Abstract
Double renal artery in human cadavers: a case report
Highlights
The human kidney is a paired organ located posterior to the visceral peritoneum
Renal artery duplication is an anatomical variation, which is a normal flexibility of the topography and morphology in body structures
Several authors characterize it: the prevalence of multiple vessels occurs in approximately 20-50% of cases. This is an observational study; we aimed to describe the anatomical variations concerning the duplicity of the renal artery in human cadavers, focusing on possible implications to clinical and surgical procedures
Summary
The human kidney is a paired organ located posterior to the visceral peritoneum. At its medial edge, there is a vertical fissure called the renal hilum, composed by ureter, renal artery and vein, constituting the renal pedicles (FERREIRA et al, 2014; DIÉGUEZ et al, 2016).Bredel performed the first anatomical studies on renal vascular segmentation in 1901, confirming the findings from Hyrtl, in 1882. The first study of renal vascularization was conducted by Fue Berenger (1470-1530), and the acknowledgment of this anatomical data was credited to John Honter, in 1794 (SKANDALAKIS; McCLUSKY, 2006). These findings are of fundamental importance in the anatomical-clinical understanding of the anatomical variations of the urinary system. Renal artery duplicity can be defined as of normal flexibility in its topography and morphology, with no apparent functional changes (SANUDO; VAZQUEZ; PUERTA, 2003). This variation is, presumably, clinically silent, only being discovered when surgical procedures are needed, by imaging procedures and/or autopsy
