Perinephric stranding is probably the manifestation of increased pressure in the collecting system in the early phase of ureteral obstruction. Stranding of perinephric fat is defined as linear areas of soft tissue attenuation in the perinephric space, which can result from any acute process or injury to the kidney. When unilateral perinephric stranding is identified it is most frequently the result of calyceal rupture or perinephric inflammation. Perinephric stranding is probably the manifestation of increased pressure in the collecting system in the early phase of ureteral obstruction.
The potentiometric surface is an imaginary surface above the aquifer, to which water from an artesian aquifer would rise in a pipe. The term potentiometric surface means head- or potential-indicating surface and is preferable to the term piezometric surface, which is found in some literature.
