title: [Reliability of endorectal echography of the prostate in the screening and staging of prostatic cancer].
abstract: 1433 transrectal ultrasonographies were performed for prostatic disease. In 453 cases, histopathologic correlation was obtained and compared to digital rectal examination and transrectal ultrasonography done after the clinical examination. The sensitivity of digital rectal examination was 91% and the specificity was 85%. The sensitivity and the specificity of ultrasonography were respectively 95 and 81%. 4 prostatic cancers, not suspected by digital rectal examination, were diagnosed by ultrasound (0,9%). The total number of subclinical cancer was 9 (2%). Interest of ultrasound compared to digital rectal examination concerns less than 1% of the total number of controlled patients. The staging of local extension of prostatic cancer is better by ultrasound than by the digital rectal examination. On 9 cases of clinical unsuspected extracapsular invasion, 6 were diagnosed by ultrasound.
