The left renal artery is dissected with endoscopic gastrointestinal anastomosis (endo-GIA) stapler, and the left renal vein
laterally (Figure 5).
 found left renal vein
duplication with the retroaortic branch trapped between the vertebral column and the aorta at the level of the aortic bifurcation .
[2,3] The right vena cava is usually dominant with the left vena cava joining it in front or behind the aorta at the level of or just above the left renal vein
.  In our case, the left vena cava was dominant.

After its origin, the testicular artery passed behind the left renal vein
and descended downward.
CT urogram showed right renal calculus in renal pelvis with retroaortic left renal vein
(RLRV type I), which was compressed to more than half of its diameter (fig-2).
In the block with bilateral variation, the accessory right renal artery is located anteriorly to the inferior vena cava; the accessory left renal artery is located anteriorly to a left renal vein
. This block has also variation in the renal veins, which is being described in another study.
However, the upper limit, up to the left renal vein
, is still debated, and technical aspects of PAL may differ depending on whether this procedure is the only one performed, or it is combined with other staging procedures for gynaecologic malignancies, such as pelvic lymphadenectomy, hysterectomy, omentectomy, and random peritoneal sampling.
The veins running along the septula and those of the tunica vasculosa converge on the posterior border of the testis where they form a dense plexus, called the pampiniform plexus (PP), which finally pours its blood through the TV, on the right side, into the inferior vena cava (IVC), on the left side, and into the left renal vein
However, incidentally an abnormal-appearing left renal vein
Left renal vein
is draining into the hypoplastic segment of IVC (Fig.
