Transurethral ultrasonotomography of the prostate.
Newly developed transurethral ultrasonic scanners were used to study 20 patients with histologically proven prostatic cancer. Fifty-two patients with or without other prostatic disease were also evaluated. The characteristic findings of prostatic cancer were asymmetry of the shape (85%), ill-defined contour (75%), protruded areas from the boundary (70%), elongation of anteroposterior diameter (65%), and enlargement of the prostate (65%). In addition, transurethral ultrasonography delineated a clearer contour of the prostate compared with the transrectal procedure.
