目的 探讨超选择性肾动脉栓塞术治疗肾损伤的适应证、优点及注意事项。方法 采用超选择性肾动脉栓塞术治疗 2 0例肾损伤患者 ,其中外伤性肾损伤 13例 ,复杂性肾结石取石手术和体外冲击波碎石术后肾损伤 7例。 结果 10例患者于术后第 1天肉眼血尿消失 ;6例于术后第 4天消失 ;3例于术后第 5天第 2次栓塞术后血尿消失 ;1例栓塞术后仍有持续性血尿加重而行肾切除术。 结论 超选择性肾动脉栓塞术具有侵袭小、止血效果好、能最大限度保护肾功能、并发症少等优点 ,是一种治疗轻、中度肾损伤的安全有效的方法。
Objective To investigate the indications, advantages and precautions of super selective renal artery embolization in the treatment of renal injury. Methods Superselective renal artery embolization was used to treat 20 patients with renal injury, including 13 cases of traumatic renal injury, 7 cases of complicated renal stone surgery and 7 cases of renal injury after extracorporeal shock wave lithotripsy. Results The gross hematuria disappeared in 10 patients on the first postoperative day, 6 disappeared on the 4th postoperative day, 3 hematuria disappeared after the 2nd embolization on the 5th postoperative day, and 1 persisted after the embolization Hematuria increased nephrectomy. Conclusion Superselective renal artery embolization is a safe and effective method for the treatment of mild to moderate renal injury with less invasion, better hemostatic effect, maximum protection of renal function, fewer complications and so on.
