What is Acute Kidney Failure

CausesofAcuteRenalFailureAcute kidney failure appears when your kidneys suddenly are not able to filter waste products from your blood. When your kidneys lose their ability to filter hazardous levels of waste may collect, and your blood’s chemical composition may get out of balance.

Acute Kidney failure- also referred to as acute renal failure or acute kidney injury- can develop rapidly over a few hours or even few days. Acute kidney failure is often most common in individuals who are already being hospitalized and particularly in certain need of intensive care

Acute kidney failure can be lethal and needs intensive treatment. However, acute kidney failure can be reversible, if you are in good health, you may regain normal or nearly normal kidney function.

akfSymptoms of Acute Kidney Failure

Signs and Symptoms of acute kidney failure may include:

  • Reduced urine output, although infrequently urine out remains normal
  • Drowsiness
  • Fatigue
  • Shortness of Breath
  • Fluid retention, producing swelling in your legs, ankles or feet
  • Chest pain or pressure
  • Nausea
  • Confusion
  • Fatigue
  • Seizures or coma in severe cases

In certain occupies acute kidney failure may cause no signs or symptoms and may be detected through lab test is done for another reason.

You see the doctor anytime you have any of these symptoms of acute kidney failure.

Causes of Kidney failure

Kidney-FunctionAcute Kidney failure can occur when:

You have a condition that shows blood flow to your kidneys
You experience direct damage to your kidneys
Your kidney’s urine drainage tube (better) become blocked, and water can not leave your body through urine.

Impaired blood flows to the kidneys

Disease and conditions that may slow blood flow to the kidneys and lead to kidney failure include

  • Blood loss
  • Blood pressure medications
  • Heart attack
  • Heart disease
  • Infection Liver Failure
  • Use of Aspirin, ibuprofen (Advil, Motrin IB other ) naproxen
    (Aleve other ) or related drugs
  • Severe allergic reaction (anaphylaxis)
  • Severe burns
  • Severe dehydration

Damage to the kidneys

These diseases conditions may damage the kidneys and lead to acute kidney failure.

  • Blood clots in the veins and arteries in and around the kidneys.
  • Cholesterol deposits that block blood flow to the kidneys
  • Glomerulonephritis, inflammation of the tiny filters in the kidney’s (glomeruli)
  • Hemolytic uremic syndrome, a condition that results from premature destruction of red blood cells.
  • Medications, such as certain chemotherapy drugs, antibiotics, dye used during imaging test, and zoledronic acid (Reclast, Zometa) used to treat osteoporosis and high blood calcium rates (hypercalcemia)
  • Multiple myelomas, a cancer of the plasma cells
  • Thrombotic thrombocytopenic pupa, A rare blood disorder
  • Toxins, such as alcohol, cocaine, and heavy metals
  • Vasculitis, and inflammation of blood vessels
  • Scleroderma, a combination fo rare diseases affecting the skin and connective tissues.
  • Urine Blockage in the kidneys

acute-renal-failure1Diseases and conditions that obstruct the passage of urine out of the body, (urinary obstructions) and can lead to acute kidney failure includeColon cancer

  • Bladder cancer
  • Blood clots in the Urinary tract
  • Cervical Cancer
  • Enlarged prostate
  • Prostate Cancer
  • Nerve damage affecting the nerves that control the bladder
  • Colon cancer

Acute Kidney Failure Risk Factors

Acute kidney failure mostly occurs in connection with another medical condition or event. Conditions that increase the risk of acute kidney failure are

  • Advanced age
  • Stops in the blood vessels in your arms or legs(peripheral artery disease)
  • High blood pressure
  • Heart failure
  • Liver diseases
  • Kidney diseases
  • Being hospitalized, particularly for a severe condition that requires intensive care.

Complications with Acute acute kidney failure include the following:

UAKD_AKD-g001Fluid buildup. Acute kidney failure may lead to a build up fo file in the lungs; which can trigger shortness of breathing.
Chest pain. If the lining that encases your heart (pericardium becomes swollen, you may experience chest pain.
Muscle weakness. When you body fluids and electrolytes, your body blood chemistry, are out of balance, muscle weakness can result.High levels of potassium in your blood are particularly dangerous.
Permanent Kidney damage Occasionally, acute kidney failure causes permanent loss of kidney function. Of end-stage renal disease. People with end-stage renal did require per month dialysis – medicinal filtration process to remove toxins and waste from the body or a kidney transplant to survive.
Death – acute and failure can result in loss of kidney function and finally death. The hazard of death is higher in people who had kidney failure.

Test and diagnosis

If you signs and symptoms suggest that you have acute kidney failure, your doctor may recommend certain test and brochures to verify your diagnosis. These may include:

Urine output measurement – The volume of urine you pass in a day may help your doctor ascertain the cause of your kidney failure.

The urine test was analyzing a sample of your, through a urinalysis, may reveal abnormalities that suggest kidney failure.

Blood test. A sample of your blood may exhibit immediately rising levels or urea and creatine – two substances used to measure kidney function.
Imaging test Imaging test such as ultrasound and computerized tomography may be used to help your doctor see your kidneys.
Removing a small of kidney tissue for testing- IN some situations, your doctor may recommend a kidney biopsy to removal a small sample of kidney tissue for lab testing. Your doctor inserts a added through your skin and into your kidney to extract the sample.

Treatments and drugs

Treatment for acute kidney Failure requires a hospital stay. Most people with acute kidney failure are already hospitalized. The extent of the hospital stay depends on the reason for your acute kidney failure and how quickly your kidney’s recovery.

Treating the underlying causes of kidney failure

Treatment for acute kidney failure includes recognizing the illness of or injury that originally damaged your kidneys. Your treatment possibilities depend on the cause of the kidney failure

Treating complications until the Kidneys improve

Your doctor will also strive to prevent complications and allow your kidneys time to heal. Neatest that helps prevent complications include:

Treatments to balance to the amount of fluids in your blood
If acute kidney failure is caused by limited fluids in your blood, your doctor may prescribe intravenous (IV) fluids. In other cases; acute kidney failure can cause you to have too much liquid, leading to swelling in the arms and legs. IN the cases your doctor may prescribe medications (diuretics) to cause your body to expel additional fluids.

Medications to Control blood potassium
If your kidneys are not properly filtering potassium from your blood, your doctor may designate calcium glucose or sodium polystyrene sulfonate (Kayexalate, Kionex) to limit the growth of high levels of potassium in your blood. Too much potassium in the blood can produce dangerous abnormal heartbeats (arrhythmias) and muscle weakness.
Medications to repair blood calcium levels. If the rate of calcium in your blood drops excessively low, your doctor may prescribe an infusion of calcium.
Dialysis to eliminate toxins from your blood. If toxins form in your blood, you may need brief hemodialysis often referred to simply as dialysis – to assist removing toxins and excessive fluids from your body while your kidneys heal Dialysis can also help remove excessive levels of potassium from the body. During dialysis, a machine pumps blood out of the body through a kidney dialyzer that separates out waste; The blood is then returned to your body.


Acute kidney failure is often difficulty in predicting or preventing. But you may reduce your risk by the taking care of your kidneys.

Pay attention to labels when taking over the counter medications. Follow the instructions for TC pain medications such as Asprin, acetaminophen (Tylenol and ibuprofen (Advil, Motrin IB others) taking excessive amounts of these medications may increase your risk of acute key failure.
Work with your doctor to prevent kidney problems- If you have kidney disease or another condition that increases your risk of acute kidney failure, such as high blood pressure or diabetes, stay on track with treatment objects and follow your doctor’s recommendation to manage the condition.
Make healthy lifestyle choices, with your diet, Be active, eat a balanced diet, if you drink, do so in moderation if at all. Avoid products with added salt and sodium, frozen foods, can soups, and fast foods. Other process foods, meats and salty snacks. Choose foods with low potassium.
