2 Chronic renal failure 3 Diagnosis 4 Causes 5 Treatment |
The most common prerenal cause of acute renal failure is hypotension or decreased blood flow, usually from shock or dehydration/fluid loss. Other causes include vascular problems such as renal artery stenosis and thrombus.
Damage to the kidney parenchyma itself can cause renal failure. This would include such things as infection, toxins and autoimmune diseases.
Postrenal problems affecting the flow of urine beyond the kidneys can result in a postrenal cause of renal failure. Thus, any disease affecting the ureters, bladder or urethra can lead to this.
Chronic renal failure, on the other hand, is not reversible. If the renal function deteriorates enough, the patient may well end up requiring dialysis or a kidney transplant on a long term basis.
