Asymptomatic Bacteriuria in a Child on Clean Intermittent Catheterization
A nine-year-old girl on clean intermittent catheterization has a positive surveillance urine culture and no symptoms at all, which the stewardship evidence says not to treat and her altered bladder sensation makes genuinely harder to trust.
Adaeze N. has been at school every day this week and asked to stay for an after-school chess club match rather than come straight home — nothing about how she is actually doing suggests illness, which is exactly what makes today's culture result a genuine question rather than an easy call. She is nine years old, has a lumbosacral myelomeningocele, catheterizes five times a day, and had a routine surveillance urine culture drawn at her spina bifida clinic visit that grew more than 100,000 colony-forming units of E. coli per milliliter, with no fever, no new back or flank discomfort, and no change in her catheterized urine's appearance. Her renal-bladder ultrasound from earlier this year was unremarkable, and prior imaging has never shown vesicoureteral reflux on either side.
Colonization is near-universal in children who catheterize regularly, and antibiotic stewardship guidance is consistent that asymptomatic bacteriuria in this population should not be treated — Ottolini and colleagues' 1995 retrospective review of 207 children on clean intermittent catheterization found that in the absence of vesicoureteral reflux, untreated asymptomatic bacteriuria was not a significant risk factor for renal scarring over years of follow-up, and did not require antibiotic therapy. Adaeze's absent reflux places her squarely in the population that finding actually describes. What complicates the stewardship answer in practice, not in principle, is that a retrospective chart review at one pediatric rehabilitation program found antibiotics were still prescribed for asymptomatic bacteriuria at a strikingly high rate despite this guidance — not because clinicians disagree with the principle, usually, but because a child who catheterizes and has altered bladder sensation from her spinal level can have a genuinely hard-to-read presentation, where mild fatigue or a slightly different smell gets treated as ambiguous rather than confidently dismissed.
Colonized, not sick — but who gets to be sure
I wouldn't treat this. She has no symptoms, no fever, no reflux, and a culture alone in a child on clean intermittent catheterization isn't an indication to treat — Ottolini and colleagues' well-known retrospective study of 207 children on CIC found that in the absence of reflux, untreated asymptomatic bacteriuria wasn't associated with renal scarring at all. Treating a colonized, well-appearing child selects for resistant organisms in exactly the population that will need antibiotics again later, for a real infection, when it actually matters.
I hear the stewardship case, and the data you're citing is solid for a child we can confidently call asymptomatic. My hesitation is narrower than disagreeing with the principle — it's that Adaeze's spinal level means her sensory input from the bladder isn't reliable the way an intact child's would be, so “no symptoms” in her case is a genuinely harder read than in a child who'd tell you plainly if something hurt.
I don't think “she's at school and asked to stay for chess club” fully answers that concern — kids with altered sensation can look and function normally right up until a fever starts, precisely because the usual early-warning signal isn't there for her the way it is for other children.
Then let's not force a binary between “treat now” and “ignore it” when the actual disagreement is about how much to trust a well-appearing exam in a child with altered sensation. Don't start antibiotics today — the evidence for her specific picture, no reflux included, is genuinely reassuring. But repeat a focused check-in by phone in 72 hours rather than waiting for her next scheduled visit, with explicit instructions on the subtler signs — new fatigue, appetite change, cloudy or foul-smelling catheterized urine — that would move this from surveillance to treatment.
No antibiotics were started; Adaeze's family received explicit written criteria for when to call before the scheduled 72-hour check-in, and the check-in itself was scheduled regardless of how she's doing by phone.
Not agreed: whether a 72-hour window is short enough given the physiatrist's sensory concern, or whether it simply reflects a schedule that was convenient rather than one calibrated to how fast a real infection could progress in her. The urologist chose 72 hours as a reasonable, evidence-informed interval; the physiatrist would have preferred 24 to 48 hours and agreed to 72 only because the escalation criteria were specific enough to trust the family to use them.
