Objective To Explore the curative effect and safety of intervention embolization treating for renal hemorrhage after percutaneous nephrolithotomy. Methods From January 2007 to December 2012, intervention embolization for 109 cases with renal hemorrhage after percutaneous nephrolithotomy was performed in the intervention department of the affiliated Yan'an hospital and intervention department of the 2nd affiliated hospital of Kunming Medical University. The therapeutic effects were reviewed. Results 95 cases of 109 cases renal arteriography have found abnormal signs, including contrast medium spillover 52 cases, contrast medium spillover and pseudo aneurysm 10 cases, arteriovenous fistula and pseudo aneurysm 2 case, pseudoaneurysm 26 cases, the pseudoaneurysm with arteriovenous fistula 1 cases, and simple arteriovenous fistula 4 cases. They were performed with embolism hemostatic technique, and all cases were successfully completed. 14 cases with no bleeding signs were treated with intervention perfusion hemostatic of thrombin, and 9 cases were successful. The success rate of operation was 95.4%. There was no recurring hemorrhage in renal in the 1 to 24 months follow-up. Conclusion Intervention embolization treating for renal hemorrhage after percutaneous nephrolithotomy has the advantages of safety, small trauma, effectiveness, good prognosis, stopping bleeding quickly, less complications, quick recovery, etc. It is worth popularizing and applying in the clinic practice.

Objective The purpose of this study was to evaluate superselective renal arterial embolization (SRAE) in treating severe renal hemorrhage after mPCNL. Methods SRAE was performed in 287 patients with severe renal hemorrhage after mPCNL by using Seldingers method. Using coil and PVA microspheres or coil and gelatin foam, renal arterial embolization was performed. Before embolization, the renal artery angiography could judge the region and degree of arterial injury. Results Two hundred and eighty-two patients artery angiography were positive, and 5 patients artery angiography were negative. After SRAE with single session, the hemorrhage stopped in 257 patients. 26 patients had a recurrence of hematuria, and the blood urine subsided after SRAE was employed again. The blood urine subsided in 1 patient after the third embolization. 3 patients still bled after renal embolization and had to receive surgery. The 6-12 months follow-up was carried out in all patients. There was no haematuia relapses or pyonephrosis occurring. After nephrectomy, blood pressure of 1 patient with a long term hypertension and renal atrophy returned to normal. Conclusion Superselective renal artery catheterization and embolization can maximally preserve renal function and save lives, is a rapid and safe treatment for severe renal hemorrhage after mPCNL. It can provide an effective guarantee for the development of mPCNL. [ABSTRACT FROM AUTHOR]
