Q

Important things which UTI in kids may indicate

A

Structural abnormality in UT.

Can lead to scarring, predisposing kids to HTN, impaired GFR and renal failure.

Q

Investigations for UTI

A

Urine dip = WCC and nitrates +
Clean voided urine sample MSC or suprapublic aspiration.
USS if 1st incidence of a UTI for structural abnormality
