Newer variants of retroaortic left renal vein

Abstract

The left renal vein (LRV) passing behind the abdominal aorta is termed as a retroaortic LRV (RLRV) and it is a relatively uncommon condition. Since the left kidney is preferred in the setting of live donor kidney transplantation, urologists must be familiar with the anomalies of the LRV. There are four variants of RLRV mentioned in the literature. However, we came across two newer variants of RLRV in two donors for renal transplantation. Both donors underwent successful left donor nephrectomy.
