Kyste de l’ouraque

Overview 

Urachal Cyst Disease is a rare condition that occurs due to incomplete closure of the urachus, a fetal structure that connects the bladder to the umbilical cord during development. Normally, the urachus closes before birth, but if a part remains open, it can form a fluid-filled cyst.

In many cases, a urachal cyst remains asymptomatic. However, when infected or enlarged, it can cause discomfort and complications, requiring medical evaluation and treatment.

Types of Urachal Cyst

• Urachal Cyst: Fluid-filled cavity within the urachus
• Patent Urachus: Complete opening between bladder and umbilicus
• Urachal Sinus: Opening at the umbilical end
• Vesicourachal Diverticulum: Opening at the bladder end

Symptoms of Urachal Cyst

• Lower abdominal pain
• Tenderness around the navel
• Swelling or lump near the belly button
• Fever (if infection occurs)
• Redness or discharge from the umbilicus
• Pain during urination
• Urinary tract infections

Causes of Urachal Cyst

• Incomplete closure of the urachus during fetal development
• Infection of the cyst
• Bacterial contamination
• Congenital abnormalities

Complications of Urachal Cyst

• Infection or abscess formation
• Rupture of the cyst
• Recurrent infections
• Spread of infection to surrounding tissues
• Rare risk of urachal cancer

Risk Factors of Urachal Cyst

• Congenital urachal abnormalities
• Male gender (slightly more common)
• Poor hygiene (in case of infection)
• Untreated cyst

Prevention of Urachal Cyst

• Early diagnosis and monitoring
• Maintain proper hygiene
• Prompt treatment of infections
• Regular medical check-ups if diagnosed early
