“…Children with a risk for recurrent infections should be evaluated additionally with renal US, VCUG, and in the case of negative results with video-urodynamic studies to rule out anatomical abnormalities such as ectopic ureter (to the vas, ejaculatory duct, or seminal vesicle), ejaculatory duct obstruction, urethral valves, a duplicated urethra, bulbous urethral stricture, prostatic utricle, rectourethral fistula, and urethral ejaculatory duct reflux.
