ABSTRACT
OBJECTIVE:
The objective of the study was to evaluate prenatal sonographic signs that distinguish male fetuses with posterior urethral valves (PUV) from those with vesicoureteral reflux (VUR).METHODS:
Prenatal data were retrospectively retrieved from all consecutive women delivering between 2003 and 2012 of a male newborn with a postnatal diagnosis of PUV or VUR. Prenatal parameters included fetal bladder characteristics, identification of a dilated posterior urethra, and change in shape and size in the fetal renal pelvis or ureter.RESULTS:
One hundred thirty-six women gave birth to a male newborn with a postnatal diagnosis of PUV (n = 49) or VUR (n = 87). The presence of posterior urethral dilatation [21 (42.9%) fetuses versus 0 (0%), p = 0.000], a thickened fetal bladder wall [37 (75.5%) vs 4 (4.6%), p = 0.000], and anhydramnios [14 (28.6%) vs 0, p = 0.000] were strongly associated with the postnatal diagnosis of PUV. Change in shape and size in the fetal renal pelvis or ureter was observed in 15 (17.2%) of 87 children with VUR versus 1 (2.0%) out of 49 with PUV (p = 0.010).CONCLUSIONS:
Prenatal ultrasound may differentiate with reasonable accuracy male fetuses with a postnatal diagnosis of PUV from those with VUR. © 2016 John Wiley & Sons, Ltd.
