Bladder metastases from remote primary sites are rarely reported. We present a case of haematuria caused by infiltrationof the urinary bladder wall by a nodule resulting from peritoneal dissemination of a primary gastric tumour.The nodule was detected by computed tomography, magnetic resonance imaging and cystoscopy. Transarterialembolization or haemostasis could not be performed because of the haematuria, thus the vesical bleeding was treatedwith a low irradiation dose of 3 Gy/fraction for a total of 30 Gy administered to the dome of the urinary bladder.No adverse effects occurred, and the gross haematuria and nodule resolved within 1 week. Thus, radiotherapyshould be considered for treatment of visceral bleeding caused by peritoneal dissemination of gastric cancer whenother methods of haemostasis cannot be performed.
来自远处原发部位的膀胱转移瘤鲜有报道。我们报告一例因原发性胃肿瘤腹膜播散形成的结节浸润膀胱壁导致血尿的病例。该结节通过计算机断层扫描、磁共振成像和膀胱镜检查得以发现。由于血尿无法进行经动脉栓塞或止血治疗，因此对膀胱顶部给予低照射剂量3 Gy/分次，总量30 Gy进行膀胱出血治疗。未出现不良反应，肉眼血尿和结节在1周内消退。因此，当无法采用其他止血方法时，对于胃癌腹膜播散引起的内脏出血应考虑放疗。
