The common causes of pre renal interstitial disease include2017-02-02 13:45
(1) hypovolemia: visible: a variety of reasons caused by bleeding, such as gastrointestinal bleeding, postpartum hemorrhage and trauma; the gastrointestinal fluid, such as severe vomiting and diarrhea, gastrointestinal decompression; loss of the secondary fluid in kidney, adrenal function, such as diabetic ketoacidosis the not congruent; for other reasons, such as burns, dehydration and excessive sweating.
(2) decreased cardiac output, such as severe congestive heart failure or low flow syndrome (cardiomyopathy, severe arrhythmia and pericardial tamponade), pulmonary embolism, etc..
The etiology of acute renal failure after renal failure is acute urinary obstruction caused by various reasons, such as ureteral calculi, papillary necrosis, urethral stricture, bladder neck obstruction, prostatic enlargement and so on.
Renal parenchymal acute renal failure is caused by many renal parenchymal diseases. According to the disease location and nature are pided into 5 categories: acute glomerulonephritis and small vasculitis, such as syndrome, acute nephritis, systemic lupus erythematosus, systemic necrotizing vasculitis, allergic purpura nephritis, hemolytic uremic syndrome, disseminated intravascular coagulation, malignant hypertension and severe PIH acute glomerular acute renal nephritis; vascular diseases, such as renal artery thrombosis, renal artery embolization, abdominal aortic aneurysm, renal vein thrombosis; acute interstitial nephritis, such as infection, allergic acute interstitial nephritis, drug allergic acute interstitial nephritis and acute exacerbation of chronic kidney disease;, such as infection, urinary tract obstruction, water electrolyte imbalance, nephrotoxic drugs application and heart failure; the acute tubular necrosis and acute renal cortical necrosis, such as severe trauma, Acute renal ischemia caused by surgery and severe infection, and the use of exogenous and endogenous nephrotoxic substances.
The main causes of post renal acute renal failure are acute urinary tract obstruction.
