Kidney Vein Artery Ureter. The transitional epithelium may appear as a layer of column shaped cells when relaxed and of flatter cells when distended. The kidney is surrounded by tough fibrous tissue the renal capsule which is itself surrounded by perirenal fat renal fascia and.
Below the epithelium sits the lamina propria the lamina propria is made up of loose connective tissue with many elastic fibers interspersed with. The ureter begins its descent to the bladder by running along the medial aspect of the psoas muscle here the ureter lies anteriorly and slightly medial. Developmental anomalies of the kidneys and ureters are numerous and not only potentially render image interpretation confusing but also in many instances make the kidneys more prone to pathology.
At the concave medial margin of each kidney is a vertical cleft the renal hilum where the renal artery enters and the renal vein and renal pelvis leave the renal sinus.
The ureter renal pelvis renal artery renal vein lymphatic vessels and nerves enter or exit through the renal hilum the kidney. As long as they both enter the bladder normally this duplicated collecting system is not a problem. Developmental anomalies of the kidneys and ureters are numerous and not only potentially render image interpretation confusing but also in many instances make the kidneys more prone to pathology. The kidney is a bean shaped structure with a convex and a concave border.
