Urinary tract infection (UTI) in children is one of the most common infections (1). The bacterial infection can affect different parts of the urinary tract, including the urethra, urinary bladder or kidneys. UTIs
Infection of any part of the urinary system, including kidneys, ureters, bladder, and urethra.
Full Answer
Key points about a UTI in children. A urinary tract infection is inflammation of part of the system that takes urine out of the body. Most infections are caused by bacteria from the digestive tract. The most common is Escherichia coli (E. coli) bacteria. These normally live in the colon. A UTI is not common in children younger than age 5.
Urethra infection and bladder infection are the most common forms of UTI in children, but these infections can also affect the ureters and kidneys. If your child has a UTI, you may notice the following symptoms: Frequent urination, although very little urine may be produced

Who needs evaluation for UTI Clinical diagnosis of UTI is unreliable, so many children with fever or symptoms of UTI need a urine sample to exclude or make the diagnosis. Urine samples should be collected before starting antibiotics, but therapy should not be delayed in the septic child.
Young children with UTIs may have a fever, poor appetite, vomiting, or no symptoms at all. Most UTIs in children only involve the bladder. It may spread to the kidneys.
Urinary tract infections don't always cause signs and symptoms, but when they do they may include:A strong, persistent urge to urinate.A burning sensation when urinating.Passing frequent, small amounts of urine.Urine that appears cloudy.Urine that appears red, bright pink or cola-colored — a sign of blood in the urine.More items...•
Physical examination findings in pediatric patients with UTI can be summarized as follows: Costovertebral angle tenderness. Abdominal tenderness to palpation. Suprapubic tenderness to palpation.
The most common UTIs are bladder infections, and symptoms include:frequent urges to urinate.a burning or itching sensation while urinating.feeling that the bladder is full, even after urinating.cloudy urine.blood in the urine.foul-smelling urine.pain during sex.pressure in the lower back or lower abdomen.More items...
How Do Kids Get UTIs? It happens when bacteria from their skin or poop get into the urinary tract and multiply. These nasty germs can cause infections anywhere in the urinary tract, which is made up of the: Kidneys, which filter wastes and extra water out of the blood to make urine.
What causes a urinary tract infection (UTI)? Urinary tract infections are caused by microorganisms — usually bacteria — that enter the urethra and bladder, causing inflammation and infection. Though a UTI most commonly happens in the urethra and bladder, bacteria can also travel up the ureters and infect your kidneys.
Here are some signs of a UTI:Pain, burning, or a stinging feeling when urinating.Urinating often or feeling an urgent need to urinate, even without passing urine.Foul-smelling urine that may look cloudy or have blood in it.Fever.Pain in the low back or around the bladder.
The symptoms and signs are non-specific throughout infancy. Unexplained fever is the most common symptom of UTI during the first two years of life. After the second year of life, symptoms and signs of pyelonephritis include fever, chills, rigor, flank pain, and costovertebral angle tenderness.
UTIs can be found by analyzing a urine sample. The urine is examined under a microscope for bacteria or white blood cells, which are signs of infection. Your health care provider may also take a urine culture. This is a test that detects and identifies bacteria and yeast in the urine, which may be causing a UTI.
The recommended initial antibiotic for most children with UTI is trimethoprim/sulfamethoxazole (Bactrim, Septra). Alternative antibiotics include amoxicillin/clavulanate (Augmentin) or cephalosporins, such as cefixime (Suprax), cefpodoxime, cefprozil (Cefzil), or cephalexin (Keflex).
Signs and symptoms of bladder infection (cystitis) in men include:Frequent urination.Strong, persistent urge to urinate (urgency)Burning or tingling sensation during or just after urination (dysuria)Low-grade fever.Cloudy urine with a strong odor.Blood in urine (hematuria)More items...
A urinary tract infection is caused by micro-organisms, usually a bacteria called Escherichia coli (E. coli). The urethra, bladder, vagina or kidneys can be affected. Even though urinary tract infections are very common, treatment with antibiotics may be needed, so seek advice from your doctor.
It's important to know that UTI symptoms are similar to symptoms of other conditions and infections. Always contact your child's primary care doctor when symptoms appear. He or she will ask about your child's symptoms to determine if an examination is necessary.
Bacteria, often the intestinal bacteria E. coli, can easily enter the urinary tract from the skin around the anus. UTIs are more common in girls, especially during potty training, because a girl's urethra is shorter and closer to the anus. Uncircumcised baby boys also have a slightly elevated risk. Some risk factors for UTI are not preventable, including:
To diagnose a baby or young child, the doctor may need to: Insert a catheter through his or her urethra and into the bladder to collect urine.
Urethra infection and bladder infection are the most common forms of UTI in children, but these infections can also affect the ureters and kidneys. If your child has a UTI, you may notice the following symptoms: 1 Bedwetting 2 Fever (occasionally the only symptom in babies) 3 Foul-smelling, cloudy or blood-tinged urine 4 Frequent urination, although very little urine may be produced 5 Fussiness 6 Nausea, vomiting or loss of appetite 7 Pain below your child's belly button 8 Pain or burning sensation when your child urinates 9 Waking at night to urinate
If your child has a UTI, you may notice the following symptoms: Bedwetting. Fever (occasionally the only symptom in babies)
How is a UTI in children treated? A UTI in children is commonly treated using antibiotics. The doctor will send your child's urine sample to the lab, but analysis may take a couple of days. In the meantime, he or she will prescribe your child an antibiotic that treats the most common bacteria that cause UTIs.
Insert a catheter through his or her urethra and into the bladder to collect urine. Collect urine by attaching a bag around his or her genitals, within a diaper, until the child urinates. This method carries a risk of urine contamination by normal skin bacteria.
Urinary tract infections (UTIs) are a common and potentially serious bacterial infection of childhood . History and examination findings can be non-specific, so a urine sample is required to diagnose UTI. Sample collection in young precontinent children can be challenging. Bedside dipstick tests are useful for screening, but urine culture is required for diagnostic confirmation. Antibiotic therapy must be guided by local guidelines due to increasing antibiotic resistance. Duration of therapy and indications for imaging remain controversial topics and guidelines lack consensus. This article presents an overview of paediatric UTI diagnosis and management, with highlights of recent advances and evidence updates.
Non-invasive methods involve waiting for spontaneous urine voiding, then opportunistic collection with a nappy pad, bag, or ‘clean catch’ of the urine stream. These methods seem convenient and practical. However, pads and bags have high rates of contamination up to 50%–60%,2 15understandable given their close contact with skin under the nappy area. Pad and bag samples can be useful for dipstick screening but are unreliable for culture. Cotton wool ball collection is specifically discouraged.16Clean catch has the lowest contamination of all non-invasive methods at around 25%,17but attempts can be time-consuming or unsuccessful. Simple voiding stimulation methods such as the Quick-Wee technique can increase the speed and success of clean catch.18 19
Urine dipsticks are a quick, inexpensive bedside screening tool. Chemical reagent strips change colour in the presence of leucocyte esterase (an enzyme present in leucocytes) and nitrites, which may arise from UTI.26Leucocytes generally appear in the urine in response to UTI. However, sterile pyuria can occur with other infections. Enterococcus, Klebsiellaand Pseudomonasspecies are also less likely to produce pyuria than E.coliin children with symptomatic UTI.27Most uropathogens convert dietary nitrates into urinary nitrites. However, not all do, including Enterococcusand Klebsiellaspecies.26Dipsticks are also less reliable in young infants, where frequent voiding flushes substrates out of the bladder.26
Short-term morbidity can arise from infection within the renal system. This includes systemic features including poor oral intake and dehydration, and uncommon local complications including perinephric abscess formation. Short-term morbidity also arises from haematogenous uropathogen spread. Bactaraemic UTI has been best studied in infants, as this population is most likely to have blood cultures collected during febrile illnesses. Approximately 5% of infants <12 months with UTI have bacteraemia identified,10depending on study setting. Bacteraemia can then lead to urosepsis. Meningitis can also occur with haematogenous spread to the cerebrospinal fluid (CSF). The risk of coexisting meningitis and UTI is 1% in the neonatal period,11suggesting a low threshold to perform lumbar puncture in this age group. Beyond 1 month, the risk is smaller.11Typical empirical UTI antibiotics have poor CSF penetration and inadequate duration to treat bacterial meningitis.
This typically leads to abdominal pain and loin tenderness, with systemic features such as fever, anorexia, vomiting, lethargy and malaise. Lower tract UTI involves infection within the bladder (cystitis) and urethra, with localised symptoms such as lower abdominal or suprapubic pain, dysuria, urinary frequency and urgency. Older children may present with signs and symptoms suggesting the site of infection. In younger patients, these classical signs are often absent, and differentiating between upper and lower UTI is less obvious.
Outside early infancy and if the child is not unwell, it may be reasonable to wait 24 hours for collection to see if an alternative focus emerges.16
Invasive methods extract urine directly from the bladder by urethral catheterisation or suprapubic needle aspiration (SPA). These methods are effective but require expertise and equipment to perform and are painful and distressing for the child. Contamination from catheter and SPA is low, at 10% and 1% respectively,17so these methods are more reliable for culture and diagnosis.
