Editing Prostate (section)

=== Venous Drainage ===

* The veins of the prostate drain into the Santorini/periprostatic plexus
* '''The periprostatic plexus anastomoses with the deep dorsal vein of the penis and the internal iliac (hypogastric) veins'''
* '''The deep dorsal vein leaves the penis under the Buck fascia between the corpora cavernosa and penetrates the urogenital diaphragm, with the common trunk dividing into 3 major branches:'''
*# '''Superficial branch'''
*# '''Right lateral venous plexuses'''
*# '''Left lateral venous plexuses'''
** '''Superficial branch'''
*** '''The centrally located vein overlying the bladder neck and prostate'''
*** '''Lies in the retropubic fat outside the anterior prostatic fascia'''.
*** '''Travels between the puboprostatic ligaments'''
*** Easily visualized early in retropubic operations and has communicating branches over the bladder itself and into the endopelvic fascia.
** '''Right and left lateral venous plexuses'''
*** Traverse posterolaterally
*** Communicate freely with the pudendal, obturator, and vesical plexuses, which form the inferior vesical vein, which empties into the internal iliac vein.
** '''The common trunk (including deep dorsal vein complex) and lateral venous plexuses are covered by the prostatic and endopelvic/levator fascia.'''
