Kidney Stone

False-colored SEM image of the surface of a kidney stone. Urolithiasis is a common condition, with a prevalence of about 10%. Various types of urinary calculi have been described upon their mineral content and/or their morphology. The depicted stone is made of calcium phosphate crystals.
