化膿性尿膜管嚢胞の3例

Abstract

Urachal disorder is a rare disease. Three cases of an infected urachal cyst are reported. Case I, a 49-year-old female was admitted to our hospital because of an abscess at the umblicus. Case II, a 28-year-old male, and case III, a 65-year-old male had a lower abdominal mass with fever and urinary frequency. The main symptom in all 3 cases was infectious. In all 3 cases, total removal of the cyst with the dome of urinary bladder was performed. The pathological findings of the specimens revealed chronic inflammatory granuloma. Usually, the abscess of the infected urachal cyst is covered with a thick wall of granuloma because of chronic progress. In spite of the rare possibility of peritoneal perforation, complete removal of the urachal cyst with partial cystectomy is the best treatment because of the high recurrence rate.
