Endoscopic ultrasonic evaluation of the prostate using a transrectal probe: prospective evaluation and acoustic characterization.

abstract：:Previous reports of angiomyolipoma have emphasized the ultrasonic finding of a very echogenic intrarenal mass. Ten cases of angiomyolipoma for which ultrasound examinations were available were retrospectively reviewed and correlated with their pathologic findings, and, when available, with computed tomographic finding...
