The basis of the perineal prostatectomy is an exact knowledge of the anatomical structures of the perineum.
In the literature, however, the description of the anatomical structures of the perineum, particularly of the rectourethral muscle and Denonvilliers' fascia, is very vague and indefinite.
The writer, therefore, taking adult bodies and fetuses, examined in detail the subcutaneous tissue, muscles, fasciae and ligaments, comparing them with those recorded in the past, and is here going to give his conclusion by mentioning what are different from those mentioned in the past documents.
