ABSTRACT

Purpose : To evaluate the clinical significance of antenatally detected mild fetal pelviectasia and the role of voiding cystourethrography (VCUG)
Methods : From January 1999 to September 1999, 28 neonates (44 pelviectatic kidneys) with mild fetal pelviectasia (anteroposterial diameter <10 mm) were evaluated by postnatal renal sonography and voiding cystourethrography.
Results : Among 44 mild pelviectatic kidneys, 29 ($65.9%$) kidneys had no pelviectasia and 15 ($34.1%$) kidneys had persistent mild pelviectasia on postnatal renal sonography. Four ($9.1%$) kidneys of 3 males ($10.7%$) without pelviectasia on postnatal renal sonography had vesicoureteral reflux (VUR) on voiding cystourethrography. Vesicoureteral reflux was not correlated with prenatal progression or regression of pelviectasia and was not correlated with postnatal pelviectasia.
Conclusion : All neonate with mild fetal pelviectasia need to undergo voiding cystourethrography for early diagnosis of vesicoureteral reflux even though postnatal renal sonography shows no pelviectasia. (J Korean Soc Pediatr Nephrol 2001 ;5 : 182-87)
