What is a urinary infection?
It is commonly known as a urinary tract infection , but it can occur anywhere in the urinary system (kidneys, ureters, bladder and urethra) although it is most common in the lower urinary tract (bladder and urethra).
Women are more likely to have them than men because in women, the urethra is shorter and is closer to the anus
Causes
Urinary tract infections (UTIs) usually occur when bacteria enter the urinary tract through the urethra and begin to multiply in the bladder. Although the urinary system is designed to prevent these microscopic invaders from entering, these defenses sometimes fail. Doctors typically treat UTIs with antibiotics.
Symptom
- Cloudy or bloody urine that may have a strong or foul-smelling (smelly) odor.
- Low fever in some people.
- Pain or burning when urinating
- Pressure or cramps in the lower abdomen or lower back.
- Strong urge to urinate frequently, even shortly after you have emptied your bladder
A urinary tract infection limited to the bladder can be painful and bothersome. However, it can have serious consequences if it spreads to the kidneys.
Laboratory diagnostics
The following laboratory tests are performed to diagnose a urinary tract infection :
- Systematic analysis of a urine sample. We evaluate the levels of white and red blood cells as well as the presence of bacteria among other parameters.
- Culture of the bacteria of the urinary tract (UROCULTIVO). After systematic analysis of a urine sample, a culture is sometimes done. It reveals which bacteria are causing the infection and the most effective antibiotics against them.
