Ureterocele

  • Definition
    • A ureterocele is a swelling at the bottom of one of the tubes (ureters) 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, 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 to 1 in 4,000 people. Ureteroceles are equally common in both the left and right ureters.

  • Symptoms
  • Exams and Tests
  • 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. Surgery involves making a cut into the ureterocele or 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, especially 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
      • Urinary tract infection that keeps coming back
  • When to Contact a Medical Professional
    • Call your health care provider if you have symptoms of ureterocele.
