 Depending on the severity and duration of renal dysfunction, their may be metabolic disturbance like  acidosis and hyperkalamia. They may also be changes in the body fluid balance and effects in other body organs. There may be oliguria /anuria which the total cessation of urine production

CAUSES

Acute renal failure is due to deficiency to renal and post-renal. Pre-renal causes are due to deficiency of blood supply. They could be due to hypertension resulting from shock, dehydration or fluid loss and renal vein thrombosis.

Renal causes are due to damage of the kidney itself. This could be as a result of infection pyelonephritis which is an ascending urinary tract infection that has reaches the kidney pelvic. It could be due to acute glomerular.

Chronic renal failure is slowly progress of function failure of a period of month or years of the kidney. Chronic renal failure leads to severs illness that requires some form of replacement therapy e.g dialysis.

 

SIGN AND SYMPYOMS

Blood pressure increases due to fluid retention.

Urea creatinine and nitrogenous compound accumulate in the blood

Increase in production of red blood cells that leads to anemia

Fluid overload that may range from myoedema to life threatening pulmonary oedema

Hyperphosphataemia, which is due to the decrease in phosphate excretion and hypocalcaemia due to failure of vitamin D activation.

There is metabolic acidosis due to decrease generation of bicarbonate in the kidney.

TREATMENT

It all depend on what has caused the acute kidney failure and how severe it has become.The doctor should be able to determine this prescribe to the patient the right medication or point out the the course of action.
