A simple method for percutaneous renal biopsy.

A technique for percutaneous renal biopsy in children is described which combines the use of ultrasound guidance and a disposable automatic biopsy device. Twenty-five biopsies in 22 children were performed using the Bard Monopty biopsy instrument. Adequate tissue was obtained to aid in diagnosis in 24 of 25 cases. Complications inclused 2 small perinephric hematomas. We conclude that the Bard Monopty biopsy device in association with ultrasonography provides for a safe and reliable technique to perform percutaneous renal biopsy in children.
