Itʹs incidence in neonates is 0.1 - 1% and it is more common in premature , low birth weight and uncircumcission male infants. More reports suggested association between hyperbilirubinemia with unknown etiology and bacterial infection including UTI, but AAP has not still recommended to evaluate such infections as routine. This study did to evaluate the incidence of UTI in icteric neonates without fever and other signs. Methods: This was a cross sectional study on 400 hospitalized icteric neonates without fever and other signs at Javaheri hospital in 2003-2006. In these neonates urinalysis was done by bag and if urinalysis or urine culture was positive, then the test repeated through suprapubic procedure.

Results: The incidence of UTI in hospitalized icteric neonate was 1.8%. It was more common in males and the most common isolated organism was E coli. There was unilateral dilatation of pyelocaliceal system in one case(14.3%).Conclusion: In attention to low incidence of UTI in icteric neonates without other signs , it is recommended to perform urine test in prolonged jaundice with unknown etiology, direct hyperbilirubinemia or when hyperbilirubinemia decreases difficulty
