Abstract
With real-time ultrasound visualization and an automatic core biopsy system 23 percutaneous renal biopsies were performed with the use of local anesthesia in 22 patients. Adequate tissue for diagnosis was obtained in all 23 cases, with 1 patient undergoing bilateral renal biopsy and 1 requiring repeat biopsy. One patient had an asymptomatic perirenal hematoma and 1 experienced a single episode of transient gross hematuria. There were no major complications. The use of an automatic core biopsy system guided by real-time ultrasound is an important technique that may be added to the urological armamentarium.
