The ureterocele orifice may be normal or patulous, but the distal ureter leading to it becomes obstructed by the activity of the internal sphincter.
Surgical therapy for both pediatric and adult ureteroceles may include endoscopic incision or transurethral unroofing of the ureterocele in the adult patient, upper pole heminephrectomy and partial ureterectomy with ureterocele decompression, ureteropyelostomy, excision of ureterocele and ureteral reimplantation, and nephroureterectomy.

A ureterocele is the herniation of the cystic end of a lower ureter, lying between the mucosa and the bladder muscle, ballooning inside the bladder.
Ureteroceles are also associated with the DiGeorge syndrome characterized by renal anomalies (hydroureteronephrosis with ureterocele, multicystic kidneys, renal agenesis), cardiac abnormalities (ventricular septal defect, double-outlet right ventricle) and absence of the thymus due to a deletion of chromosome 22q11[7].
Other techniques are early unroofing of ureteroceles or the endoscopic injection of Teflon, which causes the vesico-ureteral reflux to disappear in most cases (70%).

  If the ureterocele is not associated with upper urinary tract infection or bladder outlet obstruction, one may simply observe the patient on prophylactic antibiotics until the time of reconstruction.
We believe that primary single stage lower urinary tract surgery in patients with non-functional renal moieties associated with ureteroceles, ectopia, and/or reflux is superior to other approaches that require upper urinary tract ablative surgery.

Sometimes people with ureteroceles don´t know they have the condition, or the diagnosis is made later in life due to kidney stones.

The protocol chosen defines the treatment of the urinary tract as a single entity, without isolating the treatment of ureteroceles, which we consider to be an integral part of a complex of anatomical deformities, whose entirety, in its detrimental effect on each individual component determines its clinical consequences and its treatment.
None of those with ureterocele showed post-operative lesions, although localized vesical thickening was visible in four and one developed (72 m after total nephrectomy) a vesical diverticulum at the site of the ureterocele described earlier, with reflux at the ureteral stump.
All of the ureteroceles resolved spontaneously without sequelae, except in the case of one patient, who came to present periureteral vesical diverticulum, after a long period of observation (6 years).

 MedPix™ 1103: Ureterocele / Vesicoureteral Reflux - Medical Image Database and Atlas
Ureteroceles are commonly associated with a duplicated renal collecting system and typically involve the ureter draining the upper pole moiety ('half'), are obstructing - causing a hydronephrotic upper pole.
Ureteroceles may be diagnosed by ultrasound (including prenatal), which demonstrate both the secondary hydronephrosis and an intravesical cystic dilatation of the ureter.
VCUG (V-oiding C-ysto U-rethro G-ram) can demonstrate the size and location of the ureterocele as well as presence of reflux, which is commonly seen in the ipsilateral lower pole but can also be present in the contralateral system if the ureterocele is large enough to distort the bladder trigone and the opposite ureteral tunnel.
