Umbilical-urachal sinus

Umbilical-urachal sinus is a rare congenital anomaly that occurs when the urachus, a tube that connects the bladder to the umbilicus (belly button) in the developing fetus, fails to obliterate after birth. This condition can lead to various complications such as infection, abscess formation, and even malignancy.

Anatomy

The urachus is a structure that is present during fetal development. It connects the bladder to the umbilicus and allows urine to be expelled from the fetus into the amniotic fluid. After birth, the urachus normally obliterates and becomes a fibrous cord known as the median umbilical ligament. However, in some cases, the urachus fails to obliterate completely, leading to the formation of an umbilical-urachal sinus.

Symptoms

The symptoms of an umbilical-urachal sinus can vary depending on the extent of the urachal remnant and the presence of complications. Common symptoms include:

• Umbilical discharge: This is often the first sign of an umbilical-urachal sinus. The discharge may be clear, cloudy, or bloody.
• Abdominal pain: This can occur if the sinus becomes infected or if an abscess forms.
• Fever: This is a common sign of infection.
• Urinary symptoms: These can include frequency, urgency, and pain during urination.

Diagnosis

The diagnosis of an umbilical-urachal sinus is often made based on the clinical symptoms and physical examination findings. Imaging studies such as ultrasound or CT scan may be used to confirm the diagnosis and to assess the extent of the urachal remnant.

Treatment

The treatment of an umbilical-urachal sinus typically involves surgical removal of the urachal remnant. This is usually done through a procedure known as a urachectomy. Antibiotics may also be given to treat any associated infection.

Prognosis

The prognosis for individuals with an umbilical-urachal sinus is generally good, especially if the condition is diagnosed and treated early. However, there is a small risk of complications such as infection, abscess formation, and malignancy.
