A 31-year-old Japanese man visited our department with macroscopic hematuria. He had stayed in Asia, Middle East and Africa during the past several years. He was diagnosed with urinary schistosomiasis because examination of urine and a biopsy specimen of the bladder mucosa revealed Schistosoma haematobium ova. Cystoscopy revealed granulomatous lesions and polypoid patches at the right ureteral orifice, posterior wall and dome of the bladder. Radiological examination showed no obstructive uropathy. Histologically, moderate to severe urothelial dysplasia was found but without evidence of malignancy. The disease has been under good control following treatment with praziquantel. Today international exchange between Japan and other countries is common. Therefore, physicians should consider the possibility of schistosomiasis in patients who have been to endemic areas.
一名31岁的日本男性因肉眼血尿前来我科就诊。他在过去几年中曾旅居亚洲、中东和非洲。由于尿液检查及膀胱黏膜活检标本发现埃及血吸虫卵，他被诊断为泌尿生殖系统血吸虫病。膀胱镜检查发现右侧输尿管口、膀胱后壁及顶部有肉芽肿性病变和息肉样斑块。影像学检查未显示梗阻性尿路病。组织学检查发现中度至重度尿路上皮发育异常，但无恶性证据。吡喹酮治疗后病情得到良好控制。如今日本与其他国家之间的国际交流很普遍。因此，医生应考虑去过流行地区的患者感染血吸虫病的可能性。
