Kidneys

Description

Centered in the posterior abdomen, the paired kidneys appear as retroperitoneal, bean-shaped organs flanking the vertebral column, with the right kidney seated slightly inferior to the left in relation to the liver. At each medial border, the renal hilum faces anteromedially, where the renal artery enters and the renal vein exits before the renal pelvis narrows into the ureter. The ureters descend inferiorly from the renal pelvis along the psoas margin toward the pelvis, while adjacent viscera are faintly visible through the transparent torso overlay, including liver superior-right and bowel loops more anteriorly. Renal morphology and the orientation of the hilum matter when you teach or plan around the retroperitoneal space. Percutaneous nephrostomy and posterior approaches for nephrolithiasis rely on appreciating that the collecting system lies more posterior than the renal vasculature at the hilum, and that the kidneys sit deep to the posterior abdominal wall musculature rather than within the peritoneal cavity. A clear sense of the kidneys’ position relative to the spine and upper abdominal organs also supports interpretation of flank pain patterns and the typical inferior course of ureteric calculi. Use this plate in gross anatomy or urogenital blocks to anchor organ topography in a male torso, and in surgical, urologic, or radiology teaching materials that need an uncluttered overview of kidneys, renal vessels, and ureteral continuity without isolating the organs from surrounding context.
