    Area of Science:

    • Anatomy
    • Surgical Anatomy
    • Urology

    Background:

    • Understanding the precise anatomical structures involved in total cystoprostatectomy is crucial for surgical success.
    • Denonvilliers' fascia and associated vascular structures require detailed description for safe dissection.

    Purpose of the Study:

    • To anatomically delineate the layers of Denonvilliers' fascia during total cystoprostatectomy.
    • To clarify the attachments and anatomical course of preprostatic veins.
    • To define critical dissection planes for total cystoprostatectomy.

    Main Methods:

    • Anatomical dissection study focusing on the pelvic region relevant to cystoprostatectomy.
    • Detailed examination of Denonvilliers' fascia and surrounding vascular network.

    Main Results:

    • Denonvilliers' fascia is characterized by multiple membranous layers originating from the bladder.
    • Preprostatic veins connect to the venae dorsales penis and venae pudendae internae.
    • These veins are embedded within a muscular and collagenous tissue layer anterior to the bladder.

    Conclusions:

    • The interprostaticorectal dissection plane lies posterior to Denonvilliers' fascia.
    • The preprostatic vein dissection plane is situated anterior to the membranous urethra.
    • This anatomical understanding aids in optimizing surgical technique for total cystoprostatectomy.
