[Use of transrectal ultrasonography in prostate pathology: determination and clinical usefulness of the prostate transition zone].
The prostate gland comprises a central or transition zone which is the object of an important hypertrophy in case of benign prostatic hypertrophy and a peripheral zone where the vast majority of cancers occurs. The ultrasonographic measurement of the prostate transition zone volume has become a very important parameter to consider in the assessment of the severity of symptoms or the therapeutic options in case of benign prostatic hyperplasia. When a prostate cancer is suspected, a new concept, the prostate specific antigen density related to the transition zone volume, has been demonstrated as a very effective mean for prostate cancer early detection in men with PSA levels below 10 ng/ml.
