PY - 2020 T2 - Smith & Tanagho's General Urology, 19e AB - Urinary calculi are the third most common affliction of the urinary tract, exceeded only by urinary tract infections and pathologic conditions of the prostate. They are common in both animals and humans. The nomenclature associated with urinary stone disease arises from a variety of disciplines. Struvite stones, for example, composed of magnesium ammonium phosphate hexahydrate, are named in honor of H. C. G. von Struve (1772–1851), a Russian naturalist. Before the time of von Struve, the stones were referred to as guanite, because magnesium ammonium phosphate is prominent in bat droppings. Calcium oxalate dihydrate is frequently referred to as weddellite, because it was commonly found in floor samples collected from the Weddell Sea off Antarctica. The history of the nomenclature associated with urinary stone disease is as intriguing as that of the development of the interventional techniques used in their treatment.
