title: Anatomical study of total cystoprostatectomy.
abstract: The authors describe an anatomical study of total cystoprostatectomy. They show that Denonvilliers' fascia is made up of many membranous layers starting at the bladder. They recall the fact that the preprostatic veins are attached at the bottom, not only to the venae dorsales penis, but also to the venae pudendae internae which runs under the levator ani muscle. These preprostatic veins lie inside a vessel-bearing blade of tissue made of muscular and collagenous tissue derived from the anterior vesical wall. This anatomical study recalls the fact that the interprostatorectal dissection line is behind Denonvilliers' fascia and that the preprostatic vein dissection line is on the anterior aspect of the membranous urethra.
