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?

Bladder cancer is characterized by irregular growth of abnormal tissue (tumor) on the lining of the bladder. This type of cancer may spread to the surrounding tissues or other body parts as well.

What are the causes?

Bladder cancer can be caused by environment-related factors and smoking. In fact, smoking tobacco is one of the major causes of bladder cancer around the world. The chemicals present in tobacco can irritate the bladder lining which ultimately leads to bladder cancer. It may also be caused by continuous exposure to chemicals such as dyes or leather dust and radiation. These chemicals tend to cause unusual changes in the cells of the bladder lining and causes cancer in the bladder.

It can also be caused by modifications in the dna in the cells of the bladder which may impair the functioning of the cells in the body. This can cause mutations in the bladder resulting in cancer.

What are the symptoms?

1. Presence of blood in the urine, often painless

2. Feeling of pain while passing urine

3. Back pain

4. Excessive urination

5. Infections in the urinary tract

6. Lower leg swelling

7. Pain in the bones, especially in the pelvic area

8. Weight loss

Treatment options

Treatments for bladder cancer depend on the stage of the cancer. The various treatment choices are:

Surgery - In some cases, these cancers are surgically removed by a surgeon. A type of surgery used is transurethral resection of bladder tumor (turbt) where the cancer cells are destroyed with laser by passing a thin fiber into the bladder.

Chemotherapy - In this method, medications are used to target and destroy cancer cells.

Radiation therapy - Radiation therapy uses rays such as x-ray or uv rays to destroy cancer cells in the body

Immunotherapy - This treatment boosts the immune system of the body so that it attacks the cancerous cells in the bladder.

Causes And Symptoms of Bladder Cancer

A problem pertaining to the storage function of the bladder that results in bouts of sudden, often uncontrollable urge to urinate is referred to as an overactive bladder. This condition which is marked by unconditioned or involuntary loss of urine can sometimes be quite difficult to stop. People who experience such a condition often feel humiliated and as such tend to limit their social and work life. Despite such, only a few are conscious that a brief evaluation can help them manage and overcome an overactive bladder.

Mechanism of urination

During urination, the urine proceeds from the bladder and flows into the urethra which is located at the tip of the penis in men and above the vagina in women. As the bladder fills, the nerve signals in the brain prompts urination by coordinating the relaxation and contraction of the urinary sphincter muscles.

Causes and symptoms of an overactive bladder

Primarily caused due to involuntary contraction and relaxation of sphincter muscles, several conditions can lead to overactive bladder. 

Some of them are: 
1. Parkinson's disease, alzheimer's and other neurological disorders
2. Poor kidney function due to diabetes
3. Medications that lead to increased production of urine
4. Bladder abnormalities like tumors or stones
5. Constipation
6. Excessive consumption of caffeine or alcohol

Some of the common signs of an overactive bladder are:
1. Bouts of sudden, uncontrollable urge to urinate
2. Awakening at night frequently to urinate
3. Urinating more than eight times a day

Risks
The risk of an overactive bladder gradually increases with age. Conditions, such as diabetes and an enlarged prostate results in the increased likelihood of an overactive bladder. People who have previously faced strokes and heart attacks experience cognitive decline, which often times lead to the development of an overactive bladder.

Urinary incontinence as well as a host of associated factors can be detrimental to your life. Emotional distress, interrupted sleep cycles and depression are some of the observed complications of this condition.

Thus if you experience or entertain suspicion of an overactive bladder, you should consider visiting a general physician who might refer you to a specialist, if need be.

All about Overactive Bladder

An overactive bladder is a condition that is characterized by a problem in the bladder storage function; a problem that eggs one on to urinate frequently. This condition can cause problems in your social and work life. You may isolate yourself from others and feel embarrassed about the situation.

Symptoms
If you have an overactive bladder, you may exhibit symptoms of frequent urination, involuntary leakage of urine and frequent urge to urinate. These symptoms might disrupt your daily life; so it is important to seek advice from a medical practitioner.

Causes
To better understand what causes an overactive bladder, you need to know how the urination process works. Urine is produced by the kidneys, which flows to the bladder. During urination, the urine is excreted from an opening in the bladder and flows out via the urethra. As the kidneys secrete urine, the bladder starts to fill up. During this stage, nerve signals are sent to the brain; signals that trigger your body to urinate. The bladder muscles tighten that pushes the urine out of the body.

An overactive bladder results from the involuntarily contraction of the bladder, which might happen even if the content of urine in the bladder is low. These contractions create the urge to urinate. The various causes of an overactive bladder are:

Excessive fluid intake, if your fluid intake is high, then you may have the tendency to urinate frequently.
Presence of tumors or stones in the bladder can make the bladder overactive as well.
Excessive alcohol or caffeine consumption has the same effect as an excessive intake of fluids has.
Urinary tract infections may interfere with the entire process of urination, thus causing your bladder to swell up and become overactive.
Other diseases and conditions such as constipation and an enlarged prostate can hamper bladder functioning.
Treatment
There are multiple approaches to treat an overactive bladder; your doctor may use one or a combination of multiple methods.

Medications: Medications such as Trospium and Tolterodine help in relaxing the bladder. These medications help treat symptoms of frequent urination.
Bladder injections: Botox is a protein that is injected into the bladder that causes partial paralysis of the bladder muscles. This helps in treating the constant urge to urinate. However, its effects are temporary as they last for 6-9 months.
Lifestyle modifications: Certain lifestyle modifications such as incorporating exercises to strengthen the pelvic muscles, maintaining optimal weight levels and bladder training to control its functioning can help with managing an overactive bladder.
Surgery: If the other treatments do not produce the desired results, then surgery is usually recommended. The aim of the surgery is to enhance the storage capacity of the bladder and reduce bladder pressure.

Frequent Urination - Is It A Symptom of An Overactive Bladder?

The kidneys make urine, which is a fluid through which wastes from the body including urea are eliminated from the body. There are two kidneys on the right and left side, which make urine, and pass it down to the bladder through tubes known as ureter. The bladder acts as a reservoir of the urine that is formed in the kidneys. It is stored temporarily there before being excreted out of the body through the urethra. The urinary bladder is a highly muscular organ and has a rich connective tissue. 

Interstitial cystitis (IC) or painful bladder syndrome (PBS) is a very common condition, which affects females more than males. While the exact etiology is not known, it could be age-related and also lifestyle related. People who are used to controlling the urge to pass urine are highly likely to develop this condition. The simple logic is that there is additional pressure on the bladder from the urine that is contained for longer period of time. As such, the muscular wall stretches and begins to feel stressed.

When this habit continues over a period of time, the bladder wall may become irritated or inflamed or even scarred in severe cases. There is no role of bacteria in this condition, and antibiotics are of no help in managing this condition (though the name cystitis usually indicates infection).

The following symptoms are seen as a result of this constant irritation and inflammation.

One may suffer from pain and pressure in the bladder as it continues to collect more and more urine.
This pressure in the bladder also puts pressure on the surrounding tissues in the abdomen including the pelvis, urethra, abdominal organs, uterus, etc.
Women may experience pain in the vaginal tract including vulva and behind the vagina.
Men may experience pain in the area of the scrotum, testicles, prostate, and penis.
There is an increased urge to urinate, which may be as much as 9 to 10 times a day. As the condition progresses, there could be more visits, as many as 40 to 50 visits a day.
This tendency and urge to urinate increases during nighttime.
For women, this urge to urinate and other symptoms including pain are worse during menstruation.
There could be pain during intercourse for both men and women.
There could be pain even otherwise, which can range from a mild dull ache to a piercing pain.
At a structural level, this constant pressure leads to pinpoint bleeding (glomerulations) and sometimes even ulcers in the bladder wall.
There is no definitive treatment for IC or PBS. However, bladder distention and instillation are proven methods of increasing bladder capacity, which therefore helps in relieving symptoms.

Painful Bladder Syndrome - Know The Signs!

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.
