CT guided renal biopsy

Case contributed by Dr Ian Bickle


25 year-old with nephrotic syndrome and normal ultrasound kidneys.

Patient Data

Age: 25 years old
Gender: Female

The patient's body habitus did not permit ultrasound guided biopsy.

The steps for CT guided renal biopsy:   skin surface markers to choose site, following by infiltration needle and co-axial needle position prior to biopsy.

Case Discussion

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.
