Acute renal failure is caused by a variety of causes of acute kidney injury, within a few hours or days to nephron regulating function decreased dramatically, so as not to maintain fluid balance and electrolyte excretion of metabolites, and cause hyperkalemia, metabolic acidosis and acute uremic syndrome, the syndrome is called acute renal failure. From the perspective of diagnosis and treatment of acute renal failure, the causes of acute renal failure can be divided into three categories:
1 renal anterior. Insufficient effective blood volume, common in gastrointestinal fluid loss; diuretics, burns and hypoproteinemia; heart failure in heart, cardiomyopathy, valvular dysfunction, cardiac tamponade; systemic vasodilation in septicemia, allergic reactions, and anesthesia; renal artery contraction leads to renal ischemia.
2 renal parenchyma. Refers to the original disease in the kidney itself, divided into five categories: acute tubular necrosis, acute glomerulonephritis and glomerular disease, acute interstitial nephritis, acute renal parenchymal necrosis and renal vascular disease. Acute tubular necrosis, use of nephrotoxic drugs in acute renal ischemia, such as: antibiotics, amphotericin B, polymyxin, aminoglycoside antibiotics, heavy metal poisoning; industrial poisons: such as cyanide, phenol, methanol, benzene, chloroform, carbon tetrachloride, bilateral renal cortical necrosis in placental abruption, severe shock; tubulointerstitial disease, in allergic reactions, drug mediated acute infection and systemic disease; renal vascular disease, renal artery embolism and thrombosis, renal vein thrombosis and microvascular disease; glomerular disease, resulting in primary glomerular disease is progressive nephritis, nephritis, infection IgA nephropathy, mesangial proliferative nephritis. Secondary nephropathy such as lupus nephritis, purpura nephritis.
3 renal posterior. Urinary obstruction or voiding dysfunction below the renal plane. Ureteral calculi incarceration; prostatic hypertrophy; urinary tract injury and urinary tract surgery; tumor compression.
Acute renal failure is divided into three types: pre renal failure, renal parenchymal renal failure and post renal failure. Common symptoms have a fever, vomiting, shortness of breath, skin rash, swelling. Kidney disease patients in this case should pay attention to protect the body is the most important away from these toxic and harmful substances.
