A urinary tract infection, or UTI, is an infection that can happen anywhere along the urinary tract -- the kidneys, the ureters (the tubes that take urine from each kidney to the bladder), the bladder, or the urethra (the tube that empties urine from the bladder to the outside). Therefore, a bladder infection is simply an infection mostly present in the bladder itself as opposed to the kidneys or urethra.

Home remedy for bladder infection
Cranberry -- The use of cranberry among individuals to prevent or treat bladder infection is a common practice. The accumulating evidence suggests that cranberry may relieve symptoms associated with bladder infection and may reduce the need for antibiotics. American cranberry (Vaccinium macrocarpon) is one of only three species of fruit native to North America. The other species are blueberry (Vaccinium angustifolia) and bilberry (Vaccinium myrtillus). Cranberry typically grows in bogs and is a member of the same family as blueberry and bilberry. The ripe fruit was used medicinally by Native Americans for the treatment of bladder and kidney ailments. Pilgrims called the fruit "craneberry" because the stem and flower resembled the head, neck, and beak of a crane. Therapeutic applications of cranberries documented during the 17th century included the relief of blood disorders, stomach ailments, liver problems, vomiting, appetite loss, scurvy, and cancer. Before the advent of antibiotics, cranberry continued to be a popular treatment for urinary tract infections (UTIs). The current proposed mechanism of action focuses primarily on cranberry's ability to prevent bacterial binding to host cell surface membranes. In vitro studies have observed potent inhibition of bacterial adherence of Escherichia coli4 and other gram-negative uropathogens.

Bladder infection symptom
Bladder infection usually produces a frequent, urgent need to urinate and a burning or painful sensation while urinating. The urgent need to urinate may cause an uncontrollable loss of urine (incontinence), especially in older people. Fever is rarely present. Pain is usually felt above the pubic bone and often in the lower back as well. Frequent urination during the night (nocturia) is another symptom. The urine is often cloudy and contains visible blood in about 30% of people. Bladder infection symptoms may disappear without treatment.

Cause of bladder infection
A bladder infection is common in women, particularly during the reproductive years. Some women have recurring episodes of bladder infection. There are a number of reasons for this—the short length of the urethra and the closeness of the urethra to the vagina and anus, where bacteria are commonly found. Sexual intercourse can contribute, too, because the motion can cause slight injuries to the urethra and a tendency for bacteria to ascend to the bladder. Pregnant women are especially likely to develop bladder infection because the pregnancy itself can interfere with emptying of the bladder. Use of a diaphragm increases the risk of developing a bladder infection, possibly because spermicide used with the diaphragm suppresses the normal vaginal bacteria and allows bacteria that cause cystitis to flourish in the vagina.

Bladder Stone - World Record
October 2006 - Israeli doctors removed a grapefruit-sized stone from the bladder of an Israeli woman after she left it untreated for years. The stone, removed in its entirety, had a diameter of 13 centimeters (5.1 inches) and weighed almost 1 kilograms (2.2 lbs), doctors who treated the 48-year-old woman at the Western Galilee Hospital in northern Israel said. "When I saw the stone, I was stunned," patient Moneera Khalil said in a statement released by the hospital. "I could not believe such a thing was inside my body. I am happy everything ended well and that the pain is gone." The Guinness Book of World Records lists a bladder stone weighing 260 grams (0.6 lb) with a diameter of 7 cm (2.75 inches), taken from a man in Yemen in 1998, as the largest ever removed. Haim Farhadian, the physician who removed Khalil's stone, said the woman had been hospitalized three years ago after suffering similar pains but had refused treatment. Dehydration can often cause dissolved minerals in a person's urine to form masses inside their kidneys, ureters or bladder. Such "stones" causes abdominal pain by obstructing urine flow.
