renal calculus
(redirected from Renal calculi)

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.

kidney stone

 or renal calculus

Mass of minerals and organic matter that may form in a kidney. Urine contains many salts in solution, and low fluid volume or high mineral concentration can cause these salts to precipitate and grow, forming stones. Large stones can block urine flow, be a focus for infection, or cause renal colic (painful spasms). They can obstruct the urinary system at various points. Treatment deals with any underlying problem (e.g., infection or obstruction), tries to dissolve stones with drugs or ultrasound (lithotripsy), or removes large ones surgically.


renal calculus [′rēn·əl ′kal·kyə·ləs]
(medicine)
A concretion in the kidney.

As experience grows so do improvements in care: * Fewer blood transfusions are necessary as we have stopped using high-dose zidovudine in late-stage patients; * We see less peripheral neuropathy as fewer patients are on combinations involving didanosine and stavudine [2]; * We see less lipodystrophy as stavudine usage reduces; * We see fewer renal calculi and dry skin as indinavir usage reduces.
Kidney stones, also known as renal calculi, are rock like structures formed in the kidney.
