Medical Definition of Renal stone 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. Kidney stones occur in 1 in 20 people at some time in their life. 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.

Osculum Osculum The osculum is an excretory structure in the living sponge, a large opening to the outside through which the current of water exits after passing through the spongocoel. Wastes diffuse into the water and the water exits through the osculum at a velocity of nearly 8.4 cm/second, carrying away with it the sponge's wastes. The size of the osculum is regulated by the myocyte. Its size, in turn, determines the amount of water flowing through the sponge. References

Critical Challenges of Renal Calculi in Women The management of ureteral calculi located between the inferior border of the sacroiliac joint and the ureterovesical junction is controversial. Proponents of both ESWL and ureteroscopy have advanced convincing arguments in favor of each technique as the first-line therapy for distal ureteral calculi.

Service Your Air Conditioner for Summer Comfort In this article the term air conditioner will apply to a heat pump or a standard air conditioner. Both benefit equally from annual service tune-ups. An air conditioner is a very tough piece of equipment. It is engineered to withstand all sorts of abuse and keep on running. This is great in most respects, but it can lead to complacency about maintenance. Like a car, air conditioners need regular tune-ups to run properly. Without regular maintenance an air conditioner loses about 5% of it’s original efficiency for each year of operation.

- Abstract. Urolithiasis (urinary tract calculi or stones) and nephrolithiasis (kidney calculi or stones) are well-documented common occurrences in the general population of the United States. The etiology of this disorder is mutifactorial and is strongly related to dietary lifestyle habits or practices.roper management of calculi that occur along the urinary tract includes investigation into causative factors in an effort to prevent recurrences. Urinary calculi or stones are the most common cause of acute ureteral obstruction.

What are phleboliths?? A phlebolith is a small local, usually rounded, calcification within a vein. These are very common in the veins of the lower part of the pelvis, and they are generally of no clinical importance. Phleboliths are masses, clots or growths that develop in the wall of a vein and are composed of calcium or lime.

Staghorn calculus (kidney) Staghorn calculi are composed of struvite (magnesium ammonium phosphate) and are usually seen in the setting of recurrent urinary tract infection with urease producing bacteria (e.g. Proteus, Klebsiella, Pseudomonas and Enterobacter).Urease hydrolyses urea to ammonium and increase in the urinary pH 3-5.taghorn calculi are radiopaque and conform to the renal pelvis and calyces, which are often to some degree dilated. When viewed on bone windows they have a laminated appearance, due to alternating bands of magnesium ammonium phosphate and calcium phosphate 5.

What is Ureterolithiasis? Ureterolithiasis is the formation of kidney stones, also known as renal calculi, in the ureters, which are muscular tubes that move urine to the bladder from the kidneys.When ureterolithiasis develops, the stones can block one or both of the ureters, causing a painful condition known as a renal colic attack.The pain from such an attack usually starts in the loin and travels through the urinary tract to the genitals as the stones are passed from the body.here are several possible reasons for the formation of the kidney stones that cause ureterolithiasis, though it is not always possible for a doctor to find a cause. Diet can play a role in the growth of stones, though it is not commonly believed to cause their formation.

Calculus (medicine) A calculus, often called a stone, is a concretion of material, usually mineral salts, that forms in an organ or duct of the body. Formation of calculi is known as lithiasis. Stones can cause a number of medical conditions. Some common principles apply to stones at any location, but for specifics see the particular stone type in question. Calculi are not to be confused with gastroliths.
