Perirenal Space

8 11 until now most anatomical and radiological studies of the superior adherence of the renal fascia in retroperitoneal space employed the sectional anatomy on cadavers the contrast medium injection of the cadaveric.

Perirenal space. Identification of their specific localization may be very important in the clinical diagnosis and in determining the most appropriate therapy. Some scholars believed that the perirenal space ps opens upwards 1 7 while others supported that the ps is upwardly closed. Fluid dissecting between fascial planes in the perinephric space is seen in patients with pancreatitis. Although many researchers have studied through different methods the superior communications among these spaces there are still controversies.

The perirenal spaces communicate with one another at the level of the lower lumbar vertebrae. Abscesses or hematomas in the perirenal space and in the subcapsular region of the kidney can simulate each other and a host of other conditions closely. The perirenal spaces communicate with one another at the level of the lower lumbar vertebrae. The perirenal space is the largest of the three divisions of the retroperitoneum and is the most easily identified.

The perirenal space has the shape of an inverted cone and contains the kidneys adrenal glands and related vasculature. The perirenal space because of its perforating capsular vessels and lymphatics may be a site for the metastatic deposits of many malignant conditions. Superiorly the perirenal space is open to the bare area of the liver. Superiorly the perirenal space is open to the bare area of the liver.

The anterior pararenal space is the portion of the retroperitoneum that lies between the posterior surface of the parietal peritoneum and the anterior reflection of the perirenal fascia. The left or right kidney may be affected depending on whether the inflammatory fluid tracks from the tail or the head and neck of the pancreas respectively 6. Common sources of perirenal metastatic disease include melanoma lung breast renal cell or transitional cell carci noma 189 259 fig. It is delineated by the anterior and posterior renal fasciae which surround the ureter and allow communication towards the pelvis.

It also contains the perinephric bridging septa of kunin 5. The hallmark of perirenal. Chronic urinoma appears as an encapsulated cystic mass often aligned parallel with the perirenal space. The retroperitoneal space retroperitoneum is the anatomical space sometimes a potential space in the abdominal cavity behind retro the peritoneum.

The hallmark of perirenal infection is localized or diffuse gas.
