Q: In otherwise routine cases, which part of the kidney is usually targeted for biopsy?



Answer: Lower pole

Kidney Biopsy is usually performed with patient in prone position with pillow underneath, and under ultrasound. The lower pole is targeted  as it minimize the chances of hitting any major vessel.
