RESUMO
Objective To assess the value of selective renal arteriography and embolization in the therapy of nephrorrhagia diseases.Methods Fifteen patients of renal hemorrhages including 10 iatrogenic renal trauma,3 renal harmatoma and 2 renal closed injury with ineffective medical treatment underwent selective renal artery embolization.Results Renal artery an-giographies confirmed renal segmental arteries and/or their branches injuries.Gelatin sponge,PVA or steel coil were used for embolization.During 1-3 months fllowing-up,renal abscess was found in 2 patients without superselective embolization,while haematuria occurred in one case after embolization with gelatin sponge but stopped after medical treatment.The renal function of all patients were normal after embolization.Conclusion Superselective renal artery embolization has reliable effect and slight complication in the treatment of nephrorrhagia,especially suitable for patients after surgery and renal inadequacy.
