The topic Alternating Urachal Sinus you are seeking is a synonym, or alternative name, or is closely related to the medical condition Alternating Sinus of Urachus.

Quick Summary:

• The urachus is a tubular structure that forms during early fetal development. This structure connects the anterior portion (anterior bone) of the urinary bladder to the umbilicus. Usually, the urachus closes by week 12 of gestation, leaving behind a thick fibrous band. However, rarely, some portions of the urachus may not close completely, resulting in a variety of urachal abnormalities
• Alternating Sinus of Urachus occurs when the urachus fails to completely seal at both ends i.e., either at the umbilicus or at the urinary bladder, such that it causes the periodic discharge of infected fluid contents at either ends alternatively. This condition is extremely uncommon
• Even though Alternating Sinus of Urachus is a congenital occurrence; in many cases, it may remain symptomless and thus, may be undiagnosed throughout one’s life. When symptoms develop, they are known to do so frequently in childhood than adulthood
• The signs and symptoms of Alternating Sinus of Urachus often arise due to infection and may include fluid discharge from the umbilicus and abdominal pain. There is an elevated risk for recurrent infections in some cases
• In rare cases, symptomatic Alternating Sinus of Urachus may be surgically resected, either through an open approach or a laparoscopy. The prognosis of children with isolated urachal anomalies (i.e., not associated with any other congenital conditions) is typically good with adequate treatment

There are five forms of congenital urachal remnant abnormalities, and these include:

• Alternating Sinus of Urachus (some experts recognize this as a type of umbilical-urachal sinus)
• Patent urachus
• Umbilical-urachal sinus
• Urachal cyst
• Vesicourachal diverticulum

Among these urachal abnormalities, patent urachus is the only condition that predominantly presents symptoms following birth of the child (early infancy).
