extrarenal uremia


uremia

(u-re'me-a) [ uro- + -emia] Intoxication caused by the body's accumulation of metabolic by-products normally excreted by healthy kidneys. See: azotemia; uremic comauremic ('mik), adjective

Etiology

Although nitrogen-containing waste products have long been considered the principal cause of uremia, other metabolic waste products (such as glycosylated wastes and byproducts of abnormal oxidation) may actually be the most important toxins responsible for uremia.

Symptoms

Symptoms include nausea, vomiting, anorexia, headache, dizziness, coma, or convulsions.

Treatment

Dialysis removes many soluble waste products that accumulate in renal failure and helps improve some conditions associated with uremia. Other uremic conditions can be alleviated with a protein-restricted diet, careful management of acid-base balance, and calcium and folate supplementation.

extrarenal uremia

Prerenal uremia.

prerenal uremia

Uremia resulting not from primary renal disease but from such conditions as disturbances in circulation, fluid balance, or metabolism arising in other parts of the body. Synonym: extrarenal uremia
