Perirenal space

Dr Henry Knipe and Dr Jeremy Jones et al.

The perirenal space is the largest of the three areas in the retroperitoneum and is the most easily identified. It contains the kidneys, renal vessels and proximal collecting systems, adrenal glands and an adequate amount of fat to allow identification on CT scanning.

The space is surrounded by the perirenal fascia and is in continuity with the opposite perirenal space across the midline. It abuts the bare area of the liver on the right and the subphrenic space on the left; there is mediastinal communication via the various diaphragmatic hiatus.

In disease, the space is usually closed inferiorly, preventing pelvic spread.
