Vesicoureteral reflux in infants with prenatal hydronephrosis confirmed atbirth: Racial differences

Purpose: We compared the incidence of vesicoureteral reflux in black and no nblack patients in whom prenatal hydronephrosis was confirmed postnatally. Materials and Methods: We reviewed the records of 58 black and 51 nonblack patients with confirmed hydronephrosis who underwent voiding cystourethrogr aphy. Results: Reflux was present in 9 cases (8.3%). The prevalence of reflux in black and nonblack patients was 6 and 17.6%, respectively. Conclusions: The absence of vesicoureteral reflux in black infants with pre natal hydronephrosis and the 17.6% incidence in nonblack infants suggest th at voiding cystourethrography should not be routinely performed in the blac k population, although it should continue to be done on a routine basis in the nonblack population.
