Acute renal failure during pregnancy

Acute and severe damage to the renal parenchyma caused by any reason, which causes the nephron to lose its regulating function, fails to maintain body fluid and electrolyte balance, cannot excrete metabolites, and causes hyperkalemia, metabolic acidosis, and uremia syndrome, collectively referred to as acute renal function Exhaustion. Acute renal failure (ARF) is characterized by a series of physiological and biochemical changes such as decreased urine output, metabolic disorders and uremia. The incidence of pregnancy-associated ARF is low, about 0.02% to 0.05%, but ARF during pregnancy is prone to develop bilateral renal cortical necrosis and chronic renal failure, which is an extremely serious complication in obstetrics. 2/3 are caused by obstetric diseases. Most patients present with oliguria (a urine output of less than 400 ml / d) and can also present with non-oliguric acute renal failure (a urine output of more than 1000 ml / d). However, regardless of the amount of urine, a progressive increase in blood urea nitrogen and creatinine occurs within a few days to weeks; urine chemical components and / or microscopic examination abnormalities can be found in all patients with acute renal failure.
