What is perinephric space?

The perinephric space, also known as the perirenal space, is the area surrounding the kidneys, encapsulated by the renal fascia. It contains fat and connective tissue, providing cushioning and support to the kidneys. This space is significant in the context of renal diseases and conditions, as infections or tumors can spread within it, affecting the surrounding structures. It is also important in surgical procedures involving the kidneys, as it helps delineate the boundaries for dissection.
