A urachal cyst is a sac of tissue that develops between the bladder and belly button. The urachus is the remainder of a channel that is formed during the first trimester of pregnancy. It usually disappears before a baby is born, but parts of it may remain in some people. When this happens, a urachal cyst can develop. They are most common in older children and adults.

What are the signs and symptoms of a urachal cyst?
Urachal cysts usually have no symptoms unless they become infected. An infected cyst can cause:
- Fever
- Pain in the lower belly
- Pain when urinating
- A lump in the belly
- Urinary tract infection
Please note there are many conditions with symptoms similar to urachal cysts. It’s important to see your child’s doctor for proper diagnosis and treatment.
What causes urachal cysts?
A urachal cyst can occur when a sac or fluid or air develops in the urachus. While the urachus usually disappears after birth, a part of the urachus can remain in some people.
How are urachal cysts treated?
Not all urachal cysts need treatment. In some cases, your child’s doctor may suggest watching the cyst instead of treating it. If treatment is needed, it involves removing the cyst with surgery. Whenever possible, our surgeons at Connecticut Children’s perform this surgery laparoscopically, using minimally invasive techniques.
