THE INCREASING use of percutaneous aspiration techniques has led to a variety of alternatives to surgical procedures for patients with diagnostic problems relating to the kidney and perirenal areas. The accessibility of the genitourinary tract to ultrasound and the absence of radiation afforded by its use make ultrasound a desirable modality for a number of interventional procedures. Table 1 lists the spectrum of diagnostic and therapeutic interventional procedures performed under sonographic guidance at the Montefiore Medical Center from 1975 to May 1983.

Renal Biopsy  The kidney was one of the first organs to be selected for percutaneous biopsy. In the past 30 years, the superiority of percutaneous biopsy over open biopsy has been well established for its high yield and low morbidity.1 Both ultrasonic and fluoroscopic localization techniques are considered equal in accuracy. Ultrasound is advantageous because it is a gross anatomic examination and does not depend on renal
