Three cases of renal artery aneurysm are presented.
One of the 3 cases showed a renal artery aneurysm in a congenital solitary kidney. All the cases were successfully treated by ex vivo surgery (renal artery aneurysmectomy) and renal autotransplantation. The case of renal artery aneurysm in congenital solitary kidney resulted in acute renal failure postoperatively and required hemodialysis 9 times for 3 weeks. Thereafter, the renal function recovered completely. Excellent results were obtained also in the other 2 cases.
168 cases of renal artery aneurysm including our 3 cases have been reported in the Japanese literatures. Among those cases, renal artery aneurysm in congenital solitary kidney was noted only in 8 cases including the case reported here. As for the treatment, most of the reported cases were treated by in situ excision of the aneurysm or nephrectomy. There have been only 7 cases including the 3 cases of the our present series. We believe that the ex vivo surgery for renal artery aneurysm is not only useful for preservation of the postoperative renal function but also a safe and excellent procedure to remove the aneurysm situated in distal small branches of the renal artery.
