Objective To evaluate the clinical application of superselective renal artery embolization in the treatment of iatrogenic renal hemorrhage. Methods The iatrogenic renal hemorrhage in fifteen patients was first demonstrated by renal arterigraphy to diagnose the rupture site and degree of injury. And then they were treated by percutaneous catheterized superselective renal arterial embolization through guidance of guide wire. Results In all 15 patients, the occlusive ruption of bleeding arteries and disappearance of extravasation staining were found after the superselective catheterized renal arterial embolization. Clinically, the bloody urine turned clear without macroscopic hematuria during 1-3 days in all patients after the procedure. Conclusions Superseclective renal arterial embolization treatment signified a less invasion, less complications, good hemostatic efficacy, and maximal preservation of renal tissue and function for iatrogenic renal hemorrhage. The treatment is worthy to be recommended.%目的 探讨超选择性肾动脉栓塞治疗医源性肾损伤的临床应用价值.方法 15例医源性肾损伤患者,首先行数字减影肾动脉造影,明确肾动脉破裂或损伤的部位及程度,在导丝引导下用吸收性明胶海绵颗粒进行超选择性插管栓塞治疗.结果 15例患者经数字减影肾动脉造影后均可明确肾动脉出血部位,经超选择性插管吸收性明胶海绵颗粒栓塞后均能有效止血,栓塞后造影显示出血动脉中断闭塞,造影剂外溢消失,术后1～3 d肉眼血尿消失.结论 超选择性肾动脉栓塞治疗医源性肾损伤定位准确、止血迅速、创伤小、并发症较少,能最大限度地保护肾功能,是治疗医源性肾损伤出血的有效方法.
