BACKGROUND Cell membranes and their lipids play critical roles in calcification. [] Key MethodRESULTS Urine as well as CaOx and CaP crystals made in the urine and various types of urinary stones investigated contained some lipids. Urine of both CaOx and uric acid stone formers contained significantly more cholesterol, cholesterol ester and triglycerides than urine of healthy subjects. However, urine of CaOx stone formers contained more acidic phospholipids. The organic matrix of calcific stones contained…

Crystallization modulating macromolecules discussed here are also prominent in cell injury, inflammation and recovery, and indicate a close relationship between inflammation and nephrolithiasis.

Biomolecular mechanism of urinary stone formation involving osteopontin

Dietary control such as low-cholesterol intake and the ingestion of antioxidative foods and vegetables have successfully reduced the 5-year recurrence rate of kidney stones.

Calcium phosphate-induced renal epithelial injury and stone formation: involvement of reactive oxygen species.

It is proposed that CaP crystals can independently interact with renal epithelium, promote sites for crystal attachment, and then either grow into mature CaP stones or create sites for CaOx crystal nucleation, retention, and stone development.

Modulators of Crystallization of Stone Salts

As a direct consequence of the renal function of water preservation urine becomes supersaturated with slightly soluble salts like calcium oxalates and calcium phosphates (1). When the supersaturation

Lithogenic activity and clinical relevance of lipids extracted from urines and stones of nephrolithiasis patients

We investigated contents and classes of urinary and stone matrix lipids, and evaluated their clinical relevance in nephrolithiasis patients. Lithogenic role of major lipid classes was explored. Urine

Calcium oxalate crystallization in untreated urine, centrifuged and filtered urine and ultrafiltered urine

It is concluded that CaOx crystallization processes in manipulated urine are extremely different, probably due to changes in macromolecular compounds.

How do stones form? Is unification of theories on stone formation possible?

It is proposed that production of reactive oxygen species (ROS) causes dedifferentiation of epithelial/endothelial cells into osteoblast type cells and deposition of CaP in the basement membrane of renal tubules or vessels.

Renal Cellular Dysfunction/Damage and the Formation of Kidney Stones

Supersaturation is the driving force behind crystal formation in the kidneys. It can, however, result only in the formation of crystals that can often be harmlessly excreted. For stone formation,



Identification of proteins extracted from calcium oxalate and calcium phosphate crystals induced in the urine of healthy and stone forming subjects

Crystallization in urine was induced by addition of an oxalate or phosphate load and no significant differences were detected between protein components of the matrices of CaOx and CaP crystals and between the crystal matrices obtained from the urine of normal and stone forming subjects.

Increased urinary excretion of lipids by patients with kidney stones.

The greater excretion of lipids may reflect the increased turnover of cells in the tubular epithelium and sloughing of cells into the urine in response to a challenge by oxalates and calcium oxalate crystals.

Intratubular crystallization of calcium oxalate in the presence of membrane vesicles: an in vitro study.

In the absence of membrane vesicles, there was no crystallization in any of the solutions within the time urine spends in the renal tubules, and homogeneous nucleation of crystals anywhere within the nephron appears unlikely.

Recent studies on red blood cells and IMCD cells that have been enriched with cholesterol and selected phospholipids suggest that crystal-membraneospholipid interactions play a major role in crystal attachment.

Regulation of renal epithelial cell affinity for calcium oxalate monohydrate crystals.

Intrarenal AA, PGs, and/or other agents that raise the intracellular concentration of cAMP may serve a protective function by preventing crystal adhesion along the nephron, thereby defending the kidney against crystal retention and stone formation.

Oxalate: from crystal formation to crystal retention.

These studies provide the first direct evidence for the role of oxalate in promoting COM crystal retention by the urothelium.

Calcium oxalate urolithiasis in the rat: is it a model for human stone disease? A review of recent literature.

In a number of respects, experimental calcium oxalate urolithiasis in the rat is similar to calcium Oxalate stone disease in man.

Contrasting effects of gentamicin and mercuric chloride on urinary excretion of enzymes and phospholipids in the rat.

The phospholipiduria induced by mercuric chloride is derived primarily from the shedding of brush border membrane fragments into the urine, and it is speculated that the origin of theospholipids making up the lysosomal myeloid body may be the endocytic vesicle that mediates the transport of aminoglycosides into the lYSosomal system.
