Risk Factors of Shim et al for Recurrent Urinary Tract Infections (UTI) in an Infant

Description

Shim et al reported risk factors for recurrent urinary tract infections (UTI) in an infant. These can help to identify a patient who may benefit from more aggressive management. The authors are from Ewha Womans University and Kangnam Sacred Heart Hospital.


Patient: infant less than 1 year of age with a first urinary tract infection

 

Recurrent UTI: repeated episodes of significant bacteriuria with/without pyuria and with unexplained fever or urinary signs/symptoms (dysuria, pus in diaper, crying on urination)

 

The most important risk factor is an abnormal urinary tract, particularly vesicoureteral reflux (VUR).

 

Risk factors if the urinary tract is normal:

(1) male with non-retractile prepuce (odds ratio 8.8)

(2) age <= 6 months (odds ratio 72.7)

(3) acute pyelonephritis (odds ratio 4.6)
