Which fascia separates the prostate and rectum and is an important landmark for radical prostatectomy?

• A. Denonvilliers fascia
• B. Buck's fascia
• C. Pelvic fascia
• D. Cremasteric fascia

Answer: (A)

Denonvilliers fascia, also called the rectoprostatic fascia, sits between the posterior surface of the prostate and the anterior wall of the rectum. This separation is what makes it a crucial landmark during radical prostatectomy: identifying this fascia helps the surgeon stay in the correct posterior dissection plane, allowing removal of the prostate while preserving surrounding structures and minimizing the risk of rectal injury. Buck's fascia encases the penis, cremasteric fascia surrounds the spermatic cord, and pelvic fascia is a broader pelvic connective tissue layer, none of which specifically separate the prostate from the rectum.
