Urinary Tract and Kidney Infections

Urinary tract infections (UTI) are a very common medical complication of pregnancy. Unless treated, UTI can cause serious problems in pregnancy. Normal urine is sterile. It contains fluids, salts, and waste products, but it is free of bacteria, viruses, and fungi. The tissues of the bladder are isolated from urine and toxic substances by a coating that discourages bacteria from attaching and growing on the bladder wall.

The main parts of the urinary tract are:

Pregnancy and urinary tract infections:

During pregnancy, there are normal changes in the function and anatomy of the urinary tract. These include kidney enlargement, and compression of the ureters and bladder by the growing uterus. During pregnancy, the bladder does not empty as well. The urine is not as acidic and it contains more sugars, protein, and hormones. All of these factors can contribute to an increased susceptibility to UTI.

Types of UTI in pregnancy include the following:

The most common organism that causes UTI is Escherichia coli (E. coli), a normal organism of the vagina and rectal area. Other organisms may also cause UTI, including group B streptococcus, and sexually transmitted gonorrhea and chlamydia.

In addition to a complete medical history and physical examination, diagnosis of UTI is made by urine testing and culture for bacteria. Most women are tested at the first prenatal visit and during pregnancy, if needed.

Treatment of UTI is important to prevent serious complications. Antibiotics may be administered. Women with pyelonephritis in pregnancy often need to be hospitalized to receive intravenous (IV) antibiotics.
