Mild fetal hydronephrosis indicating vesicoureteric reflux.

Significance of vesicoureteric reflux.

Vesicoureteric reflux in children.

Vesicoureteric reflux is defined as the retrograde passage of urine from the bladder into one or both ureters and often up to the kidneys, and mainly affects babies and infants. In severe cases dilatation of the ureter, renal pelvis, and calyces might be seen. Traditionally it was thought that only a low percentage of children have vesicoureteric reflux, but studies have suggested as many as 25...

Diagnosis of Vesicoureteric Reflux and Reflux Nephropathy

FIGURE 8-12 International system of radiographic grading of vesicoureteral reflux (VUR). The severity of VUR is most frequently classified according to the International Grading System of Vesicoureteral Reflux, using a standardized technique for performance of voiding cystourethrography. The definitions of this system are illustrated in Figure 8-4 and are as follows. In grade I, reflux only int...

Voiding cystourethrogram in the diagnosis of vesicoureteric reflux in children with antenatally diagnosed hydronephrosis

UNLABELLED Prenatal ultrasonography has revolutionized the detection and management of many urological abnormalities. Vesicoureteric reflux (VUR) which develops in 10% to 15% of cases of prenatal hydronephrosis, is difficult to predict prenatally. While all children with prenatal hydronephrosis should undergo ultrasonography within the first few weeks of life, there seems to be controversy rega...

Mild Postnatal Hydronephrosis Is Not Associated With Increased Vesicoureteral Reflux

Background: Antenatal hydronephrosis is known to be associated with vesicoureteral reflux (VUR). However, the incidence of VUR in postnatally diagnosed hydronephrosis is unknown. Hypothesis: The prevalence of VUR is increased in infants diagnosed with hydronephrosis on postnatal ultrasonography. Methods: Infants admitted to our NICU between January 1998 and September 2007 and diagnosed with hyd...
