What Is Urine?

What Is Urine?

What Is Urine - Urine culture is a method of examination to detect the presence of bacteria in the urine, as a sign of a urinary tract infection. In addition to identifying the presence of bacteria, urine culture can also be used to determine the type of bacteria that cause disease.

Bacteria can enter the urinary tract into the urethra, both men and women. The bacteria that enter the urinary tract can grow and develop rapidly. Urinary tract diseases that not treated properly can be dangerous and cause complications, ranging from the spread of contagion to other parts of the body, to permanent kidney failure.

Indications for Urine Culture

A person can be recommended to undergo a urine culture check if he has a complaint of urinary tract infection. These complaints are:

  • Pain and burning sensation when urinating
  • Low back pain
  • Urine is cloudy and pungent
  • Frequently want to pee and cannot be detained
  • It feels that there is pressure on the lower part of the stomach
  • There is blood in the urine.
If the urinary tract infection that occurs is severe enough or has spread to the kidneys, the following symptoms can appear:
  • High fever
  • Shivering
  • Trembling
  • Nausea or vomiting.
In addition to sufferers of urinary tract infections, urine culture is also recommended to be carried out by pregnant women in the first trimester of pregnancy or on the first (prenatal) pregnancy visit. The aim is to detect the presence of bacteria in the urinary tract which can affect the health and development of the fetus.

Not all sufferers of urinary tract infections need to undergo urine culture checks but are immediately given medication only by looking at the symptoms and results of urine tests. Is often done in young women who have lower urinary tract infections but do not cause any complications.

Preparation of Urine Culture

Before urine culture does, the patient needs to tell the doctor about the medicines being consumed, including vitamins and supplements. The drug content and vitamins in urine can affect the results, making it inaccurate. Approaching, the time for sampling, it is recommended to hold urination until the time of sampling. 

Procedure for Taking Urine Culture Samples

The procedure for taking urine samples is quite simple. The patient is first required to wash his hands and clean his genitals, to avoid bacterial contamination from the outside. The male patient needs to clean the head of his penis, while the female patient must clean her vagina from front to back.

At the time of urination, patients do not directly hold urine in the container, but first, throw about half the urine that comes out first. After that, the patient can keep the remaining urine in the body in the sample container until it reaches the required amount. Then clean the genitals after completing the sampling, then wash your hands.

Taking urine samples can also be done through a catheter, which is a thin tube that inserted through the patient's urethra. The medical officer will take fresh urine from the patient and not take it from the urine shelter. In some instances, urine can be made through an excellent needle aspiration method. Needle aspiration through the needle does if the patient cannot excrete urine through the catheter or if the sample obtained from the previous sampling method is always contaminated.

Urine that has collected is then sent to the laboratory to be tested for the presence of bacteria causing the infection.

Procedure and Interpretation of Urine Culture Test Results

What Is Urine - Urine samples from patients will take to the laboratory for analysis. Urine samples will be cultured in a particular medium in the form of agar, then stored in a specific room of storage that has temperatures such as body temperature. If there are bacteria in the urine, it will grow in a few days. Keep in mind that on the surface of the penis and vagina, there are normal microorganisms that may carry in the sample.

From the results of the number of bacterial colonies that grow, as well as the symptoms that developed, the doctor will assess whether the patient has a urinary tract infection, and whether or not it is needed treatment. If you feel the results are doubtful, your doctor can recommend repeating the urine culture examination.

Various types of bacteria can cause urinary tract infections. However, the kind of bacteria that most often causes this infection is Escherichia coli, which usually found in the digestive tract. Other bacteria that can cause urinary tract infections are:

  • Proteus sp
  • Enterococcus sp
  • Klebsiella sp
  • Staphylococcus sp
  • Candida sp.
If you know the type of bacteria that grows, a resistance or vulnerability test will be carried out through the same sample.
