B-mode ultrasonic guidance was used to perform 76 percutaneous renal biopsies. Renal tissue was obtained from 73 (96.1%) subjects with adequate tissue for interpretation or diagnosis in 72 instances. Major bleeding complications occurred in four (5.3%) patients. Ultrasound has proved to be a safe and effective means of guiding physicians performing renal biopsies. In addition, it has many advantages over other techniques.
