Crystalluria 

Crystalluria refers to crystals in urine. In this video, what is shown are crystals which formed after the sample has dried. Therefore, technically, these are just crystalline structures.
Nearly all minerals have a crystalline structure beneath their surfaces. Crystalline structure has a geometric, repeating pattern of symmetric molecular structure. The arrangement of atoms forms these ordered, repeating patterns.
This sample was not produced in a laboratory, nor was it placed in a centrifuge, or stained or treated in any way for medical purposes.
Images were captured using a Swift SW380B microscope, with a Hayear HY-500 microscope camera. Most were observed using 10x and 40x objective lenses.
