Living with Urachal cyst

A small sac of tissue near the belly button and bladder that often causes no symptoms unless it becomes infected.

Understanding Urachal cyst

A urachal cyst is a sac-like pocket of tissue that forms in the urachus, a tube linking the umbilical cord to the bladder before birth.

The urachus normally disappears before birth, but part of it stays in some people. Urachal cysts can form at any age, though they most often affect older children and adults. They often cause no signs unless an infection or other complication develops.

Signs & symptoms

Many people have no symptoms. If there is a complication such as infection, GARD lists these:

  • Belly pain
  • Fever
  • Pain when urinating
  • Blood in the urine (hematuria)
  • Chills
  • A lump in the belly (abdominal mass)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include kidney specialists and urinary and male reproductive system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
