Abstract Objective: To evaluate the clinical value of selective renal artery embolization for renal carcinoma, symptomatic renal angiomyolipoma and traumatic renal hemorrhage. Methods: Selective renal artery embolization was performed in 68 patients via femoral artery with Seldinger technique, 30 cases were embolized with gelatin sponge chips before operation for renal carcinoma, and 8 cases were embolized with MMC and iodized oil, and gelatin sponge for palliative treatment of advanced renal carcinoma, 6 cases were embolized with thread segments for symptomatic renal angiomyolipoma, 24 cases were embolized with self blood coagulum, gelatin sponge and/or steel coils for traumatic renal hemorrhage. Results: In renal carcinoma, after renal artery embolization during operation, less bleeding, less operation time because of clear operation field. Clinical symptoms were improved obviously 1~3 weeks after treatment, and the tumor mass was decreased evidently with an average shrinkage of 65.6%, 3 months after embolization in symptomatic renal angiomyolipoma and advanced renal carcinoma for palliative treatment. The hemorrhage had been successfully controlled by means of renal artery embolization, and the renal function was maintained as much as possible. No severe complications occurred after embolization in all the patients. Conclusion: As a minimal invasive technique, selective renal artery embolization is a safe and effective method with less complication for treatment as an adjuvant pre-operative therapy for renal carcinoma or a palliative treatment for advanced carcinoma and an effective treatment for symptomatic renal angiomyolipoma and traumatic renal hemorrhage. Renal artery embolization should be widely applied for these renal diseases.
