Our urinary system consists of the kidneys, ureters, bladder, and urethra. The most important parts in the system are the kidneys, which remove liquid waste from the blood in the form of urine and maintain a balance of salts and other substances in the blood. The kidneys also produce a hormone that aids the formation of red blood cells.

Ureters are narrow tubes that carry urine from the kidneys to the bladder, which is located in the lower abdomen. Urine is stored in the bladder and excreted through the urethra. The amount of urine passed by an average adult varies, depending on the fluids and foods he may have consumed.

Bladder infection is a bacterial infection that affects any part of the urinary tract. It is also commonly called urinary tract infection (UTI) or cystitis. Our urine contains a variety of fluids, salts and waste but is free from bacteria. Whenever bacteria gets into the bladder and starts multiplying in the urine, it causes a bladder infection. Bladder infections are common health problems affecting millions of people each year; only respiratory infections occur more often. Women are more prone to bladder infections than men, and one woman in five develops a bladder infection during her lifetime.

Bladder infections are quickly and easily treated, although they may cause a lot of discomfort. It is important that all bladder infections are treated at once, as they may sometime develop into a more serious kidney infection if left untreated. Bladder infections cannot be passed on from others, though sexual intercourse may cause bacteria to travel to the urinary tract in females, causing the infection.
