Signs and tests:

Large ureteroceles are usually diagnosed earlier than smaller ones. A ureterocele may be discovered before the baby is born (during a pregnancy ultrasound).

Some people with ureteroceles do not know they have the condition. Often, the diagnosis is made later in life due to kidney stones or infection.

A urinalysis may reveal blood in the urine or signs of urinary tract infection.

The following tests may be performed:

• Abdominal ultrasound
• CT scan of the abdomen
• Cystoscopy (examination of the inside of the bladder)
• Pyelogram
• Radionuclide renal scan
• Voiding cystourethrogram

Blood pressure may be high if there is kidney damage.
