[Retropubic radical prostatectomy. I. Denonvilliers' aponeurosis, prostatic "pseudocapsule" and the external striated urethral sphincter].

: The present paper reviews the histological characteristics of the prostatic "pseudocapsule", Denonvilliers' aponeurosis and the external striated urethral sphincter. This morphological study has been conducted on pieces of prostate obtained through necropsies. We believe that the knowledge of the morphological characteristics of these structures as well as their relationships is necessary in order to perform the technique of radical retropubic prostatectomy.
