Ureterocele
Incontinence - ureterocele
A ureterocele is a swelling at the bottom of one of the ureters. Ureters are the tubes that carry urine from the kidney to the bladder. The swollen area can block urine flow.
A ureterocele is a birth defect.
Causes
A ureterocele occurs in the lower part of the ureter. It is the part where the tube enters the bladder. The swollen area prevents urine from moving freely into the bladder. The urine collects in the ureter and stretches its walls. It expands like a water balloon.
A ureterocele can also cause urine to flow backward from the bladder to the kidney. This is called reflux.
Ureteroceles occur in about 1 in 500 people. This condition is equally common in both the left and right ureters.
Symptoms
Most people with ureteroceles do not have any symptoms. When symptoms do occur, they may include:
-
Abdominal pain

Some people with ureteroceles do not know they have the condition. Often, the problem is found later in life due to kidney stones or infection.
Kidney stones
A kidney stone is a solid mass made up of tiny crystals. One or more stones can be in the kidney or ureter at the same time.
A urinalysis may reveal blood in the urine or signs of urinary tract infection.

Blood pressure may be high if there is kidney damage.
Treatment
Antibiotics are often given to prevent further infections until surgery can be done.
The goal of treatment is to eliminate of the blockage. Drains placed in the ureter or renal area ( stents ) may provide short-term relief of symptoms.

Surgery to repair the ureterocele cures the condition in most cases. Your surgeon may cut into the ureterocele. Another surgery may involve removing the ureterocele and reattaching the ureter to the bladder. The type of surgery depends on your age, overall health, and extent of the blockage.
Outlook (Prognosis)
The outcome varies. The damage may be temporary if the blockage can be cured. However, damage to the kidney may be permanent if the condition doesn't go away.
Kidney failure is uncommon. The other kidney will most often work normally.
Possible Complications
Complications may include:
- Long-term bladder damage (incontinence/urinary retention)
-
Long-term
kidney damage
, including loss of function in one kidney
Kidney damage
Injury to the kidney and ureter is damage to the organs of the upper urinary tract.

Ureterocele - illustration
A ureterocele is a congenital (from birth) disorder in which the ureter develops an out-pouching as it enters the bladder. Ureteroceles usually occur after frequent urinary tract infections. Treatment of the ureterocele usually involves the placement of a stent to relieve the obstruction and/or surgical repair.
