Fetal vesicoureteral reflux.

Intrauterine fetal vesicoureteral reflux has been demonstrated in a 25-week fetus. A voiding cystourethrogram when the patient was 1 year old showed persistence of the bilateral reflux. No urinary tract infectious have been documented. A survey of other physicians performing fetal transfusions indicates that fetal cystograms are infrequently obtained and that vesicoureteral reflux has been observed by ourselves and one other contributing physician. The incidence of reflux in fetal cystograms reviewed appears to be higher than would be expected when compared to normal premature babies, newborns, infants and children. This procedure provides an unusual opportunity to document intrauterine fetal vesicoureteral reflux and later obtain followup cystourethrograms in these children to determine the resolution or progression of this urinary tract abormality.
