Urinary Tract Infections in Children: NIDDK (Excerpt)

Some of your child's urine will be collected and examined. The way urine is collected may depend on how old your child is. The health care provider may place a plastic collection bag over your child's genital area (sealed to the skin with an adhesive strip) if the child is not yet toilet trained. An older child may be asked to urinate into a container. The sample needs to come as directly into the container as possible to avoid picking up bacteria from the skin or rectal area. A doctor or nurse may need to pass a small tube into the urethra. Urine will drain directly from the bladder into a clean container through this tube (called a catheter). Sometimes the best way to get the urine is by placing a needle directly into the bladder through the skin of the lower abdomen. Getting urine through the tube or needle will make sure that the urine collected is pure.

Some of the urine will be examined under a microscope. If an infection is present, bacteria and sometimes pus will be in the urine. If the bacteria from the sample are hard to see at first, the health care provider may place the sample in a tube or dish with a substance that encourages any bacteria present to grow. Once the germs have multiplied, they can then be identified and tested to see which medications will provide the most effective treatment. The process of growing bacteria in the laboratory is known as performing a culture and often takes a day or more to complete.

The reliability of the culture depends on how long the urine stands before the culture is started. If you collect your child's urine at home, it should be refrigerated as soon as collected and the container should be transported in a plastic bag filled with ice.

Urinary Tract Infections in Children: NIDDK (Excerpt)

Once the infection has cleared, additional tests may be recommended to check for abnormalities in the urinary tract. Repeated infections in abnormal urinary tracts may cause kidney damage. The kinds of tests ordered will depend on your child and the type of urinary infection. Because no single test can tell everything about the urinary tract that might be important to know, more than one of the following tests may be needed:

  • Kidney and bladder ultrasound: A test that examines the kidney and bladder using sound waves. This test shows shadows of the kidney and bladder that may point out certain abnormalities; this test cannot reveal all important urinary abnormalities. It also cannot measure how well a kidney works.

  • Voiding cystourethrogram (VCUG): A test that examines the urethra and bladder while the bladder fills and empties. A liquid that can be seen on x-rays is placed into the bladder through a catheter. The bladder is filled until the child urinates. This test can reveal abnormalities of the inside of the urethra and bladder. The test can also determine whether the flow of urine is normal when the bladder empties.

  • Intravenous pyelogram: A test that examines the whole urinary tract. A liquid that can be seen on x-rays is injected into a vein. The substance travels into the kidneys and bladder, revealing possible obstructions.

  • Nuclear scans: A number of tests using radioactive materials that are usually injected into a vein to show how well the kidneys work, the shape of the kidneys, and whether urine empties from the kidneys in a normal way. The many kinds of nuclear scans each give different information about the kidneys and bladder. Nuclear scans expose a child to no more radiation than he or she would receive from a conventional x-ray. At times, it can even be less.
