A total of 109 children were evaluated for urinary tract infections or for voiding dysfunction without infections. The relationship of voiding dysfunction to urinary infection and vesicoureteral reflux was then examined in girls. The number of males studied was too small for statistical analysis. While 40.6 percent of females with infections had voiding dysfunction, in 66.6 percent of those females having voiding dysfunction infections also developed. Voiding dysfunction was noted in 33.3 percent of females with reflux, probably due to the strong association of reflux and infections. However, all of females with voiding dysfunction, only 20.6 percent also had reflux. These findings were statistically significant (p = 0.01) and suggest that voiding dysfunction is common in girls with infections, perhaps even predisposing to the development of infections. However, voiding dysfunction in this population did not predispose to reflux.
