Prostate Anatomy

 Fig. 1 Axial section of prostate and periprostatic fascias at midprostate: (a) anatomic (reproduced with permission from the Mayo Clinic); (b) schematic.
AFS = anterior fibromuscular stroma; C = capsule of prostate; DA = detrusor apron; DVC = dorsal vascular complex; ED = ejaculatory ducts; FTAP = fascial tendinous arch of pelvis; LA = levator ani muscle; LAF = levator ani fascia; NVB = neurovascular bundle; PB = pubic bone; PEF = parietal endopelvic fascia; PF = prostatic fascia; pPF/SVF = posterior prostatic fascia/seminal vesicles fascia (Denonvilliers’ fascia); PZ = peripheral zone; R = rectum; TZ = transition zone; U = urethra; VEF = visceral endopelvic fascia.

 Fig. 2 Midline sagittal section of prostate, bladder, urethra, and striated sphincter: (a) anatomic (reproduced with permission from the Mayo Clinic); (b) schematic.
B = bladder; C = capsule of prostate; CS = colliculus seminalis (verumontanum); DA = detrusor apron; DVC = dorsal vascular complex; MDR = medial dorsal raphe; PS = pubic symphysis; pPF/SVF = posterior prostatic fascia/seminal vesicle fascia (Denonvilliers’ fascia); R = rectum; RU = rectourethralis muscle; SMS = smooth muscle sphincter (lissosphincter); SS = striated sphincter (rhabdosphincter); U = urethra; VEF = visceral endopelvic fascia; VPM = vesicoprostatic muscle.

 Fig. 3 Axial section of sphincteric urethra: (a) anatomic (reproduced with permission from the Mayo Clinic); (b) schematic.
DVC = dorsal vascular complex; LAF = levator ani fascia; MDR = median dorsal raphe; NVB = neurovascular bundle; PB = pubic bone; PV/PPL = pubovesical/puboprostatic ligament; pp = puboperinealis muscle; PR = puborectalis muscle; R = rectum; RU = rectourethralis muscle; SS = striated sphincter (rhabdosphincter); C SMS = circular smooth muscle sphincter (lissosphincter); L SMS = longitudinal smooth muscle sphincter (lissosphincter); U = urethra; VEF = visceral endopelvic fascia.

B = bladder; C = capsule of prostate; CS = colliculus seminalis (verumontanum); CZ = central zone; ED = ejaculatory duct; LA = levator ani muscle; LAF = levator ani fascia; NVB = neurovascular bundle; OI = obturator internus muscle; PEF = parietal endopelvic fascia; PF = prostatic fascia; PZ = peripheral zone; SMS = smooth muscle sphincter (lissosphincter); SS = striated sphincter (rhabdosphincter); SV = seminal vesicle; U = urethra; VD = vas deferens; VP = vascular pedicle to prostate.
