[Suprapubic prostatic sonography in the diagnosis of carcinomas and adenomas of the prostate (author's transl)].

Prostatic adenomas and carcinomas were examined by suprapubic transvesical prostatic sonography. The value of the method is comparable with transrectal prostatic sonography. Adenomas and carcinomas can be differentiated on the basis of their echo patterns and marginal contours. In the presence of carcinomas, sonography is a valuable addition to clinical staging and staging by CT. Compared with CT, the ability to perform longitudinal sections permits good evaluation of the bladder base. Sonography is also valuable for serial observations after treatment and for diagnosing recurrences.
