A 52-year-old woman complained of persistent discharge from an umbilicus which she had for 18 years. Abdominal X-ray showed a stone-like shadow measuring 5 x 3 cm at the 5th lumbar spine. Cystoscopic examination revealed a hole at the dome of the bladder and a ureteral catheter was inserted approximately 3 cm through the hole. Computerized tomography scan and magnetic resonance imaging demonstrated a cyst communicating to the umbilicus and bladder. The preoperative diagnosis was a patient urachus associated with stone. Urachal cyst containing a stone was removed and partial cystectomy was performed. The stone was a mixture of magnesium ammonium phosphate and calcium phosphate. Pathological examination showed no evidence of malignancy. More than 210 cases of urachal cyst have been reported in Japan. About 10% of the cases were associated with stones.
一名52岁女性主诉脐部持续排液18年。腹部X线显示第5腰椎水平有一个5×3 cm的结石样阴影。膀胱镜检查发现膀胱顶部有一个孔，通过该孔插入输尿管导管约3 cm。计算机断层扫描和磁共振成像显示一个囊肿与脐部和膀胱相通。术前诊断为脐尿管结石。切除含有结石的脐尿管囊肿并进行了部分囊肿切除术。结石为磷酸镁铵和磷酸钙的混合物。病理检查未发现恶性证据。日本已报道210多例脐尿管囊肿病例。约10%的病例与结石有关。
