Health condition
Recurrent UTIs in children
Repeated urine infections in a child need more than repeated antibiotics: assessment looks for the underlying drivers - constipation, incomplete bladder emptying, and in some children urine reflux towards the kidneys.

Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
UTI symptoms in children: burning, frequency and accidents in older children; fever, vomiting and irritability may be the only signs in little ones
-
A fever with a UTI suggests kidney involvement and always warrants prompt treatment
-
The commonest fixable contributors are constipation and dysfunctional toileting habits rather than anatomical abnormality
-
Specialist: a consultant paediatric nephrologist or urologist; ultrasound is the first-line scan, with further imaging only for selected children
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
One urine infection is common in childhood; a pattern of repeated infections deserves a proper look at why. In most children the answer lies in the everyday mechanics - constipation pressing on the bladder, holding on too long, rushed incomplete emptying, inadequate drinking - while a smaller group have vesicoureteric reflux, where urine washes back up towards the kidneys during voiding, or other structural variations that show up on scans. Febrile infections matter most, because infection reaching the kidneys can scar them.
Diagnosis and treatment routes
Assessment includes a review of bowel and bladder habits (usually the richest source of fixes), an ultrasound of the kidneys and bladder, and in younger children or after atypical or recurrent febrile infections, more detailed imaging to look for reflux or scarring. Management combines aggressive treatment of constipation, structured drinking and voiding routines, prompt testing and treatment of each suspected infection, and for selected children a period of low-dose preventive antibiotics; surgery is reserved for the few with significant reflux that does not settle. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant paediatric nephrologist or paediatric urologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.

Frequently asked
Common questions about Recurrent UTIs in children.
Quick, plain-English answers to what people ask us most.
-
What causes recurrent UTIs in children?
Repeated urine infections in a child need more than repeated antibiotics: assessment looks for underlying drivers such as constipation, incomplete bladder emptying, and in some children, vesicoureteral reflux or other structural abnormalities.
-
Are recurrent UTIs in children serious?
Yes, they are worth taking seriously because repeated kidney-involving infections can cause scarring over time, particularly in younger children, so finding and addressing the underlying cause protects long-term kidney health.
-
How are recurrent UTIs in children investigated?
Investigation typically includes urine culture, an assessment for constipation and voiding habits, and imaging such as ultrasound or specialised scans to check for structural abnormalities like reflux.
-
How are recurrent UTIs in children treated?
Treatment includes antibiotics for active infections, management of constipation if present, and in some children, low-dose preventive antibiotics or, rarely, surgical correction of a structural abnormality.
-
Does vesicoureteral reflux always need surgery?
No - many children with mild reflux are managed with monitoring and preventive antibiotics as they often improve as they grow, with surgery reserved for more significant reflux or breakthrough infections.
-
Recurrent UTIs in children vs adults - what's the difference?
Children are more likely to have an underlying structural or functional driver such as reflux or constipation prompting fuller investigation, whereas adult recurrence more often relates to behavioural or hormonal factors.
-
When should I see a specialist about my child's recurrent UTIs?
See your GP after a second confirmed UTI in a child for referral to a paediatric nephrologist or urologist. A private specialist can typically be seen within about two weeks, against much longer routine NHS waits.
