Abstract
OBJECTIVE: To determine any ethnic difference in the rate of spontaneous decrease in the incidence of primary vesico-ureteral reflux (VUR). MATERIALS AND METHODS: Voiding cystourethrograms on 738 patients with urinary tract infection were reviewed, and the incidence of primary vesico-urethral reflux was correlated with age, gender and ethnic origin. RESULTS: There was a gradual decrease in the incidence of primary VUR in whites between 0-10 years, while the incidence of primary VUR in blacks was very low and remained the same. After 10 years of age, no difference was present. CONCLUSION: The possibility of delayed maturation of the antireflux mechanism in whites is considered as a possible explanation, and the possibility of an ethnic basis for this is suggested.
