Urinary tract infections
Urinary tract infections: Introduction
Urinary tract infections are common infections of the urinary tract, which consists of the kidneys, ureters, bladder, urethra and the prostate gland. Urinary tract infections are the result of an invasion of bacteria or other microorganisms into the urinary tract.
Normally, urine and all of the organs and structures of the urinary tract are sterile and contain no microorganisms. However, infectious microorganisms can get into the urinary tract from outside the body through the urethra and cause urinary tract infections. Infectious microorganisms can also travel through the bloodstream from other parts of the body to cause urinary tract infections.
Urinary tract infections include bladder infection, bacterial prostatitis (urinary tract infection of the prostate gland) and pyelonephritis, a urinary tract infection of the kidney.
Symptoms of urinary tract infections can include frequent urination and bloody urine. Urinary tract infections can lead to potentially serious, even life-threatening complications in some people. For more information on complications and symptoms, refer to symptoms of urinary tract infections.
Urinary tract infections occur most commonly in women, because the urethra in women is shorter than a man's. This makes it easier for microorganisms to enter the female urinary tract and cause a urinary tract infection. Women who are sexually active, who use diaphragms for birth control, and/or are past menopause are at an increased risk for urinary tract infections.
Certain other populations are also at a higher risk for developing urinary tract infections. They include older adults and the elderly and people with a history of kidney stones, kidney disease, or chronic conditions that affect the immune system, such as HIV/AIDS and diabetes. People who have an indwelling catheter in their bladder are also at risk.
Making a diagnosis of a urinary tract infection begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination. It also includes performing a urinalysis test, which checks for the presence of pus, white blood cells, and bacteria in the urine, which point to a urinary tract infection. A urine culture and sensitivity is usually performed to find the exact microorganism that is causing the infection and to determine the most effective antibiotic to treat it.
Imaging tests, such as ultrasound, CT, nuclear scan, or voiding cystourethrogram may also be ordered to evaluate the functioning of the urinary tract.
A diagnosis of a urinary tract infection can easily be missed or delayed in the elderly. This is because some symptoms, such as fatigue and weakness, may not be noticed or might be associated with aging. For information on misdiagnosis, refer to misdiagnosis of urinary tract infections.
Mild urinary tract infections, such as a bladder infection, that are not accompanied with complications, such as pyelonephritis, are generally treated with oral antibiotic medications. People are also encouraged to drink plenty of water to help flush bacteria out of the bladder. The prognosis and the chance for a cure without complications are good for people who are generally healthy.
More serious infections, such as pyelonephritis, and urinary tract infections in people with HIV/AIDS or in the elderly, generally require hospitalization, especially if there are complications, such as sepsis. For more information on treatment, refer to treatment of urinary tract infections. ...more »
