A urachal cyst is a sinus remaining from the allantois during embryogenesis. It is a cyst which occurs in the remnants between the umbilicus and bladder.〔http://www.wrongdiagnosis.com/medical/urachal_cyst.htm〕 This is a type of cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterized by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus.〔 Urachal cysts are usually silent clinically until infection, calculi or adenocarcinoma develop. ==Symptoms== * Lower abdominal pain * Pain on urination * Persistent umbilical discharge * Fever * UTI (Urinary Tract Infection) * Lump * Hematuria 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Urachal cyst」の詳細全文を読む スポンサード リンク
