Anatomical basis of total prostatocystectomy in man

In the first part of this paper special emphasis is given to the anatomy of Denonvillier 's fascia which is derived from the prostatic capsule and covers the seminal vesicles, and to the preprostatic veins. In the second part devoted to the surgical technique of total prostatocystectomy the authors propose that the vesicoprostatic unit be freed by dissecting posterior to Denonvillier 's fascia. It is also proposed that the membranous urethra be sectioned prior to performing hemostasis of the preprostatic veins.
