Calculi (stones) of the kidneys and ureters may be detected by ultrasound. A kidney ultrasound may be performed to assist in placement of needles used to biopsy (obtain a tissue sample) the kidneys, to drain fluid from a cyst or abscess, or to place a drainage tube.
Why It Is Done. A kidney biopsy is done to: 1  Find kidney disease when there is blood or protein in the urine or when the kidneys are not working well. 2  Check kidney problems seen on an ultrasound or a CT scan. 3  Watch kidney disease and see if treatment is working.  Find out why a transplanted kidney isn't working well.
