Repeated subselective renal embolization following pyelolithotomy: angiographic salvage of a kidney

A bleeding intrarenal aneurysm secondary to pyelolithotomy was treated successfully by super-selective catheterization of the feeding arteries and embolization using stainless steel Gianturco coils. Three therapeutic procedures were performed because of recurrent hemorrhage. The advantages of this mode of treatment are that it is well tolerated, relatively safe and allows maximal preservation of functioning renal tissue.
