Calculus, renal: A stone in the kidney (or lower down in the urinary tract). Also called a kidney stone. The stones themselves are called renal caluli. The word calculus (plural: calculi) is the Latin word for pebble. Renal stones are a common cause of blood in the urine and pain in the abdomen, flank, or groin.

The development of the stones is related to decreased urine volume or increased excretion of stone-forming components such as calcium, oxalate, urate, cystine, xanthine, and phosphate.
A vacuole is a cell organelle found in a number of different cell types. Vacuoles are fluid-filled, enclosed structures that are separated from the cytoplasm by a single membrane. They are found mostly in plant cells and fungi.However, some protist, animal cells, and bacteria also contain vacuoles.Vacuoles are responsible for a wide variety of important functions in a cell including nutrient storage, detoxification, and waste exportation. A plant cell vacuole is surrounded by a single membrane called the tonoplast.Vacuoles are formed when vesicles, released by the endoplasmic reticulum and Golgi complex, merge together. Newly developing plant cells typically contain a number of smaller vacuoles. plant cell vacuole is surrounded by a single membrane called the tonoplast.
