An 8-year-old boy with infected urachal cyst presenting with macroscopic hematuria, pain on urination and high fever attack is reported. He had recurrent episodes of cystitis. At admission, a quail-egg sized solid tumor was palpated in the midline of his lower abdomen. The urine was infected. Ultrasonographic examination revealed an oval tumor 2 x 2.7 cm in diameter at the dome of the bladder with a thin funicular structure running toward the umbilicus. Cystoscopy revealed a round tumor covered with hyperemic epithelia. Transurethral biopsy revealed no malignant lesions of the epithelia. Partial cystectomy with excision of the funicular urachal ligament was performed. The pathological findings were consistent with persistent urachus with chronic inflammation. We reviewed 210 cases of infected urachal cysts reported in the Japanese literature.
报告了一名8岁男孩，患有感染性脐尿管囊肿，出现肉眼血尿、尿痛和高热发作。他有复发性膀胱炎病史。入院时，在其下腹部中线可触及一个鹌鹑蛋大小的实性肿瘤。尿液被感染。超声检查显示膀胱顶部有一个直径2×2.7 cm的椭圆形肿瘤，有一条细索状结构朝向脐部延伸。膀胱镜检查发现一个圆形肿瘤，表面上皮充血。经尿道活检显示上皮无恶性病变。行部分膀胱切除术并切除脐尿管索状韧带。病理结果与伴有慢性炎症的持续性脐尿管相符。我们回顾了日本文献中报道的210例感染性脐尿管囊肿病例。
