladder scope. Still passing blood in urine

Any ideas? Similar experiences? Questions I should ask my doctor?
