- Abstract
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.
