What Is Perinephric Stranding? Dr. David Schulsinger explains that perinephric fat stranding is a hazy appearance in a linear pattern in the soft tissues in the perinephric space on a computed tomography image. The perinephric space, explains Aizenstein et al. is a cone-shaped compartment that contains the kidney, adrenal glands and perinephric ...

CT is also the best modality for fully evaluating the secondary signs of renal inflammatory disease and its complications. These signs include focal or global enlargement of the kidney, perinephric stranding, thickening of Gerota fascia, and abscess formation (, Fig 13,) (, 11,, 17,, 20,, 26,, 27).

Fluid collections around the kidneys on cross-sectional imaging may be caused by urine, blood, pus, lymph, or plasma. Ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) can not only show and characterize the fluid, but also may help determine the underlying cause of the perinephric fluid collection, such as ureteric obstruction, kidney injury, infection, or ...

Renal abscess forms a walled-off cavity; perinephric abscess consists of a more diffuse liquefaction located between the renal capsule and Gerota’s fascia. Septation of the perinephric abscess is frequent, which makes drainage more difficult than that of renal abscess.

Secondary signs of obstructive uropathy, including hydronephrosis, perinephric and periureteral stranding, as well as ureterectasis, are well demonstrated on CT. [15, 14] Several reports compared unenhanced helical CT with intravenous urography (IVU), the established criterion standard in evaluating the genitourinary system.
