In a 48-year-old man with dysuria and microscopic haematuria, pyelography, cystoscopy and bimanual bladder palpation showed no definite abnormality. Because of continued symptoms, ultrasound scanning of the abdomen was done three months later. The examination revealed a tumour in close relation to the top of the bladder. Malignant cells were aspirated at ultrasonically guided puncture, and a urachus tumour was suspected. For early diagnosis of urachus tumours, ultrasound investigation of vague bladder symptoms is required.
一名48岁男性，有排尿困难和镜下血尿症状，肾盂造影、膀胱镜检查及双手触诊均未发现明确异常。由于症状持续存在，三个月后进行了腹部超声检查。检查发现一个与膀胱顶部关系密切的肿瘤。在超声引导下穿刺抽吸到恶性细胞，怀疑为脐尿管肿瘤。对于脐尿管肿瘤的早期诊断，对于不明原因的膀胱症状进行超声检查是必要的。
