Vesicoureteral reflux in infants with prenatal hydronephrosis confirmed at birth: racial differences.

Abstract

We compared the incidence of vesicoureteral reflux in black and nonblack patients in whom prenatal hydronephrosis was confirmed postnatally. We reviewed the records of 58 black and 51 nonblack patients with confirmed hydronephrosis who underwent voiding cystourethrography. Reflux was present in 9 cases (8.3%). The prevalence of reflux in black and nonblack patients was 0 and 17.6%, respectively. The absence of vesicoureteral reflux in black infants with prenatal hydronephrosis and the 17.6% incidence in nonblack infants suggest that voiding cystourethrography should not be routinely performed in the black population, although it should continue to be done on a routine basis in the nonblack population.
