Miction uretrocystography was performed in 71 children (48 boys), among whom the maternofetal ultrasonographic study had detected a pelvic renal dilation that was confirmed in the postnatal renal ultrasound. Vesicoureteral reflux (VUR) was found in 16 (22.5 %) and renal reflowing units (RRU) in 23 (16 %). The static gammagraphic study (Tc 99m-DMSA) showed alteration of the differential renal function in 6 patients, 1 with degree II VUR and 5 with degree IV and V VUR. The degree of functional affectation varied from mild to essentially nonfunctional. One of these patients had history of urinary infection in the neonatal period, whereas the other five did not. These data support the criterion that in VUR, mainly in IV and V degrees, the kidney may be affected before birth.
