Urinary tract stones were known in prehistoric times. The oldest stone was unearthed in upper Egypt, dated approximately 4800 B.C. (Shattock, 1905). Stones have been discovered from Egyptian mummies of different dynasties (Miller, 1929; Wesson, 1935; Guthrie, 1946; Sigerist, 1951; Butt, 1956).

Uric acid nephrolithiasis may be the final manifestation of various pathophysiological processes. Recent advances in renal urate transport have elucidated mechanisms by which hyperuricosuria occurs. However, in most uric acid stone formers the primary pathophysiologic defect is an excessively acidic urine pH rather than hyperuricosuria.

Uric acid, the end product of purine metabolism, is excreted predominantly by the proximal tubules. Abnormal serum levels of uric acid are due to alterations in production or excretion. Fractional excretion of uric acid is helpful in determining the underlying etiology of hypouricemia or hyperuricemia in children.

Increased levels of uric acid are associated with cardiovascular disease and the metabolic syndrome. They may predict clinical outcomes and also the onset of hypertension, though it is less clear that hyperuricaemia can be regarded as an independent risk factor given its clustering with other well-recognised factors.

Hyperuricemia is a common complication in organ transplant recipients, with a higher incidence in kidney and heart recipients. Risk factors for post-transplant hyperuricemia include reduced glomerular filtration rate, diuretic use, cyclosporine therapy, increasing age at transplant, obesity, and metabolic syndrome, as well as the presence of ...

Nephrolithiasis is a common condition in the general population. About 5-10% of all kidney stones is composed of uric acid, however the prevalence of uric acid stones significantly increases among patients with obesity, diabetes or metabolic syndrome.

A link between serum uric acid and the development of hypertension was first hypothesized in the 1870s. Although numerous epidemiologic studies in the 1980s and 1990s suggested an association, relatively little attention was paid to it until recently. Animal models have suggested a two-step pathogenesis by which uric acid initially activates the renin ...

Current Hypertension Reports, 2006
Epidemiologic studies published during the past 3 years support the possible role of uric acid in the onset of essential hypertension. Data from several large, longitudinal cardiovascular disease studies indicate that elevated serum uric acid is a predictor of incident hypertension and blood pressure progression.

Current Opinion in Nephrology and Hypertension, 2003
The goal of this article is to review the physiology and describe newly defined molecular mechanisms that are responsible for renal urate transport.Four complementary DNAs have recently been cloned whose expressed proteins transport urate. Two of these proteins have been localized to the apical membrane of proximal tubular cells: one, a urate ...

Increased uric acid level is a key clinical feature of preeclampsia; higher levels correlate with significant maternal and fetal morbidity and mortality. The cause of hyperuricemia and its specific role in the pathogenesis of preeclampsia, however, remain unclear.
