- In the pediatric population, ureteroceles are most commonly diagnosed on prenatal ultrasounds, and symptomatic infants may present with infections or failure to thrive. Most patients with ureteroceles have ipsilateral hydronephrosis and/or dysplastic kidney.
- Adult ureteroceles are typically found incidentally and are asymptomatic, but when symptomatic can result in urinary tract infections (UTIs), urinary retention, or hematuria.
- Single system – Single kidney, collecting system, and ureter.
- Duplex system – Kidneys that have completely duplicated ureters.
- Orthotopic (intravesical) – Ureterocele contained within the bladder that may prolapse into and beyond the bladder neck and usually arises from a single renal unit with one collecting system. More commonly diagnosed in adults.
- Ectopic (extravesical) – Ureteroceles with tissue that originates at the bladder neck or beyond and typically arises from the upper pole moiety of a duplicated collecting system. More common in the pediatric population.
