Resumen

DURAN ALVAREZ, Sandalio et al. Hidronefrosis prenatal secundaria a reflujo vesicoureteral. Rev Cubana Pediatr [online]. 2003, vol.75, n.3. ISSN 0034-7531.

Cystourethrography was performed on 54 children of whom 37 were males, who had been previously detected dilatation of one or both renal pelvis through maternal-fetal ultrasound (20 had bilateral dilatation). The test detected vesicoureteral reflux in 12 of the 54(12 %); 9 of them were males. The 9 boys had 12 refluxed renal units and 2 of the 3 girls presented with bilateral reflux. Six of the 7 high grade (IV and V) refluxes corresponded to boys. The static scintigraphic study (TC 99m-DMSA) showed that four kidneys were affected with high grade reflux and one with grade II reflux, without having history of infections of any kind. The relative renal function of these kidneys ranged from 9 to 40 %. Low grade vesicoureteral reflux (I and II) was present in two patients who did not show pelvic dilatation in the renal unit with these refluxes. All high grade refluxes corresponded to severe hydronephrotic dilatations.
