超选择性肾动脉栓塞术治疗经皮肾镜取石术后出血的效果评价

Evaluation on effect of superselective renal artery embolization in treating hemorrhage after pereutaneous nephrolithotomy

目的 探讨超选择性肾动脉栓塞在经皮肾镜取石术（PCNL）后严重肾脏出血中的应用价值.方法 回顾性分析PCNL术后严重出血并采用Seldinger技术行股动脉穿刺插管进行超选择性肾动脉栓塞治疗的31例患者的临床资料,分析其治疗效果及并发症.结果 患者超选择性肾动脉栓塞治疗术后2～4 d肉眼血尿消失,均无严重并发症发生.随访1～24个月无肾出血复发,肾功能恢复正常.结论 对于PCNL术后并发严重肾脏出血者,超选择性肾动脉栓塞是一种安全有效的治疗方法.

Objective To evaluate the application value of superselective renal artery embolization in severe renal hemorrhage after percutaneous nephrolithotomy（PCNL）. Methods The clinical data of 31 cases of severe renal hemorrhage after PCNL and superselective renal artery embolization by adopting the Seldinger technique for conducting femoral artery puncture and intubation were analyzed retrospectively. Its therapeutic effect and complications were analyzed. Results Gross hematuria disappeared in all cases within postoperative 2-4 d. No serious complications occurred. No renal hemorrhage reoccurred during 1-24 months follow up. The renal function recovered to normal. Conclusion Superseleetive renal artery embolization is an effective and safe way to treat severe renal hemorrhage after PCNL.
