Hi doctors, can you tell me what is involved in a prostate biopsy?

Here are...: Bowel prep to keep rectum empty so to avoid sound transmission; take antibiotics timely; do urinalysis to make sure of no active UTI; insert ultrasound probe through anus into rectum while hip in full flexsion (usually in lateral position); Doc will visualize the shape and texture of prostate tissue to selectively or randomly obtain small piece of tissue (1 x 20 mm) with special needle under aneth
