 [kal´ku-lus] (pl. cal´culi) (L.)
an abnormal concretion, usually composed of mineral salts, occurring within the body, chiefly in hollow organs or their passages. Called also stone. See also kidney stone and gallstone. adj., adj cal´culous.
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.

Patient discussion about renal calculus

Q. Why do i get kidney stones? I am 38 and have had three stones pass so far. Is it the coffee, the meat, the stress, or the damned DNA?! My uncle is in his 50s and has passed over 30 stones!

A. Kidney stones are very common and even without the genetic or familial background people tend to get them. Of course, the more family predisposition you have, the higher are your chances of developing them, which is probably why you did. Also, a diet rich with dairy and calcium can cause your body to store excess calcium, that tends to calcify and create stones. Not drinking enough fluid is also one of the reasons.

Q. Would kidney stones affect a PSA reading? Would drinking lots of grapefruit juice affect a PSA reading? My husband's PSA reading jumped from a 4.2 to a 17 in @ 2 years' time. How can that be? This man takes all sorts of supplements and really watches his diet. He also takes good care of his body, and does NOT look or act 68.

A. You should get your parathyroid gland checked out. Your calcium level might be causing the kidney stones.

Q. How can i overcome kidney ache? in the morning it appears.after wake up.

A. First of all, it is important to distinguish kidney ache from lower back ache. If you have ever suffered from kidney problems or infections, it might be advisable to see a doctor, and rule out an infection. However, if you are otherwise healthy, and have been experiencing back pain after you wake up, it is very much possible your pain is not from the kidneys, but from the muscles of your back. In this case, some exercise on a daily basis to help strengthen your lower back can very much ease the pain you're experiencing.

The commonest indication was the renal calculus disease.
Out of 62 cases of renal calculus, 13 cases were treated surgically in the present study.
X-ray KUB performed when renal calculus disease or emphysematous pyelonephritis were suspected.
These were acute kidney injury, renal calculus disease, cystic kidney diseases, Malignancy, Glomerulonephritis, Ischemic nephropathy, chronic tubulointerstitial nephritis with distal RTA, Pyelonephritis.
Other causes of Non-diabetic renal disease include Glomerulonephritis (23%), Pyelonephritis (12%), Cystic kidney disease (11%), renal calculus disease (11%), Malignancy (8%), Ischemic nephropathy (4%), Chronic interstitial nephritis (4%).
Patients presented to the outpatient clinic with clinical features suggestive of renal calculus disease underwent ultrasonography and X-ray KUB as preliminary diagnostic modalities along with a urine routine.
RESULTS: There were 500 patients with renal calculus disease.
The possibility of combined anterograde (Percutaneous) and retrograde (Transurethral) management, thanks to the flexible ureteroscope and cytoscope, has given the standard PCNL greater access to calyces which were not reached with rigid nephroscopy, while allowing to complete renal calculus treatment with only a single percutaneous access site in most cases.
At the same time, the development of new technologies (lasers) and improved flexible endoscopes have led us to the current situation where the treatment of renal calculus is seeking least invasive and more effective techniques, retrograde intrarenal surgery (RIRS).
The CT scan images revealed the characteristic appearance of calcium containing renal calculus. The renal calculus found in our case appeared to be unusually large.
Some metabolic conditions, such as distal renal tubular acidosis, hyperparathyroidism, primary hyperoxaluria also lead to renal calculus formation.
