Double right renal vein: clinical and surgical implications and review of the literature

Abstract

Context: Variations in renal vascular morphology are relatively common and involve both the renal arteries and the renal veins. Presence of supernumerary vessels is the variation most frequently encountered. Knowledge of such findings is valuable for urologists with regard to kidney transplantation, nephrectomy, vascular anastomosis, selective catheterization and many other surgical procedures on the kidneys. Objective: To report on a case of duplication of the right renal vein and its clinical and surgical implications. Case report: In one dissected specimen from a male cadaver, the presence of two right renal veins parallel to each other was observed in a position anteroinferior to the right renal artery. One vein emerged from the upper portion of the renal hilum, while the other emerged from the lower portion of the hilum. The two veins drained separately into the inferior vena cava, and neither of them received any tributaries. Conclusion: Knowledge of these vascular variations is important for urologists, vascular surgeons and radiologists, given that performing angiography prior to surgical interventions in the retroperitoneal space avoids complications, especially with regard to kidney transplantation.

Multiple Renal Vessels: A Case Report

“…Anatomical variations of renal arteries and veins are often reported in several studies [5,6,9,10], as well as case reports of duplicity and triplicity [12][13][14][15][16]. In the present study there were found triple renal arteries on the left kidney and double renal veins on the right kidney.…”

Double Bilateral Renal Artery in Human Fetus

“…variation of renal arteries is extremely important for the vascular clinic and imageologists [3]. The accessory renal arteries range from 18.3% and 36.1% of the cases, on the right side the variation is from 11 to 16% and on the left side from 10 to 23%, and in both sides it can get to 5% [1,4,5,8]. In our study, two double bilateral renal arteries were found.…”

“…Among all its anatomical variations one of the most common is the presence of additional renal arteries [4,5]. This occurrence can become a complicating factor in renal surgeries, and particularly in kidney transplants [4].…”
