The causes of kidney failure are:
1. The elderly and children: The renal function of the elderly degenerate,
and diminished capacity of drug detoxification, high sensitivity nephrotoxic
drugs, is the cause of renal failure, hypovolemia. Hypovolemia: Bleeding due to
various reasons also causes kidney failure. Kidney and gastrointestinal fluid
out, leaving skin fluids (eg burning, excessive sweating) ect, hypovolemia
cause. When hypovolemic, reduction in renal perfusion, low GFR, while
sympathetic excitation and cause rise vasopressin renal vasoconstriction, which
further decrease GFR does induce ARF. Circulatory failure: Clash of several
causes, heart failure and other circulatory failure causes renal hypoperfusion,
GFR floor.The excessive use of antihypertensive drugs is also a cause of renal
failure.
2. After surgical: severe primary disease, the use of anesthesia and
sedation, tissue trauma, fluid loss, blood loss, and other factors make after
major surgery prone. The opportunity after cardiac surgery accretes renal
failure depends on cardiopulmonary short time and the situation of cardiac
function restored. Obstetric complications: Pollution during early pregnancy
abortion: Late Stage severe hypertension induced by pregnancy, bleeding, pain
ect child, complications were easily induced, these are the reasons for kidney
failure.
3. Severe infections and sepsis: Variety cause serious infections is also
renal failure, in particular, those with sepsis may renal ischemia induced renal
toxicity mechanisms. Severe Trauma: as burns, crush injuries, severe fractures
ect because organizations infection shock and trauma, such as the release of
myoglobin likely ARF. Severe burns are a large amount of fluid loss and kidney
failure intravascular hemolysis is also one of the reasons.
4. cirrhosis and ascites: Now plasma renin - aldosterone system is activated,
vasopressin secretion increased as a result of renal sodium retention. Abnormal
liver function capacity makes drug detox to get off. At this point is likely to
cause acute renal failure if ascites too much too fast, these patients use
nephrotoxic drugs are also vulnerable to disease. Kidney disease: Chronic kidney disease can
affect self often function of the kidneys, may be due to an illness or aggravate
certain additional factors (infections, urinary tract obstruction, water and
electrolyte imbalance, use of nephrotoxic drugs etc.) inducing. Nephrotic
syndrome associated with idiopathic acute renal failure in recent years,
attention may circulating blood volume because insufficient effective protein
renal tubular obstruction, renal edema thrombosis oppression tubular and
interstitial renal vein and other mechanisms to the nephrotic syndrome
ARF, description itself renal disease should be considered as an independent
cause of kidney failure. Moreover elderly prostatic hypertrophy use of
anticholinergic drugs, renovascular hypertension using angiotensin-converting
enzyme inhibitors, abuse of non-steroidal anti-inflammatory drugs, overdose of
drugs cyclosporine and acute chemotherapy-induced hyperuricemia are also what
are the reasons for the renal failure.
5.La application of nephrotoxic drugs: The use of nephrotoxic drugs such as
aminoglycosides, contrast agents and cephalosporins, especially in the elderly,
children, dehydration, diabetes, cirrhosis, kidney diseases that are
particularly dangerous when applied, it is also one of the reasons of the
kidney.
