Selective renal biopsy under ultrasonic real-time guidance

Abstract

A new technique for performing renal biopsy using ultrasonic real-time guidance was developed at our clinic in 1978. The puncture procedure is monitored in 2-dimensional real-time images by a mechanical sector scanner equipped with an attachment for needle guidance. The technique is called “selective renal biopsy” because tissue can be obtained selectively from any portion of the kidney. During the last 4 years, 150 such procedures have been performed on 148 patients. The success rate has been 96%. No serious complications occurred.
