What Is a Ureterocele?
A ureterocele (pronounced “you-REE-ter-oh-seal”) is a swelling at the end of the ureter—the tube that carries urine from the kidney to the bladder. It looks like a small balloon or bubble where the ureter connects to the bladder.
What Causes It?
Usually present at birth (congenital).
Happens when the opening of the ureter is too narrow, causing urine to back up and stretch the ureter like a water balloon.
Types of Ureteroceles:
Simple (Orthotopic): Stays inside the bladder (more common in adults).
Ectopic: Extends into the urethra (more common in kids, especially girls).
Symptoms:
Frequent UTIs (urinary tract infections)
Pain in the side or belly
Trouble peeing (if the swelling blocks urine flow)
Blood in urine
Wetting problems (in kids)
How Is It Diagnosed?
Doctors use:
Ultrasound (shows the swollen ureter and kidney)
VCUG (a special X-ray to check for urine backup)
CT or MRI scans (for more detailed pictures)
Treatment Options:
Antibiotics (if there’s an infection).
Surgery:
Small cut (endoscopic incision) to drain the ureterocele.
Bigger surgery to fix the ureter if needed.
If the kidney is badly damaged, it might need to be removed.
What Happens If It’s Not Treated?
More infections.
Kidney damage from urine backup.
Bladder problems.
Most people do well after treatment, especially if caught early. Kids with ureteroceles often outgrow the problem after surgery.
