IMAGE-DIRECTED AND COLOR DOPPLER ULTRASONOGRAPHY IN THE DIAGNOSIS OF POSTBIOPSY ARTERIOVENOUS-FISTULAS OF NATIVE KIDNEYS

Using image-directed and color Doppler ultrasonography (ICDUS), we exa mined 65 patients with single kidney biopsy and diagnosed one arteriov enous fistula (AVF) in each of 8 kidneys. Three of them were associate d with pseudoaneurysms. Three of the patients with AVF who presented w ith macrohematuria underwent angiography. Therapeutic percutaneous emb olization was performed in 2 of them. The remaining 6 patients were fo llowed up with ICDUS. All the lesions had disappeared at the end of a 6-month period. We conclude that ICDUS is an easy and noninvasive imag ing technique in the diagnosis of postbiopsy native renal AVFs. (C) 19 95 John Wiley & Sons, Inc.
