CT guided non-focal renal biopsy for assessment of intrinsic renal pathology.
Ultrasound is most commonly used as truly dynamic and non-radiation required.
In larger patients CT guidance is required.
Note the angulated approach from the lateral position to prevent traversing paraspinal muscle.
As two cores are required, a co-axial needle - usually 18G - is used.
The other cortex is particularly targeted to acquire a large number of glomeruli.
