Urinary incontinence can be defined as the involuntary loss of urine. The urinary bladder, which stores urine until the patient voluntary empties its content, is a reservoir in the lower abdomen whose walls are a muscle that is supplied with nerve fibers. When the patient desires to empty their bladder, this muscle contracts forcing the urine out of the exit tube. There is a circular muscle surrounding its exit tube called the urinary sphincter. The muscular sphincter opens to allow for emptying of the urine, remaining closed most of the time to keep the urine stored in the bladder. Urinary incontinence is a common problem, perhaps more common in women than men, and may be temporary or chronic. Temporary urinary incontinence is loss of urine caused by another condition and disappears when the causative disease is no longer present.

E. coli is generally a harmless microorganism originating in the intestines. If it spreads to the vaginal opening, it may invade and colonize the bladder, causing an infection. The spread of E. coli to the vaginal opening most commonly occurs when women or girls wipe themselves from back to front after urinating, or after sexual activity. Staphylococcus saprophyticus accounts for 5 - 15% of UTIs, mostly in younger women. Klebsiella , Enterococci bacteria, and Proteus mirabilis account for most of remaining bacterial organisms that cause UTIs. They are generally found in UTIs in older women. Rare bacterial causes of UTIs include ureaplasma urealyticum and Mycoplasma hominis , which are typically harmless organisms. Organisms in Severe or Complicated Infections The bacteria that cause kidney infections ( pyelonephritis ) are general...
