Application of super-selective renal artery embolization in renal injuries

OBJECTIVE: To use super-selective renal artery embolization in treatment of patients with renal injuries. METHODS: From 1991 to 1998, 11 cases of renal injuries due to d ifferent causes underwent super-selective renal artery embolization. In these p atients, 91% of injury sites were segmental arteries and their branches. All the patients were treated with steel coil for embolization. RESULTS: Nine patients showed prompt cessation of hematuria, an d in 2 patients hematuria stopped 2-4 days after embolization. CONCLUSIONS: Super-selective renal artery embolization (SSRAE) is suitable for severe hematuria, limited size of kidney injuries, stable hemod ynamic parameters after conservative treatment and low reserve of renal function. Steel coil is an effective embolic material, rapid hemostasis can be fulfilled and renal function can be reserved. Super-selective renal artery embolization has low incidence of complications and can shorten hospitalization time.
