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?

You're said to suffer from the problem of acute kidney failure if your kidneys suddenly stop working and lose their ability to eliminate waste materials including excess fluids and salts from the blood. The condition usually develops quickly over a few days or even a few hours. When this happens, waste materials accumulate in your blood, disrupting the chemical balance of your bloodstream.

So, what causes this problem?

Acute kidney failure can occur because of any one of these reasons:

1. A drop or slowdown of blood flow to the kidneys - Adequate blood circulation to the kidneys is of great importance as without it the kidneys may end malfunctioning. If blood flow to the kidney is hampered, a part of or the entire kidney may die. You may suffer from acute kidney failure if blood flow to the kidneys gets impaired due to conditions like

Heavy blood loss
Sepsis (body's inflammatory reaction to an infection, which can bring about organ failure, tissue damage, and death)
Injury
Use of certain drugs
Dehydration
Burns
Heart disease
2. Urinary obstructions - A sudden blockage that hampers your kidney's ability to eliminate urine can also bring about acute kidney failure. When this happens, it leads to a build up of toxins in the body, causing an overload of the kidneys. Conditions that bring about this urinary obstruction include:

Cervical cancer
Colon cancer
Bladder cancer
Kidney stones
Enlarged prostate
Prostate cancer
3. Disease within the kidneys - Even instances of clotting within the blood vessels of the kidneys can lead to acute kidney failure. This is because if the movement of blood cells within the blood vessels gets hampered, kidneys are not able to filter out toxins from the body. The conditions and diseases that may cause clotting, and subsequently damage to the kidneys include:

Scleroderma (an autoimmune disease that affects connective tissues and skin)
Build-up of cholesterol deposits
Glomerulonephritis (an inflammatory condition of the kidney's ball-shaped structures called glomeruli)
Hemolytic uremic syndrome (a condition that occurs due to untimely death of red blood cells)
Lupus (a disorder of the body's immune system that brings about damage to the body's own organs and tissues)

A kidney transplant is a procedure that employs an operation to transplant properly functioning kidney in the body. The main job of the kidneys is to remove the excess waste from a person s body with the help of a filtration process. When the kidneys stop filtering the toxins properly, they become diseased as harmful waste products and toxins begin to accumulate in the body. Following this, the patient has to go through treatment measures like dialysis or kidney transplant.

Read on to know the five things you should keep in mind about a kidney transplant.

Treatment: Transplant is one of the best ways to treat chronic kidney disease stage-V, until unless it is contraindicated. Life becomes near normal after transplant, though there is a possibility of rejection of transplant kidney. Patient has to take immunosuppressive medication life long. 
Medication: Medications are mainly for:
To prevent rejection: Patient takes immunosuppressive medications life long. 
Prevention of infection: Patient has to take care all the measures to prevent infections as they are more prone to infections. 
Other medication: To control diabetes, HTN etc. 
Family Only: The donors are from family or emotionally related or cadavers (after brain death). HLA-matched donors are better because of less chances of rejections and first reduction of immunosuppressive. 
Doing Your Part: Once transplant is done - patient becomes normal and he/she lives a normal life. However, they have to take regular medications and to protect themselves from various infection. 
End Stage Renal Diseases: These diseases includes diabetes mellitus, HTN, polycystic kidney disease, chronic glomerulonephritis or interstitial nephritis etc.
Consult your Nephrologist before going for renal transplant for detailed check up or line of action.

Kidney Transplant - 5 Things About it !

Blood in urine, medically known as Hematuria is not usually a cause of concern, but it can translate into an adverse condition if left unevaluated. The kidneys and other structures in the urinary tracts such as urethra (tube connecting the bladder to the outer part of the body); bladder (that stores the urine) and ureters (tube joining the bladder to the kidney) are the sources of blood flow to the urine. Hematuria can be accompanied by symptoms such as discharge of tea-colored, brownish-red or pink colored urine due to the presence of red blood cells, traces of which can only be detected under the microscope.

Underlying causes behind this disorder might be

Urinary tract infections is where the bacteria enter the body through the urethra and begin to proliferate in the bladder.
Kidney infections (pyelonephritis) is when bacteria infiltrate into the kidneys from the bloodstream or travel up from the uterus to the kidneys.
A kidney or a bladder stone is marked by the minerals in the concentrated urine precipitating out and molding into crystals that deposit on the bladder or kidney walls.
Enlarged prostate is a condition in which the prostate gland, that is situated just below the bladder surrounding the upper part of the urethra, starts growing as males head towards their middle age.
Kidney disease such as glomerulonephritis causes swelling of the kidneys, thus disrupting the filtering system.
Bladder, kidney and prostate cancer are also possible causes.
Hereditary disorders such as sickle cell anemia (a hereditary disease of the red blood cells in the hemoglobin) can also pose as a cause behind this disorder.
Kidney injury as a result of heavy blows, accidents or injuries sustained while playing a spot can also contribute to this condition.
Medications such as penicillin or the anti-cancer drug  cyclophosphamide 
Strenuous physical exercises like intense workout or running may also result in Hematuria.
Treatments
There is no fixed cure for Hematuria; instead the doctor would work on treating the repressed conditions behind the symptoms, such as prescribing antibiotics to heal the urinary tract infection or a medicine to shrink and normalize the enlarged prostate or administer a shock wave therapy to destroy the kidney or bladder stones.

Blood in Urine - 10 Causes Behind It

The kidneys are the main excretory organs and remove all toxins and wastes from the body in a liquid medium, the urine. The urine is normally straw coloured as there are filters which do not allow blood to enter the kidneys. However, due to various reasons, when there is a disease in the urinary tract, red blood cells can escape into the urine. The urine then assumes a pinkish tinge; the exact colour would depend on the amount of blood leaked. While the thought of pinkish urine is scary, it becomes a bigger concern when seen in children. Read on to know a little more about the types, causes, and ways to manage this condition. 

Types: 

Microscopic: When there is blood visible only through a microscope. This is quite common in children, and unless there is no accompanying kidney disease, it does not pose a problem when found occasionally. 
Gross: It is when the color of the urine changes to a pinkish tinge. This is of concern and requires immediate attention. 
Causes: 

There are various reasons and some of them are listed below 

Inherited causes: Conditions like sickle cell disease, polycystic kidney disease, Kidney stones and inherited nephritis. 
Structural causes: Cysts in the kidneys can cause hematuria 
Trauma: An injury (to the abdominal area) during sports should be ruled out, which could have damaged the problem 
Infections: Infections along the entire urinary tract right from glomerulonephritis to kidneys to bladder can cause blood in the urine 5.   Imbalances in minerals: High levels of serum calcium, which puts them at a higher risk of developing kidney stones later. Dietary calcium should be reduced. These children also could have a history of stones in the family. 
Idiopathic: When the cause of the hematuria is not known, it is termed idiopathic. 
Associated issues/Diagnosis: 

Hematuria is an indication or a symptom of an underlying medical condition (be it infection or trauma) and the underlying cause always needs complete evaluation. Accompanying symptoms can help narrow down the diagnosis. If any inherited cause is suspected, presence of hematuria should always be assessed in parents and grandparents. 

Check for history of trauma 
Known prior kidney disease 
Symptoms of infection 

Family medical history 
Urine tests to analyse its composition 
Urine culture, MRI, CT scanning, or biopsy may be required in more serious cases. 
When to worry? 

Associated proteinuria 
Microscopic hematuria which is persistent 
Kids with high blood pressure 
Kids with other existing kidney diseases 
Management: 

In most cases, no specific treatment for hematuria is required as the condition subsides after the underlying problem is addressed. For instance, once the infection clears, the hematuria also clears. Follow-up urine tests may be required to confirm that it is cleared. Blood in urine must always be evaluated by pediatric nephrologist as its causes range from very mild disease to rapidly evolving kidney failure, which may occur over days to weeks.

Blood In Urine In Kids - Know The Reasons Behind It!

Infection caused in the kidneys, bladder, urethra or the ureters is known as urinary tract infection. According to doctors, women are generally more at risk of suffering from this condition than men. Some of the causes which contribute to the development of this infection are:

1. Invasion of bacteria: like any other infection, one of the causes of urinary tract infection is the invasion of the bacteria escherichia coli in the bladder. This type of bacteria is most commonly found in the gastrointestinal tract and is most often held responsible for urinary tract infection.

2. Spreading of the bacteria from anus to urethra: the spread of the gastrointestinal bacteria from the anus to the urethra leads to the infection of the urethra thereby causing urinary tract infection. 

Some of the symptoms of urinary tract infection are

1. A nagging urge to urinate: one of the most predominant symptoms of urinary tract infection is a persistent, nagging urge to urinate. You would know your urinary tract is infected when you feel the urgency to urinate extremely frequently.

2. There is a burning sensation when you urinate: the symptoms of urinary infection are extremely visible and are felt intensely by the one suffering from it. If you feel a burning sensation while urinating, chances are extremely high that you are suffering from urinary tract infection.

3. Red colored urine: sometimes your urine may contain perceptible amount of blood in them. In most cases, presence of blood in urine is a definite sign of urinary tract infection.

4. Foul smelled urine: an internal infection in the urinary tract manifests itself in different ways. One of the chief symptoms of this infection is discharging foul smelling urine.

5. Pain in the pelvic area: women who suffer from urinary tract infection experience excruciating pain near the pelvic area, sometimes extending to the pubic bone.
