BACKGROUND/AIM Ureteropelvic junction obstruction and vesicoureteral reflux are the most frequent entities identified on the basis of antenatal hydronephrosis. The aim of this study was to determine the incidence and pattern of abnormal renal scintigraphy findings in postnatal investigation of children with antenatal hydronephrosis. METHODS Twenty-four infants (19 boys and five girls) present...

OBJECTIVES The aim of this study was to evaluate renal function and the need for postnatal treatment--antibiotic therapy and/or surgery--in relation to the grade of fetal renal pelvic dilatation (RPD) found on third-trimester ultrasound examination. METHODS The retrospective study included 78 children, born between 1995 and 2000, with 115 dilated fetal renal pelvic units. The children were al...

Radiologic imaging of the newborn detected prenatally with hydronephrosis should follow a systematic approach. Upper and lower urinary tract imaging should be performed in most cases in order to determine the etiology and gauge the use of future imaging. An overview of renal ultrasound, voiding cystourethrography, renal scintigraphy, and magnetic resonance urography in the setting of antenatal ...

Background: Antenatal hydronephrosis is known to be associated with vesicoureteral reflux (VUR). However, the incidence of VUR in postnatally diagnosed hydronephrosis is unknown. Hypothesis: The prevalence of VUR is increased in infants diagnosed with hydronephrosis on postnatal ultrasonography. Methods: Infants admitted to our NICU between January 1998 and September 2007 and diagnosed with hyd...

OBJECTIVE To define the clinical outcome in isolated antenatal hydronephrosis (ANH), defined as pelviectasis without vesicoureteral reflux or urinary tract obstruction. STUDY DESIGN AND PATIENTS We analyzed prospectively gathered data from patients with isolated ANH. Pelviectasis, graded using the anterior-posterior diameter reference criteria, was defined by the status of the more severely a...
