a concretion formed in the bronchi. See also bronchial calculus.

pancreatic calculus

very small (4 to 5 mm) calculi in pancreatic ducts, rare and of no pathogenic importance.

prostatic calculus

concretions of calcium phosphates and carbonates in the prostatic ducts are rare and of no clinical significance.

renal calculus

see urolithiasis.

salivary calculus

white, hard, laminated concretions in the salivary duct; a sialolith. Occurs most commonly in horses.

urethral calculus

a calculus lodged in the urethra causes obstruction of the urethra with a potential for causing rupture of the bladder or perforation of the urethra and leaking of urine into subcutaneous or retroperitoneal sites. See also urolith, urolithiasis.
