[Ultrasonically guided puncture of the prostate and seminal vesicles].

Ultrasonically guided puncture of the prostate was carried out in 10 patients with prostatic disease. Biopsy of the aiming portion of the prostate was performed with more certainty and safety by this method than the conventional blind procedure. In the 15 cases having the suspicion of seminal vesicle disorder, the seminal vesicle was punctured under ultrasound control. By this procedure, the seminal vesicle fluid was safely and accurately obtained.
