Urinary tract infections (UTIs) are among the most common bacterial infections, affecting millions of people each year, especially women. Although they are often not serious, if not treated in time, they can lead to serious complications. This blog provides detailed information about the causes, symptoms, prevention and treatment of urinary tract infections.
What are urinary tract infections?
Urinary tract infections occur when bacteria enter the urinary tract, which includes the kidneys, ureters, bladder, and urethra. Most infections affect the lower urinary tract, that is, the bladder and urethra.
In more severe cases, the infection can spread to the kidneys, causing pyelonephritis, a very dangerous condition.
The most common causes of urinary tract infections
Urinary tract infections are caused primarily by Escherichia coli (E. coli) bacteria, which normally live in the intestines. They can be introduced into the urinary tract during sexual intercourse, after wiping in the wrong direction (from back to front), or due to poor hygiene.
Other factors include:
- Pregnancy
- Menopause
- dIABETES
- The use of catheters
- Structural abnormalities of the urinary tract
- Weakened immunity
Symptoms of urinary tract infections
The most common symptoms of urinary tract infections include:
- Burning during urination
- Frequent need to urinate
- Urinating in small amounts, but with a feeling of urgency
- Urine with a strong odor or cloudy color
- Lower abdominal pain
If the infection has spread to the kidneys, symptoms such as:
- High temperature
- Fever and chills
- Pain in the back or side of the lower back
- Nausea and vomiting
How are UTIs diagnosed?
Diagnosis of urinary tract infections is usually made by testing the urine for the presence of bacteria, white blood cells, or red blood cells. The urine sample must be collected carefully.
In some cases, a urine culture may be required to identify the type of bacteria and determine the most appropriate antibiotic for treatment.
Laboratory examinations include:
- Urinalysis: Shows the presence of leukocytes, nitrites, and other cells that signal infection.
- Urine culture: Important for identifying the microorganism and antibiotic sensitivity.
- Urinary sediment test: Analyzes elements in urine at a microscopic level.
If infections are recurrent or complications are suspected, the doctor may request advanced tests such as:
- Renal and bladder ultrasound: To detect obstructions or stones in the urinary tract.
- Computed tomography (CT): Provides a detailed view of urinary structures.
- Cystoscopy: Internal examination of the bladder through a flexible tube to identify abnormalities.
Types of urinary tract infections
Urinary tract infections are divided according to location:
Cystitis: Bladder infection, the most common, presents with burning during urination and a feeling of pressure in the lower abdomen.
Urethritis: Urethral infection is often associated with sexually transmitted diseases.
Pyelonephritis: Kidney infection, which requires urgent treatment due to the risk of systemic spread.
| Type of infection | Location | Main symptoms | The main risk |
| Cystitis | bladder | Burning, frequent urination, abdominal pressure | Spread to the kidneys |
| Urethritis | Urethra | Burning, urethral discharge, discomfort during urination | Link to sexually transmitted diseases |
| Pyelonephritis | Kidneys | Fever, back pain, nausea | Disseminated infection, sepsis |
How are urinary tract infections treated?
The main treatment is the use of antibiotics prescribed by a doctor, usually for a period of 3 to 7 days. It is important for the patient to complete the entire course of treatment even if symptoms disappear earlier.
In addition to medications, it is recommended:
- Drinking plenty of fluids to flush out bacteria
- Use of analgesics for pain relief
- Sufficient rest
In cases of kidney infections, hospital treatment with intravenous antibiotics may be necessary. In chronic or recurrent cases, the doctor may recommend long-term therapy or follow-up with periodic check-ups.
Prevention of urinary tract infections
Preventing urinary tract infections is essential to avoid their recurrence and protect the health of the urinary tract. Using simple methods and lifestyle changes can have a significant impact.
Drink plenty of water throughout the day to help flush bacteria from your urinary tract. Urinating immediately after sex is recommended to avoid introducing bacteria into your urethra. Wiping from front to back after using the toilet helps prevent the transfer of bacteria from the anus to your urinary tract.
Use cotton underwear and avoid tight clothing that can create a warm, moist environment suitable for bacteria to grow. Avoid using harsh soaps, intimate gels, or deodorants in the genital area, as they can irritate the urethra and alter the natural bacterial flora.
Eating foods that improve urinary health, such as cranberries, helps prevent bacteria from sticking to the bladder walls. Some studies suggest that D-mannose supplements or vaginal probiotics may be beneficial for women with recurrent infections.
Good personal hygiene, regular urination, and avoiding the use of antibiotics without a doctor's prescription are extremely important.
When should you see a doctor?
If you have symptoms of a urinary tract infection that last more than a day or two, or if your symptoms worsen, it is essential to consult a doctor. Pregnant women, the elderly, and people with weakened immune systems should seek medical help immediately.
Symptoms of kidney infections are always an emergency and should not be neglected. Urological visit should be done immediately if there is fever, back pain, vomiting, or blood in the urine.

Frequently asked questions about urinary tract infections
How do I distinguish a urinary tract infection from a vaginal infection?
Urinary infections usually present with burning during urination and frequent urination, while vaginal infections cause itching, white or odorous discharge, and discomfort during sexual intercourse.
In some cases, symptoms can be confusing, so a medical visit is needed for an accurate diagnosis.
Why do some women experience urinary tract infections after sexual intercourse?
During sex, bacteria from the anal area can be pushed up into the urethra, causing an infection. This is why urinating after sex helps flush out bacteria and reduces the risk of UTIs.
Are urinary tract infections a sign of another health problem?
In some cases, recurrent infections may be a sign of diabetes, kidney stones, or anatomical abnormalities. If infections occur frequently, a more in-depth medical evaluation is necessary.
How long does a urinary tract infection last without treatment?
The infection may last for several days, but there is a risk of it spreading to the kidneys, causing serious complications. Immediate treatment with antibiotics is the safest way to avoid complications.
Can I have a urinary tract infection even if I don't have burning when I urinate?
Yes. Some patients only experience fatigue, abdominal pressure, or frequent urination without a burning sensation. Therefore, any change in urination pattern should be treated with caution.
Why are urinary tract infections more common in women than men?
Women have a shorter urethra and are closer to the anus, making it easier for bacteria to enter the urinary tract. Men are more likely to get urinary tract infections as they get older, often due to prostate problems.
Can I get a urinary tract infection during pregnancy?
Yes. Pregnancy increases the risk of urinary tract infections due to hormonal changes and the pressure of the uterus on the bladder. Regular checkups are part of prenatal care.
Can a urinary tract infection go away without antibiotics?
In some mild cases, it can happen, but this is extremely rare. If not treated properly, the infection can spread to the kidneys. Doctors recommend antibiotic treatment to avoid the risks!
Are UTIs contagious to sexual partners?
Urinary tract infections are not sexually transmitted diseases, but sexual intercourse can trigger them. However, it is important to maintain good hygiene and avoid sexual intercourse until the infection is completely healed.
