 National Cancer Institute - Bladder Cancer Treatment
Bladder cancer is a disease in which malignant (cancer) cells form in the tissues of the bladder.
When the bladder is emptied during urination, the urine goes from the bladder to the outside of the body through another tube called the urethra.
Cancer that begins in the transitional cells may spread through the lining of the bladder and invade the muscle wall of the bladder or spread to nearby organs and lymph nodes; this is called invasive bladder cancer.

 Neurogenic Bladder | aHealthyAdvantage   (Site not responding. Last check: 2007-10-20)
Normal bladder function is dependent on the nerves that sense the fullness of the bladder (sensory nerves) and on those that trigger the muscle movements that either empty it or retain urine (motor nerves).
An overactive neurogenic bladder is characterized by uncontrolled, frequent expulsion of urine from the bladder.
Neurogenic bladder is diagnosed by carefully recording fluid intake and urinary output and by measuring the quantity of urine remaining in the bladder after voiding (residual urine volume).

 Urinary bladder - Wikipedia, the free encyclopedia
The urinary bladder is normally capable of storing 1.1-1.3 liters of urine, but because it is made up of transitional epithelium it is able to stretch to volumes of even several liters.
The ureters enter the bladder diagonally from its dorsolateral floor in an area called the trigone.
The trigone is a triangular shaped area on the postero-inferior wall of the bladder.

 MedlinePlus Medical Encyclopedia: Bladder cancer
Bladder cancer is a malignant tumor growth within the bladder.
Bladder cancers usually arise from the transitional cells of the bladder (the cells lining the bladder).
Bladder cancers are classified or staged based on their aggressiveness and the degree that they are different from the surrounding bladder tissue.

 Bladder cancer | AHealthyMe.com
Bladder cancer is a disease in which the cells lining the urinary bladder lose the ability to regulate their growth and start dividing uncontrollably.
A change in bladder habits such as painful urination, increased frequency of urination and a feeling of needing to urinate but not being able to do so are some of the signs of possible bladder cancer.
If a person has had a history of bladder cancer, or has been exposed to cancer-causing chemicals, then he or she is considered to be at an increased risk of getting bladder cancer.

 Bladder Cancer - Overview, Types, Causes, Symptoms, Diagnosis - urologychannel
Urine is produced by the kidneys, carried to the bladder by the ureters, and discharged from the bladder through the urethra.
Bladder cancer usually originates in the bladder lining, which consists of a mucous layer of surface cells that expand and deflate (transitional epithelial cells), smooth muscle, and a fibrous layer.
The primary symptom of bladder cancer is blood in the urine (hematuria).

 Dr. Koop - Neurogenic Bladder- Health Encyclopedia and Reference
Neurogenic bladder is impaired bladder function resulting from damage to the nerves that govern the urinary tract.
Various nerves converge in the area of the bladder and serve to control the muscles of the urinary tract, which includes the sphincter muscles that normally form a tight ring around the urethra to hold urine back until it is voluntarily released.
Patients suffering from bladder paralysis can be taught to insert a catheter several times a day to drain the bladder completely and so prevent urine retention that may led to bladder stones and infection.

 AllRefer.com - swim bladder (Zoology: General) - Encyclopedia
The swim bladder, or air bladder, is located in the dorsal portion of the body cavity and is filled with gases.
When gas is added to the swim bladder, by diffusion through the blood vessels in the bladder walls, the fish becomes less dense overall; when gas is removed the fish becomes more dense.
In most fish the swim bladder has no connection to the digestive tract, but in some, such as the lungfish, there is a connecting tube leading to the pharynx, indicating that the organ may aid in respiration.

 Neurogenic Bladder
Or urine that stays too long may lead to an infection in the bladder or ureters, which are the tubes that carry urine from the kidney to the bladder.
If neurogenic bladder is suspected, the doctor may need to test both the nervous system (including the brain) and the bladder itself.
If the problem is urinary retention (the bladder does not know when to let go), it may be necessary to use a catheter to empty the bladder at regular times.

 BLADDER INFECTIONS
The reason girls are more prone to bladder infections than boys is the female urethra is much shorter, therefore the bacteria has less distance to travel into the bladder.
While it is true an uncircumcised male has a higher chance of bladder infections during the first year of life, this risk goes away after age one.
For older children who have had several bladder infections and you are very familiar with the symptoms, your doctor may elect to simply treat with antibiotics instead of going through the trouble of checking a urine sample.

 IC Endo
Bladder involvement is found in approximately every seventh to eighth case of diagnosed Endometriosis.
Endometriosis of the bladder may initially present with such a simple sign as painful urination, sometimes being mistaken for a urinary tract infection.
Other theories include the belief that bacteria may be present in the bladder cells, but remains undetectable through routine cultures; that certain substances in urine may be irritating to IC sufferers; and that the condition, like Endometriosis, may be hereditary.

Most Bladder Infections are caused by the bacteria called Escherichia coli that contain tiny projections that glue it to the lining of the urinary tract.
Bladder infections have long baffled doctors -- and agonized patients -- with their resiliency.
Once there, the bugs use sticky, hair-like structures called pili to cling to the walls of the urethra and bladder, without this strong adhesion the bacteria can't cling and colonize because the environment is constantly flushed with urine.

 National MS Society | Sourcebook: Bladder Dysfunction   (Site not responding. Last check: 2007-10-20)
Bladder dysfunction occurs when MS lesions block or delay transmission of nerve signals in areas of the central nervous system that control the bladder and urinary sphincter.
The sphincter is the muscle surrounding the opening of the bladder, which controls the storage and outflow of urine.
These symptoms may be caused by a "spastic" bladder that is unable to hold the normal amount of urine, or by a bladder that does not empty properly, and thus always retains some urine in it.

When food containing fat reaches the small intestine, the hormone cholecystokinin is produced by cells in the intestinal wall and carried to the gall bladder via the bloodstream.
A valve, which opens only when food is present in the intestine, allows bile to flow from the common bile duct into the duodenum where it functions in the process of fat digestion.
They can cause inflammation of the gall bladder, a disorder that produces symptoms similar to those of indigestion, especially after a fatty meal is consumed.

 Overactive Bladder: Overview, Causes, & Symptoms - urologychannel
In people with an overactive bladder (OAB), the layered, smooth muscle that surrounds the bladder (detrusor muscle) contracts spastically, sometimes without a known cause, which results in sustained, high bladder pressure and the urgent need to urinate (called urgency).
Normally, the detrusor muscle contracts and relaxes in response to the volume of urine in the bladder and the initiation of urination.
Pressure in the bladder increases and the detrusor muscle remains contracted until the bladder empties.
