The purpose of a VCUG is to assess for the precise cause of AHN, and is especially helpful in excluding entities such as VUR, ureteroceles
and urethral anomalies such as PUV.

With an incidence of 1/5000 to 1/12000 per birth, ureteroceles
belong to the most common urinary tract anomalies in humans [1, 2].
Other authors have questioned the clinical significance of hydronephrosis and suggest resorting to VCUG when the patient has ultrasound findings consistent with renal dysplasia or hypoplasia, renal cystic disease, cortical thinning, loss of corticomedullary differentiation, high-grade unilateral or bilateral dilation, alteration in the kidney number or kidney size, presence of ureteroceles
or hydroureteronephrosis, or suspected bladder outlet obstruction (such as thickening of the bladder wall or ureters) (1,6.15).
(9) The formation of a urinoma requires a urine-producing kidney, a leaking collecting system and an infra-vesical or ureteral obstruction (e.g., posterior urethral valves, UPJ obstruction, obstructive ureteroceles
, or ureteral atresia or obstruction).
sao anomalias congenitas que se caracterizam por dilatacoes cisticas da regiao submucosa que acometem o segmento distal do ureter.
Congenital anomalies of the ureters include complete and partial duplication, ectopic ureteral insertion, and orthotopic or ectopic ureteroceles
The AAP 1999 practice parameter recommends that all children with a first urinary tract infection (UTI) undergo renal ultrasound to detect abnormalities such as hydronephrosis, bladder hypertrophy, and ureteroceles
; and either a voiding cystourethrogram (VCUG) or direct radionuclide cystography (RNC) to evaluate the presence and degree of vesicoureter al reflux (VUR), Dr.
Se suele presentar una dilatacion difusa y regular, aunque tambien es posible encontrar ureteroceles
. La dilatacion es mas frecuente, aunque no patognomonica, en ureteres intramurales.
The most common congenital anomalies in the upper urinary tract that can cause urinary incontinence in females are ectopic ureters and ectopic ureteroceles
are classified as being either intravesical (within the bladder) or ectopic (some portion extends beyond the bladder neck).
