The differential diagnosis of ANH, in order of likelihood, includes transient primary hydronephrosis, uretero-pelvic junction obstruction (UPJO), vesicoureteric reflux (VUR), uretero-vesical junction obstruction (UVJO) or primary non-obstructive megaureter, ureterocele
, ectopic ureter and causes of megacystis.
is a submucosal part dilatation of the ureter in the intramural area.

Another 75 patients of the entire 907 subjects who were tracked had other conditions (ureterocele
: eight cases; stones: seven cases; cystic dysplasia: 43 cases; megaureter: 15 cases; and Wilms' tumor: two cases) that did not progress to CKD.

Girls with ureteroceles
may present with febrile urinary tract infections, abdominal masses, or perineal masses, and they may report straining upon urination.
After posterior urethral valves, ureteropelvic junction (UPJ) obstruction accounted for 3.6%, obstructive megaureter 3.5%, some form of urethral hypoplasia/atresia 2.3%, ureterocele
1.7%, and other complex uropathies accounted for 5.9%.
The holmium laser has also been used to incise ureteroceles
. The incidence of ureterocele
is as high as 1 in 500 (Coplan & Duckett, 1995).

Although specific and definitive management for ureteroceles
differ in some individuals, the goals of treatment are the same: preservation of renal function; prevention of infection, obstruction and reflux; and maintenance of urinary continence.
Examples include ureterocele
, bladder stones not visualized on the preliminary image, or urothelial mass.
