In simple terms, salting-out describes the precipitation of a less soluble material from a
solution in which it is mixed with other substances. For at least 2 centuries, preparative …

Hyperuricosuria has long been documented as a predisposing factor to calcium oxalate
(CaOx) stone pathogenesis. However, its mechanism is still without sound scientific …

Cement containing urine will not set. This has been common knowledge for so long that its
discovery would be impossible to trace, yet its implications for urolithiasis were not fully …

1. The effect of hyperuricosuria, simulated by increasing the concentration of dissolved
urate, on the crystallization of calcium oxalate in human urine was examined. 2. Twenty …

A critical appraisal of the evidence commonly cited to support a link between high urate
excretion and calcium oxalate (CaOx) urinary calculi is presented. Two theories have been …

A method has been developed for inducing and quantifying calcium oxalate crystallisation in
whole human urine. The propensity of a given urine to induce crystal formation was …

It is currently agreed that stone formation in the urinary tract requires supersaturation with
respect to a given solid phase. However, this principle fully applies only to stones other than …

Two major etiologic theories of urinary stones are excessive saturation of urine with
crystallizable substances or defects in inhibitors that allow relative supersaturation to occur …

Aim In recent years significant progress has been made in identifying and quantitating
physico-chemical processes involved in urinary stone formation. The ability of urine to inhibit …

An interpretation of previous and recent observation on calcium salt crystallization and
calcium stone formation provide the basis for formulation of a hypothetical series of events …
