- Various symptoms High fever, pain on urination, cloudy urine, irritability in infants
- Diagnosis by urinalysis, in particularECBU
- Treatment by antibiotic therapy5 to 10 days
- Prevention : good hydration, appropriate intimate hygiene, combating constipation
- Urgent consultation if fever in an infant or intense pain
Urinary tract infection is a common ailment in children, and can occur at any age. As a urologist, I regularly see how worried parents are about this condition. It's vital to know how to recognise the signs so you can act quickly and avoid complications. Throughout this text, I will guide you through the symptoms, diagnosis and management of urinary tract infection in children.
Signs of urinary tract infection in children
Detecting a urinary infection in a child can be tricky, because the symptoms vary according to age. Here are the main signs to look out for:
- Persistent high fever (39°C or more)
- Pain or burning when urinating
- Frequent urination
- Cloudy or foul-smelling urine
- Abdominal or back pain
In infants, irritability and unusual crying may be clues. Fatigue and loss of appetite are also symptoms to look out for. In my career, I've often found that parents overlook these signs, mistakenly attributing them to simple temporary tiredness.
Age and gender differences
It should be noted that urinary tract infections are more common in girls after the age of 2. This is due to the female anatomy, with a shorter urethra making it easier for bacteria to ascend. In boys, they are rarer but may be associated with urinary tract malformations.
Risk of complications
An untreated urinary tract infection can develop into pyelonephritis, a more serious infection affecting the kidneys. That's why it's vital to seek help quickly if you have any doubts. I always stress to my patients the importance of early treatment to avoid these potentially serious complications.
Diagnosis and management of urinary tract infection
When a urinary tract infection is suspected, the diagnosis is based primarily on urinalysis. The urine cytobacteriological examination (UCE) is the gold standard for detecting the presence of bacteria and white blood cells in urine.
Urine collection methods
Collecting urine can be tricky, especially in infants. Several techniques are used:
| Age | Collection method |
|---|---|
| Infant | Sterile bag, catheterisation, suprapubic puncture |
| Older children | Intermediate stream urine dipstick |
The choice of method depends on the child's age and the urgency of the situation. As a specialist, I always recommend the most suitable and least invasive method for the child's comfort.
Antibiotic treatment
Once the diagnosis has been made, treatment is based on appropriate antibiotic therapy. Treatment generally lasts between 5 and 10 days, depending on the child's age and the severity of the infection. In some cases, particularly in infants, hospitalisation may be necessary to monitor progress and administer the treatment intravenously.
It is crucial to follow the medical prescription to the letter to avoid recurrences and the development of bacterial resistance. I always stress to parents the importance of completing the treatment, even if symptoms improve rapidly.
Prevention and contributing factors
Prevention plays an essential role in the fight against urinary tract infections in children. By understanding the contributing factors, we can put in place effective measures to reduce the risks.
Risk factors to watch out for
A number of factors can contribute to the development of a urinary tract infection:
- Urinary tract malformations (vesico-ureteral reflux) in infants
- Chronic constipation
- Urinary retention
- Lack of hydration
- Poor personal hygiene
In my practice, I've often found that constipation is a neglected yet frequent factor. It encourages stool stagnation and therefore bacterial proliferation near the urethra.
Effective preventive measures
To prevent urinary tract infections, here are a few tips that I always give my patients:
- Keep your child well hydrated throughout the day
- Encourage them to urinate regularly and not to hold back
- Ensure proper intimate hygiene, paying particular attention to the direction of cleansing (from front to back in the case of girls).
- Fight constipation with a high-fibre diet and regular exercise
- Choose cotton underwear and avoid clothes that are too tight
By taking these simple steps, you can significantly reduce the risk of your child developing a urinary tract infection. Don't hesitate to consult your doctor or urologist if you have any questions or concerns.
When is an emergency consultation necessary?
Some situations require rapid medical consultation, or even emergency treatment. Here are the cases where you should act without delay:
Consult immediately if :
- Your baby under one month old has a fever
- Your child suffers from severe pain
- You notice a change in your general condition (extreme tiredness, refusal to eat)
Within 24 to 48 hours if :
- Fever persists in an older child
- Urinary symptoms intensify despite comfort measures
As a specialist urologist, I cannot stress enough the importance of prompt treatment. An early diagnosis can help avoid complications and ensure your child recovers more quickly.
Remember that every child is unique and that symptoms may vary. If in doubt, it's always best to seek advice. Your vigilance and responsiveness are your best allies in preserving your child's urinary health.
