[A comparative evaluation between transrectal echography, venous urography, computerized axial tomography and morphology in patients with prostatic carcinoma].

Prostate cancer is a rather common and severe disease in man. It affects the age beyond 50, a tendency being recently observed towards affecting subjects of younger age. In the early stage the symptoms are scarce and vague. The diagnostic possibilities of ultrasound examination, intravenous urography, computer axial tomography and biopsy specimen examination were compared in patients with prostate cancer. The authors consider the possibilities of transabdominal and transrectal echography for diagnosis of prostate cancer to be superior to those of intravenous urography. H. Watanabe even recommends and uses transrectal echography as screening method. The possibilities and results of transrectal echography and computer axial tomography for evaluating tumor growth and infiltration outside the prostate capsule are compared. Ultrasound examination is recommended as a more exact method, with a view to radical prostatectomy. The good correlation of the echographic patterns with tumor development are also recorded.
