Urachal fistula

Urachal fistula is a rare condition that occurs when the urachus, a tube that connects the bladder to the umbilical cord in fetal development, fails to close after birth. This can lead to a variety of symptoms and complications, including infection and abdominal pain.

Symptoms

The most common symptoms of a urachal fistula include:

• Abdominal pain
• Fever
• Urinary tract infection
• Discharge from the umbilicus

Causes

The exact cause of a urachal fistula is unknown, but it is believed to be due to a failure of the urachus to close completely after birth. This can result in a connection between the bladder and the umbilicus, allowing urine to pass through and potentially leading to infection.

Diagnosis

Diagnosis of a urachal fistula can be challenging due to its rarity and the nonspecific nature of its symptoms. However, several diagnostic tests can be used, including:

• Ultrasound
• Computed tomography (CT) scan
• Magnetic resonance imaging (MRI)
• Cystoscopy

Treatment

Treatment for a urachal fistula typically involves surgery to remove the fistula and any associated abscesses or tumors. Antibiotics may also be prescribed to treat any underlying infections.

Prognosis

With appropriate treatment, the prognosis for individuals with a urachal fistula is generally good. However, complications can occur, including recurrent infections and the development of urachal carcinoma, a rare form of bladder cancer.
