Bottom Line: The increased use of laparoscopic nephrectomy and nephron-sparing surgery has prompted the need for a more detailed radiological evaluation of the renal vascular anatomy.Multidetector CT angiography is a fast and accurate modality for assessing the precise anatomy of the renal vessels.In this pictorial review, we present the multidetector CT angiography appearances of the normal renal vascular anatomy and a spectrum of various anomalies that require accurate vascular depiction before undergoing surgical treatment.

ABSTRACT
The increased use of laparoscopic nephrectomy and nephron-sparing surgery has prompted the need for a more detailed radiological evaluation of the renal vascular anatomy. Multidetector CT angiography is a fast and accurate modality for assessing the precise anatomy of the renal vessels. In this pictorial review, we present the multidetector CT angiography appearances of the normal renal vascular anatomy and a spectrum of various anomalies that require accurate vascular depiction before undergoing surgical treatment.

Figure 1: Normally seen CT anatomy and relationship of renal vessels in 40-year-old female. Axial maximum intensity projection image shows bilateral renal veins (arrowheads) lying anterior to renal arteries (thin arrows).

Mentions: Most individuals have single renal arteries on either side that originate from the abdominal aorta at the level of the L2 vertebra (6) (Fig. 1). The right renal artery has a long downward course due to the inferior position of the right kidney and it lies behind the inferior vena cava (IVC). Classically, each kidney has a single renal vein that usually lies anterior to the renal artery at the renal hilum (Fig. 1). The left renal vein is longer than that of the right renal vein and the left renal vein measures 6-10 cm in length. It normally courses between the superior mesenteric artery and the abdominal aorta and then it joins the medial aspect of the IVC. The right renal vein has a short course, measuring 2 to 4 cm in length, and it joins the lateral aspect of the IVC. Unlike the right renal vein, the left renal vein receives several tributaries, which include an adrenal vein superiorly, a gonadal vein inferiorly and a lumbar vein posteriorly (6) (Fig. 2). Tributaries of the left renal vein, and especially the posterior lumbar branches, are of potential surgical importance if they are noted to be enlarged. The left kidney is preferred for laparoscopic donor nephrectomy due to the longer renal venous pedicle; however, a right nephrectomy may be performed if complex vascular anatomy precludes resection of the donor's left kidney (8).
