[Transrectal prostatic sonography. Evaluation of a pilot study].

The method of transrectal prostatic sonography is described. Evaluation of over 2700 examinations indicates a sensitivity and specificity for prostatic carcinomas of 88.7% and 97.3% respectively. The value of this new imaging method for the early recognition of an early carcinoma, for its staging and for controlling treatment has been investigated. Sonographic determination of the size of the prostate and a comparison of the transrectal and suprapubic approach are discussed.
