评价经导管动脉栓塞术治疗对恶性肿瘤导致的急性膀胱出血的临床疗效。

回顾性分析2008年1月～2011年12月应用介入栓塞治疗恶性肿瘤导致的急性膀胱出血的42例患者临床资料，对栓塞术后血尿控制、并发症状况进行分析。

技术成功率100%（50/50），35例患者术后1~6天血尿停止或减少，近期成功率83.33%（35/42）。10例患者在随访期间再次出现血尿症状，远期成功率为76.19%(32/42)，无误栓、膀胱坏死、肾功能损伤等严重并发症发生。

经导管动脉栓塞术治疗恶性肿瘤急性膀胱出血疗效确切，安全有效。

To evaluate the clinical effect of transcatheter arterial embolization in treating acute bladder hemorrhage of malignant tumor patients.

Clinical data of transarterial embolization in 42 malignant tumor patients with bladder hemorrhage were analyzed retrospectively. Post-embolization angiography findings including bleeding control and complications were assessed.

The technical success rate was 100% (50/50). Hematuria was controlled after the first procedure (1 day to 6 days after embolization) in 35 of 42 patients, the recent successful rate was 83.33% (35/42). The late clinical success rate was 76.10% (32/42) since late bleeding recurrence was reported in 10 patients during the follow-up. No major complications related to embolization occurred, such as buttock or perineal pain, bladder necrosis, renal function damage etc.

Selective transcatheter arterial embolization is an effective and safe method to control acute bladder bleeding in malignant tumor patients. It can be used as priority selection.
