a collection of mineral salts and protein that collect to form a solid crystalline mass
a concretion generally ranging in
a crystallization of material (stone) formed in the kidney
a crystal structure formed by excessive salts in the urine
a hard, crystal-like mass that has precipitated in the urine in the renal pelvis
a hard mass developed from crystals
a hard mass formed as a result of crystals separating from the urine and eventually building up on the inner surfaces of the kidney
a hard mineral and crystalline material formed within the kidney or urinary tract
a little rock or particulate crystal in the urinary tract formed by substances in urine
a solid lump (from as small as a grain of sand to as large as a golf ball) made up of crystals that separate from urine and build up in the inner surface of the kidney
a solid lump from as small as a grain of sand to as large as the size a golf
a solid lump that can be as small as a grain of sand and as
a solid, rock-like type of material that has formed or is present in the kidneys, ureters, or bladder
a solid piece of material that forms from crystallization of excreted substances in the urine.
A crystalline structure or calculus, that forms in the kidney. Examples are calcium oxalate, calcium phosphate, uric acid.
An accumulation of mineral salts and other substances that form a solid mass of various sizes within the kidney.
A hard mass composed of substances from the urine that form in the kidneys.
a painful solid mass in the kidney or urinary system, caused by the solidification or precipitation of a dissolved substance in the urine.
A stone in the kidney (or lower down in the urinary tract). See the entire definition of Kidney stone
A kidney stone is a hard pebble-like mass commonly composed of calcium oxalate that forms within the kidney. Some kidney stones cause pain and must be removed from the body using surgery or ultrasound techniques.
A stone that forms in the collecting system of the kidney.
A stone that develops from crystals that form in urine and build up on the inner surfaces of the kidney, in the renal pelvis or in the ureters. (Also see nephrolithiasis.)
a solid material that forms in the kidney from substances in the urine, including minerals such as calcium or body chemicals such as uric acid.
A hard mass that forms in the urinary tract and which can cause pain, bleeding, obstruction, or infection. Stones are primarily made up of calcium.
stones in kidneys. Kidney stones often occur because of a metabolic disorder or from too much calcium in the blood.
A stone (concretion) in the kidney. If the stone is large enough to block the tube (ureter) and stop the flow of urine from the kidney, it must be removed by surgery or other methods. Also called Renal Calculus. Symptoms usually begin with intense waves of pain as a stone moves in the urinary tract. Typically, a person feels a sharp, cramping pain in the back and side in the area of the kidney or in the lower abdomen. Sometimes nausea and vomiting occur. Later, pain may spread to the groin. The pain may continue if the stone is too large to pass; blood may appear in the urine and there may be the need to urinate more often or a burning sensation during urination. If fever and chills accompany any of these symptoms, an infection may be present and a doctor should be seen immediately.
Kidney stones, also known as nephrolithiasis, urolithiasis or renal calculi, are solid concretions (crystal aggregations) of dissolved minerals in urine found inside the kidneys or ureters. They vary in size from as small as a grain of sand to as large as a grapefruit. Kidney stones typically leave the body in the urine stream; if they grow relatively large before passing (on the order of at least 2-3 millimeters), obstruction of a ureter and distention with urine can cause severe pain most commonly felt in the flank, lower abdomen and groin.
