hyperoxaluria

hyperoxaluria
[hi″per-ok″sah-lu´re-ah]an excess of oxalates in the urine, which can lead to formation of kidney stones. Called also oxaluria.
enteric hyperoxaluria formation of calcium oxalate calculi in the urinary tract, occurring after extensive resection or disease of the ileum, due to excessive absorption of oxalate from the colon.
primary hyperoxaluria an autosomal recessive disorder characterized by urinary excretion of oxalate, with nephrolithiasis, nephrocalcinosis, early onset of renal failure, and often a generalized deposit of calcium oxalate.
hy·per·ox·a·lu·ri·a
(hī'pĕr-ok'să-lyū'rē-ă),Presence of an unusually large amount of oxalic acid or oxalates in the urine; renal stones may occur.
Synonym(s): oxaluria

primary hyperoxaluria an inborn error of metabolism with defective glyoxylate metabolism, excessive urinary excretion of oxalate, nephrolithiasis, nephrocalcinosis, early onset of renal failure, and often a generalized deposit of calcium oxalate.
hyperoxaluria
(hī′pər-ŏk′sə-lo͝or′ē-ə)n.
The presence of an unusually large amount of oxalic acid or oxalates in the urine.
hyperoxaluria
[-ok′səloo͡r′ē·ə]
an excessive level of oxalic acid or oxalates, primarily calcium oxalate, in the urine. The cause is usually an inherited deficiency of an enzyme needed to metabolize oxalic acid, which is present in many fruits and vegetables, or a disorder of fat absorption in the small intestine. An excess of oxalates may lead to the formation of renal calculi and renal failure. Treatments include pyridoxine, forced fluids, and a low-oxalate diet.
hyperoxaluria
A condition characterised by excess urinary oxalate (formula C2O4), which may lead to calcium oxalate stones in the pelvicalyceal system or urinary bladder.Aetiology
Acute tubular necrosis, enteric hyperoxaluria, cystic fibrosis, coeliac disease, diabetes, foods (e.g., beef greens, rhubarb, spinach, beets, chard, okra, peanuts, chocolate, pecans, tea, carrots), short bowel syndrome.
Management, primary hyeroxaluria
High-dose pyridoxine, orthophosphate, magnesium, increased fluid volumes, glycosaminoglycans (pentosan polysulfate), dialysis.
Management, secondary hyeroxaluria
Calcium supplements, iron, aluminium, magnesium, potassium citrate, cholestyramine, diet (reduced fat, low meat, low oxalate foods).

hyperoxaluria, primary,
n an inherited deficiency of the enzyme that metabolizes oxalic acid, resulting in an excessive level of oxalic acid or oxalates in the urine.
hyperoxaluria
an excess of oxalate in the urine; occurs in dogs in association with oxalate urolith formation.
primary hyperoxaluria
inherited metabolic defect in cats. Characterized by heavy deposits of oxalates in renal tubules, leading to oxalate nephrosis and fatal uremia before the patient reaches a year of age.
