Introduction: Why Focus On Recovery

While acute renal impairment is sometimes thought of as a relatively trivial insult defined purely by changes in serum creatinine, the introduction and subsequent acceptance of the concept of acute kidney injury has gradually alerted critical care and nephrology clinicians to potential late complications in AKI survivors. It is well recognised that progressive or persistent impairment in renal function may occur following an episode of AKI, with the potential to progress to end-stage kidney disease with dialysis dependence. However, the outcome from an episode of AKI cannot simply be regarded as the binary administration for chronic renal replacement therapy or recovery. Several authors have highlighted the substantial risk of development and progression of chronic kidney disease , short of ESKD which is in turn strongly associated with increased short- and long-term mortality . This association does not necessarily implicate causation but could also indicate a common underlying disease process . The question thus arises What do we mean by renal recovery after AKI? Furthermore, in the absence of an effective therapy to alter the acute course of established AKI, our current focus should be turned towards both AKI prevention and promotion of kidney repair in the recovery phase.

Can A Damaged Kidney Repair Itself Causes & Treatment

Kidney damage is divided into two types:

  • Acute kidney disease or acute kidney failure: Damage has occured in a short period, such as in hours or a few days
  • Chronic kidney disease or chronic kidney failure: Damage has occured over several months or years

While a damaged kidney typically cant repair itself, the condition can be treated if caught early. Acute kidney failure can be reversed with prompt hospitalization, although the recovery process can take weeks to months and requires regular monitoring, diet modifications, and medications.

Chronic kidney failure, however, is often irreversible. Chronic kidney disease occurs when kidney damage worsens over time. There is no cure for CKD other than dialysis and kidney transplant.

Preliminary studies on animals have shown regeneration of kidneys with stem cell therapy, but more research is needed to support the use of stem cell therapy in the treatment of kidney failure.

Symptoms Of A Bruised Kidney

89 best images about Health

A bruised kidney is also called a renal contusion. One of the main symptoms is blood in the urine. This is called hematuria. It can be enough blood to be seen by the naked eye, or the amount of blood may be seen only by a microscope.4 Other symptoms of a bruised kidney include abdominal pain and bruising on the back of the abdomen.5

Kidney injuries can cause other, more severe symptoms. If, in addition to blood in the urine, you have nausea, vomiting, fever or increased heart rate, you should go to the emergency room immediately.

Dialysis For Kidney Failure

Dialysis artificially removes waste from your blood. There are two forms of dialysis haemodialysis and peritoneal dialysis. Peritoneal dialysis is further broken down into two main types, continuous ambulatory peritoneal dialysis and automated peritoneal dialysis .The choice of dialysis method depends of factors such as your age, health and lifestyle. Over 2,000 Australian adults start renal replacement therapy each year.

When Things Go Wrong

A little more than 1 in 10 Americans over the age of 20 show evidence of kidney disease. Some forms of kidney disease are progressive, meaning the disease gets worse over time. When your kidneys can no longer remove waste from blood, they fail.

Waste buildup in your body can cause serious problems and lead to death. To remedy this, your blood would have to be filtered artificially through dialysis, or you would need a kidney transplant.

What Do The Kidneys Do

The kidneys have several jobs. One of the most important is helping your body eliminate toxins. The kidneys filter your blood and send waste out of your body in urine.

The kidneys are bean-shaped organs about the size of your fist. They sit under your ribcage, toward your back. Most people have two working kidneys, but people can live well as long as at least one is working correctly.

When the kidneys dont work effectively, waste products build up in your body. If this happens, you might feel sick. In the most serious situations, kidney failure can be life-threatening. However, many people can manage kidney failure with the right treatment.

Prognosis For Acute Kidney Injury

Heal Kidney Damage

Acute kidney injury and its immediate complications, such as water retention, high acid and potassium levels in the blood, and increased urea nitrogen in the blood, can often be treated successfully. Typically, prognosis is favorable for people whose acute kidney injury is due to decreased blood flow because body fluids have been lost through bleeding, vomiting, or diarrheaconditions that are reversible with treatment. Prognosis is worse for people in whom some other organs are failing at the same time.

Is Ibuprofen Bad For My Kidneys

While NSAIDs rarely affect the liver, they have important adverse effects on the kidneys that you should know about. Here is the science behind the problem.

Ibuprofen and other NSAIDs block prostaglandins, natural body chemicals that normally dilate blood vessels leading to the kidneys. Blocking prostaglandins may lead to decreased blood flow to the kidneys, which means a lack of oxygen to keep the kidneys alive. That can cause acute kidney injury.

Acute kidney injury can occur with any NSAID, though seems to be a bigger culprit. In one study, folks who took NSAIDs had twice the risk of acute kidney injury within 30 days of starting to take the medications. People with existing kidney problems more often get in trouble.

The good news is these effects are reversible if you stop taking NSAIDs.

Remember, acute kidney injury from NSAIDs doesnt cause any symptoms. if you are taking ibuprofen for long periods of time, its not a bad idea to have a check of your kidney function with a quick blood test. The test may show a rise in creatinine if your kidneys are being affected, usually seen within the first 3 to 7 days of NSAID therapy.

What Are The Symptoms Of Kidney Failure

When your kidneys begin to fail, there are often little to no outward symptoms. Often, your doctor will find that you have early stages of kidney failure during laboratory tests or examinations for some other health condition.

If you do experience symptoms, however, they may include:

  • Less urine than normal
  • Water weight accumulation causing your legs, feet, and ankles to swell
  • Feeling like youre going to vomit
  • Twitching muscles
  • Pain in the stomach or back

Can A Kidney Infection Cause Abdominal Pain With No Back Pain

Enlarged or infected kidneys can cause inflammation towards the front of the body in addition to the back. If you only have abdominal pain with no back pain, that is not likely to be related to the kidneys. 4

If you are having pain across these areas, it is most likely caused by an injury to the back muscles, not the kidneys. These are common areas of back pain and it is more common for back pain to spread across this whole region than for kidney pain to spread in this way.

Kidney pain is discomfort that comes from the area where your kidneys are. Its often described as a dull ache, you feel in your sides, back, or belly. But pain in these areas isnt always a sign of a kidney issue. Its easy to mistake kidney pain for ordinary back pain.

What Happens If You Have A Hole In Your Kidney

These 10 Common Bad Habits will Destroy Your Kidneys

As blood flows through the blood vessels, small molecules such as waste products squeeze through the holes. These waste products become part of the urine. Useful substances, such as protein and red blood cells, are too big to pass through the holes in the filter and stay in the blood. Diabetes can damage this system.

What Is The Treatment For A Kidney Infection

Kidney infections can lead to serious complications if untreated so it is important to see a doctor and not wait to see if the infection goes away on its own. Treatment for kidney infections depends on the severity of the infection and the patients overall health.

Treatment for kidney infections includes:

  • If pain is mild and patients can eat and drink, oral antibiotics may be prescribed to take at home
  • The choice of antibiotic depends upon the bacteria causing the infection and the severity of the infection
  • Hospital treatment
  • If a patient has a high fever, severe pain, or cannot keep down food/fluids, intravenous antibiotics and fluids will be given in a hospital
  • Pregnant women with kidney infections are usually hospitalized
  • Kidney Failure From Bleeding

    Significant bleeding within a small period of time almost always results in some degree of kidney failure. Examples of significant bleeding that can cause reversible kidney failure are: excessive bleeding during surgery, bleeding from trauma, internal bleeding inside the stomach or intestines, an unstoppable nose bleed, heavy bleeding after childbirth, etc. The degree of kidney failure is proportional to the amount of blood loss. These types of bleeding almost always make you end up in the hospital. The good news is that most kidney failures from bleeding can be reversed with treatment. All we need to do to reverse the kidney failure in this situation is stop the bleeding and transfuse blood as required. Once the blood volume is properly restored, kidneys start to function normally.

    Eating A Healthy Diet

    In general, a heart-healthy Mediterranean-style diet is best, says Erin Rossi, RD, a nutritionist who specializes in kidney disease at the Cleveland Clinic. A 2014 study in the Clinical Journal of the American Society of Nephrologyfound that this sort of eating pattern reduces the risk to develop chronic kidney disease by about 50%.

    All patients with CKDeven at the early stagesneed to watch their salt intake since even slight damage to your kidneys can affect how it filters sodium, adds Rossi.

    Follow the recommendation of groups like the American Heart Association and NKF and consume under 2,300 milligrams a day. You may also want to moderate your daily protein intake slightlygenerally, the rule of thumb is 0.8 grams per kilogram of body weight or roughly 55 grams of protein a day for a 150-pound person, says NKF. In the later stages of kidney disease, you may need to restrict potassium and phosphorous as well.

    How Is Kidney Failure Treated

    7 Awful Habits That Can Damage Your Kidney Health!

    Treatment options vary and depend on the cause and extent of the disease.

    • Acute renal failure: Cause of the disease is treated to normalize kidney function. Dialysis may be needed for a short time.
    • Chronic renal failure: Treating chronic medical conditions can slow the progression of kidney failure. However, once the kidneys fail completely, treatment options are limited to dialysis or a kidney transplant.

    Options for treatment include treating the cause of renal failure and replacing renal function:

    • Dialysis: Blood is pumped through a machine that filters out waste and excess fluid and then returns the blood to the body. Dialysis does not cure kidney failure, but it may help improve a patients quality of life. There are two types of dialysis:
    • Hemodialysis: A catheter is inserted into one of the veins in the neck, arm, or leg. Hemodialysis is most often performed at a hospital or dialysis clinic 3 times a week for 3-4 hours at a time.
    • Peritoneal dialysis: Uses the lining of the abdomen to filter the blood using a dialysis solution and catheter. This treatment can be done at home.
  • Kidney transplant: A kidney transplant is the most complete and effective way to replace kidney function but may not be suitable for all patients. In kidney transplant surgery, doctors use a healthy kidney from a living donor or deceased donor to replace the damaged kidney in the patients body. Patients can live well with one healthy kidney.

    Pitfalls In Evaluation Of Recovery

    Assessment of baseline function

    An adequate definition of renal recovery requires a reliable assessment of baseline kidney function to distinguish non-recovery from pre-existing CKD. Efforts to obtain baseline kidney function, e.g. from the primary care or referring specialists, are therefore of utmost importance. The mean outpatient serum creatinine or, failing this, the most recent SCr measured between 7 and 365 days prior to the start of the acute illness is generally considered the best reflection of baseline kidney function . Extremes in muscle mass or dietary protein intake may affect SCr independent of kidney function. Although use of cystatin C and cystatin-based eGFR equations may reduce this problem , a baseline cystatin C level is rarely available. Another potential shortcoming of SCr, and the derived eGFR, is insensitivity to detect mild underlying CKD and the inability to detect the pre-existing presence or absence of renal functional reserve .

    Defining the population

    While most studies on renal recovery exclude prior ESKD , the handling of pre-existing CKD is variable. Furthermore, recovery has been reported in different populations . Whether recovery should be evaluated in all AKI patients or in survivors only depends on the setting. In a clinical trial evaluating an intervention to improve recovery, mortality should be treated as a competing endpoint. However, recovery in survivors may also be relevant to assess at the bedside .

    Timing of recovery assessment

    Need To Better Understand The Sequence Of Events In Tubular Recovery

    In summary, the tubular recovery after AKI is vital for the recovery of kidney function including improvement of GFR, and likely determines which patients fully recover from AKI or progress to CKD. There is a need to better understand the processes of tubular cell proliferation and repair, including strategies to intervene. The temporary inhibition of selected tubular transport processes, possibly in selected nephron regions, may provide an opportunity to improve tubular cell energetics and facilitate tubular cell recovery with consequences for kidney outcome.

    What Is The Difference Between Acute Kidney Injury And Chronic Kidney Disease

    Within the names of the diseases, acute kidney injury implies a quick onset of disease, while chronic kidney disease suggests progression over a longer period of time. Acute kidney injury also has a high mortality of around 50%.

    But beyond that, the more important distinction to make is that chronic kidney disease means the kidney dysfunction the patient has is permanent and irreversible. Whereas acute kidney injuries have a chance to recover potentially back to normal kidney function. We have many cases of dogs and cats with creatinine levels over 800 that recover to non-azotaemic states, occasionally even with some decent concentrating ability.

    However, to achieve this the patient often requires a lot of veterinary support during the recovery phase and most importantly initiation of these supportive measures must be done as soon as possible, before the damage caused by the acute kidney injury becomes permanent meaning we are trying to prevent chronic kidney disease, or minimise the degree of chronic kidney disease a pet is left with.

    Because of this chance for recovery it is very important to distinguish between acute kidney injury and chronic kidney disease.

    Which Patients Require Follow

    It is not just foods and drinks that we take can affect our kidneys ...

    Follow-up for development of CKD should be considered in all patients who developed AKI, irrespective of the apparent degree of renal recovery. Importantly, while only a small proportion of AKI survivors may develop ESKD over time, many instead die, especially from cardiovascular causes . CKD is indeed strongly associated with cardiovascular morbidity and mortality . In younger survivors, development of hypertension and cardiovascular disease may accelerate CKD progression, so that ESKD may develop after many years even if there is an apparently good initial recovery. Thus, in all groups of AKI survivors there is great potential for interventions to improve longer-term outcomes.
