title: Sonourethrography: technique for evaluation of prostatic urethra.
abstract: Sonoendoscopy of the prostate was extended to include the prostatic urethra, using the transrectal approach so as to show the urethra during voiding. In addition to the normal urethra, nodules impinging upon and displacing the prostatic urethra were clearly demonstrated, as well as clinically unsuspected carcinomas and other abnormalities.
