calculus

 [kal´ku-lus] (pl. cal´culi) (L.)

biliary calculus gallstone.
bladder calculus vesical calculus.
bronchial calculus broncholith.
calcium oxalate calculus oxalate calculus.
dental calculus a hard, stonelike concretion, varying in color from creamy yellow to black, that forms on the teeth or dental prostheses through calcification of dental plaque; it begins as a yellowish film formed of calcium phosphate and carbonate, food particles, and other organic matter that is deposited on the teeth by the saliva. It should be removed regularly by a dentist or dental hygienist; if neglected, it can cause bacteria to lodge between the gums and the teeth, causing gum infection, dental caries, loosening of the teeth, and other disorders. Called also tartar.
gastric calculus gastrolith.
intestinal calculus enterolith.
lung calculus a hard mass or concretion formed in the bronchi around a small center of inorganic material, or from calcified portions of lung tissue or adjacent lymph nodes. Called also pneumolith.
mammary calculus a concretion in one of the lactiferous ducts.
nasal calculus rhinolith.
oxalate calculus a hard urinary calculus of calcium oxalate; some are covered with minute sharp spines that may abrade the renal pelvic epithelium, and others are smooth. Called also calcium oxalate calculus.
phosphate calculus a urinary calculus composed of a phosphate along with calcium oxalate and ammonium urate; it may be hard, soft, or friable, and so large that it may fill the renal pelvis and calices.
prostatic calculus a concretion formed in the prostate, chiefly of calcium carbonate and phosphate. Called also prostatolith.
renal calculus kidney stone.
staghorn calculus a urinary calculus, usually a phosphate calculus, found in the renal pelvis and shaped like the antlers of a stag because it extends into multiple calices.
urate calculus uric acid calculus.
urethral calculus a urinary calculus in the urethra; symptoms vary according to the patient's sex and the site of lodgment.
uric acid calculus a hard, yellow or reddish-yellow urinary calculus formed from uric acid.
urinary calculus a calculus in any part of the urinary tract; it is vesical when lodged in the bladder and renal (see kidney stone) when in the renal pelvis. Common types named for their primary components are oxalate calculi, phosphate calculi, and uric acid calculi. Called also urolith.
uterine calculus any kind of concretion in the uterus, such as a calcified myoma. Called also hysterolith and uterolith.
vesical calculus a urinary calculus in the urinary bladder. Called also bladder calculus.

Other rare intraluminal causes of SBO include gallstones that migrate from the gallbladder via a biliaryenteric fistula into the adjacent duodenum, typically lodging itself in the distal ileum to create the entity known as "gallstone ileus."
