UTI in kids – big deal?

8% of girls and 2% of boys are diagnosed with at least one UTI by the age of seven years.

Phew, but what about scarring ?

?Does UTI progress to pyelonephritis ?Does UTI progress to scarring

DONE! Causes scarring: test and treat

Hang on…is scarring bad?

Old guidelines based on 2 studies Gill et al Chart Review. N=100 children with hypertension. Reflux nephropathy believed to be the cause in 14. No long-term follow up. Shore and Gorelick A review of several very small studies. Many were of children with abN IVU. Suggestion of decreased GFR

Hang on…is scarring bad? Multiple other studies since 2000 Prospective, controlled, large Long-term follow-up Confirm rate of scarring with paediatric UTI No clinically or statistically significant increased rate of CKD or decreased GFR Epidemiological data also

Stop giving antibiotics to kids with UTI????????

So, what’re you saying? Stop giving antibiotics to kids with UTI???????? Stop getting urine samples when UTI suspected???????

So, what’re you saying? Stop giving antibiotics to kids with UTI???????? Stop getting urine samples when UTI suspected??????? NO

What I am saying

The evidence is such that the role of antibiotics in uncomplicated paediatric UTI should be questioned with good quality RCTs. Until then, antibiotics for all paediatric UTI remain a standard of care.

What I am saying The evidence is such that the role of antibiotics in uncomplicated paediatric UTI should be questioned with good quality RCTs. Until then, antibiotics for all paediatric UTI remain a standard of care. The evidence is such that aggressive policies demanding same day urinary collection in low risk, well infants and small children with FWS, outside the neonatal period, have no basis in evidence and can be ignored.
