[Experience with transrectal ultrasonic studies in patients with prostatic tumors]

The authors present the most typical forms of the prostatic cancer imaged by transrectal ultrasound. They compared the results of investigations of two tumor markers [prostatic specific antigen (PSA), prostatic acid phosphatase (PAP),] the transrectal ultrasound and the rectal palpation. The sensibility of PSA, the ultrasound and the digital investigation were almost the same. The valuability of the transrectal ultrasound investigation in the early diagnosis is limited, but important to determine the stage of the disease, monitoring the process, control of the proper treatment, and in some differential diagnostical problems of the prostate.
