title: [Prostate cancer and transrectal ultrasound].
abstract: We describe the ultrasonographic changes prostate cancer can produce, and analyze the usefulness of ultrasonography in the study of this disease. Transrectal ultrasound does not have enough sensitivity and specificity for the diagnosis, metastasic study, and diagnosis of recurrences after radical prostatectomy. Nevertheless the ultrasound study of the morphology of the prostatic apex may be useful for the planning and performance of the apex dissection during radical prostatectomy.
