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 is the end product of purine metabolism in humans. In animals other than mammals uric acid undergoes further degradation because of the activity of enzymes such as uricase, allantoinase and allantoinase; in some species the urea that is formed is further hydrolyzed to ammonia and CO2 by the urease of intestinal bacteria (1).

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 ...

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.

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.

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.

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.

Uric Acid Metabolism and Uric Acid Stones
2010Uric acid nephrolithiasis comprises 8–10% of patients with kidney stone disease. However, this prevalence is higher in particular ethnic populations and in certain regions of the world. The major pathophysiologic mechanism for uric acid nephrolithiasis is unduly acidic urine.

Hyperuricemia is a common complication in organ transplant recipients, and frequently is associated with chronic cyclosporine immunosuppressive therapy. Kidney and heart transplant recipients are prone to develop posttransplant hyperuricemia. Risk factors for hyperuricemia include decreased glomerular filtration rate (GFR), diuretic use, and ...
