Causes and symptoms of acute tubular necrosis

Damage or destruction to tube-like structures known as tubules in the kidneys can bring about the development of acute tubular necrosis (ATN) and subsequently, acute kidney failure.

What causes acute tubular necrosis (ATN)?

A lack of supply of oxygen to the cells in the kidney is the most common cause of this condition. The reason as to why oxygen may not reach the cells and tissues of this organ could be restriction or blockage of the pathways. When this happens, the kidneys get damaged. Dehydration is the most important cause of ATN which may be because of loose motions, vomitings, heat stroke etc.

Health conditions such as diabetes, heart attack, and stroke can bring about a decrease in blood flow to the organs resulting in ATN and death of cells. Similarly, the presence of toxic substances in the blood can also lead to tubules damage and change the way the cells function in the tubules.

Other causes that may lead you to develop ATN may be medications, radiology dyes, anesthetics and chemicals that cause your body to react adversely.

In addition to these causes, a number of factors can put you at risk of ATN and there are:

- An injury to the body, more specifically your kidneys can cause clotting of the blood vessels
- An adverse response to blood transfusion
- Instances of septic shock can slow down blood flow to the organs
- A major surgery that can interrupt blood supply to the organs

What are the symptoms of the condition?

The symptoms associated with the condition can vary depending on the severity of the problem.

You may experience:

- Troubles in waking up
- Drowsy feeling even during daytime
- Feelings of lethargy
- Feelings of excessive thirstiness
- Problems with urination
- Fluid retention problems
- Instances of confusion
- Feelings of nausea



Can Acute Tubular Necrosis Cause Kidney Failure?

At a point when our bodies process the protein we eat, the procedure creates waste products. In kidneys, millions of tiny blood vessels act as filters since they have even tinier holes in them. As blood flows through these vessels, little molecules such as waste items may press through the gaps. These waste items turn out to be a part of the urine. Helpful substances, such as protein and red blood cells are too enormous to go through the gaps in the filter and stay in the blood.

Diabetes and kidneys: Diabetes can harm the kidneys. Abnormal amounts of glucose make the kidneys filter a lot of blood. After a couple of years, they begin to spill and helpful protein is thereby, lost in urine. Having low protein levels in the urine is called micro albuminuria.

Medication: When kidney disease is analyzed on time, during micro albuminuria, a few medications may keep kidney disease from getting worse. Having elevated levels of protein in the urine is called macro albuminuria. When kidney disease is looked up some other time during macro albuminuria, end-stage renal disease (ESRD) usually follows.

Causes: Strain on the organs may cause the kidneys to lose their filtering capacity. Waste items then begin to develop in the blood. Finally, the kidneys start to fail. This failure, ESRD, is intense. A patient with ESRD needs a kidney transplant or a blood filtration by a machine (dialysis).

Other complications: Individuals with diabetes will probably have other kidney-related issues such as bladder infections and nerve damages in the bladder.

Preventing complications: Not everybody with diabetes goes through a kidney disease. Elements that can impact kidney disease improvement include genetics, blood-sugar control and blood pressure. The more a person keeps diabetes and blood pressure under control, the lower the chances of getting a kidney disease.

Keeping your glucose level high can counteract diabetic kidney problems. Research has demonstrated that blood glucose control diminishes the danger of micro albuminuria by 33%. For individuals who suffer from micro albuminuria have now a reduced danger of advancing to macro albuminuria. Different studies have recommended that blood glucose control can reverse micro albuminuria.

Treatment: Essential treatments for kidney infection include control of blood glucose and blood pressure. Blood pressure dramatically affects the rate at which the condition progresses. Indeed, even a gentle increase in blood pressure can rapidly aggravate a kidney infection. Four approaches to bring down your blood pressure are:

Shedding pounds
Eating less salt
Maintaining a strategic distance from liquor and tobacco
Exercising regularly
A low-protein diet can decrease the amount of lost protein in the urine and increase the protein levels in the blood. Never begin a low-protein diet without talking to your physician or nephrologist.

Diabetes & Kidney Problems - Know The Complications!

A bladder infection is a bacterial infection within the bladder. Some people call a bladder infection a urinary tract infection (UTI). This refers to a bacterial infection anywhere in the urinary tract, such as the bladder, kidneys, ureters, or the urethra. While most cases of bladder infection occur suddenly (acute), others may recur over the long term (chronic). Early treatment is key to preventing the spread of the infection.

What causes Bladder Infection?
Bacteria that enter through the urethra and travel into the bladder cause bladder infections. Normally, the body removes the bacteria by flushing them out during urination. Men have added protection with the prostate gland, which secretes protective hormones as a safeguard against bacteria. Still, sometimes bacteria can attach to the walls of the bladder and multiply quickly. This overwhelms the body s ability to destroy them, resulting in a bladder infection.

Other factors can increase the risk of bladder infections for both men and women. These include:

Advanced age
Insufficient fluid intake
Surgical procedure within the urinary tract
A urinary catheter
Urinary obstruction, which is a blockage in the bladder or urethra
Urinary tract abnormality, which is caused by birth defects or injuries
Urinary retention, which means difficulty emptying the bladder
Narrowed urethra
Bowel incontinence
Pregnancy
Diabetes
Symptoms for Bladder Infections

Cloudy or bloody urine
Urinating more often than usual
Foul-smelling urine
Pain or burning when urinating
A frequent sensation of having to urinate, which is called urgency
Cramping or pressure in the lower abdomen or lower back
Bladder infections can also cause back pain. This pain is associated with pain in the kidneys. Unlike muscular back pain, you might experience pain on both sides of your back or the middle of your back. Such symptoms mean the bladder infection has likely spread to the kidneys. A kidney infection can also cause a low fever.

Bladder Infections - Decoding one of the Most Common Gynae Problem in Women

The presence of blood in urine is known as Haematuria. It is categorized under 2 types:

    Macroscopic haematuria, which means the patient has seen blood.
    Microscopic dipstick haematuria, which means blood is identified by urine microscopy or by dipstick testing either in association with other urological symptoms (symptomatic microscopic haematuria) or during a routine medical examination. It has been variably defined as 3 or more , 5 or more or 10 or more Red Blood Cells (RBCs) per high - power field.

Urological and other Causes of Hematuria

    Cancer: Bladder, Kidney and Prostate Cancer
    Stones: Kidney, Ureteric
    Bladder Infections: Bacterial tuberculosis, infective urethritis Inflammation
    Interstitial Cystitis Trauma : Kidney, bladder, urethra, pelvic fracture causing urethral rupture
    Renal cystic disease: (e.g. medullary sponge kidney)
    Other urological causes: Benign prostatic hyperplasia, vascular malformations
    Other medical causes of haematuria: anticoagulation therapy (e.g. asprin, anti platelet therapy) Nephrological Causes: more likely in children and young adults, proteinuria; red blood cell casts.
    Urological investigations: Urine culture, urine cytology, cystoscopy, renal ultrasonography and intravenous Urography and CT Urography.

Management of haematuria depends on the cause as determined by the urologist.

Causes and Treatment for Hematuria

A lot of bad things can and do happen when the kidneys fail.  The kidneys are vital for proper bodily functioning because they filter liquid and solid waste products out of the blood and allow vital chemicals (which the body needs for functioning) to flow into the body through the bloodstream.  People can become very sick when the kidneys either fail to perform these functions or fail to perform them properly.  Many people will get chronic kidney disease, therefore, they need to know what the causes and symptoms are in order to treat, and even prevent these diseases from occurring.

People who suddenly experience the following symptoms should see a nephrologist as soon as possible for a medical examination:  blood or protein in the urine, kidney stones, acute kidney injury, kidney infections, and/or pain, and Hepatitis C and kidney disease.  

Blood in the urine can be a sign of kidney problems which can lead to kidney disease.  Additionally, people who urinate frothy or bubbly urine, or have swelling in the hands, face, and feet should see a doctor because this is a sign of protein in the urine.  Protein in the urine can be detected by a urine test.  Kidney stones can be very painful and are problematic.  They are caused by mineral buildup in the kidneys.  Men and white people tend to get kidney stones more, and they can cause blood in the urine, painful urination, sharp lower abdominal or back pain, and nausea and vomiting.

Acute kidney injury occurs when the kidneys stop functioning altogether in a short period of time.  Because this disease can be deadly, those with this disease should get immediate medical help.  Usually, the very sick patients in hospitals get this disease, but it can also be caused by certain medicines, injury, or infections.  This type of kidney disease is easily reversible.  

Symptoms include

Not passing enough urine when urinating
Leg, ankle, or feet swelling
Fatigue
Breathing problems
Confusion
Nausea, and chest pressure or pain. 
Kidney infections tend to be caused by bacteria that have spread from the urinary tract.  Women, because of their anatomy, tend to get kidney infections more than men. 

Symptoms include:

Fever
Vomiting
Back, side or groin pain
Chills
Nausea
Frequent urination
Frequent urges to urinate
Painful or burning urination
Pus or blood in the urine
Cloudy or foul-smelling urine
Kidney pain in the lower back or sides can signify more serious kidney problems.  They can be caused by urinary tract infections, polycystic kidney disease, kidney infections, blood clots, and/or bleeding in the kidneys.  
Hepatitis C is a disease that attacks the liver and can cause kidney disease.  

Symptoms include

Loss of appetite
Nausea
Fever
Fatigue
Vomiting
Dark colored urine
Grey colored stool
Joint pain
Yellow skin and eyes
While kidney diseases are at best unpleasant, and at worst, life-threatening, they can be avoided by drinking lots of water, eating a healthy low salt diet, and watching for any changes in health and urine over time.



What Happens When Kidneys Fail & Signs That Indicate It

Glomerulonephritis is a disease that is caused due to inflammation of the small filters that are present within the kidneys or glomeruli. Glomeruli eliminate the excess waste, electrolytes and fluids from the blood, discharged through urine. A glomerular disease can be either acute or chronic. If the condition arises without a combination of any other disease, it is termed as primary glomerulonephritis. Secondary glomerulonephritis is characterized by diabetes or lupus (an auto-immune disorder) being at the root of the disease. Prolonged or severe inflammation can take a toll on the kidneys.


Causes-


Nephrotic syndrome can be primary, being a disease specific to the kidneys, or it can be secondary, being a renal manifestation of a systemic general illness. In all cases, injury to glomeruli is an essential feature. Kidney diseases that affect tubules and interstitium, such as interstitial nephritis, will not cause nephrotic syndrome.


Primary causes of nephrotic syndrome include the following, in approximate order of frequency:
Minimal -change nephropathy
Focal glomerulosclerosis
Membranous nephropathy
Hereditary nephropathies


Secondary causes include the following, again in order of approximate frequency:
Diabetes mellitus
Lupus erythematosus
Viral infections (e.g., hepatitis B, hepatitis C, human immunodeficiency virus [HIV] )
Amyloidosis and paraproteinemias
Preeclampsia
Allo-antibodies from enzyme replacement therapy


Nephrotic- range proteinuria may occur in other kidney diseases, such as IgA nephropathy. In that common glomerular disease, one third of patients may have nephrotic- range proteinuria.


Nephrotic syndrome may occur in persons with sickle cell disease and evolve to renal failure. From a therapeutic perspective, nephrotic syndrome may be classified as steroid sensitive, steroid resistant, steroid dependent, or frequently relapsing.


Treatment-
Whether one is suffering from acute or chronic nephrotic glomerular , with symptoms moderate or severe, the treatment lies in treating high blood pressure and other underlying conditions of the disease.
Water pills help control sweating, thus increasing the fluid flushed from the kidneys.
Statins reduce cholesterol level.
Blood thinners such as anticoagulants lower the risk of blood clots.
Corticosteroids regulate the immune system and ease the inflammation that results from kidney disorders.
Incorporating certain lifestyle changes such as opting for lean proteins, cutting on the intake of fat in the diet and consuming lesser amounts of salt can treat inflammation and swelling.
For kidney failure, dialysis can come to the aid in eliminating excess fluids and regulating hypertension.
